We believe that the most powerful and differentiated applications will not only call out to a language model via an API, but will also:\nBe data-aware: connect a language model to other sources of data\nBe agentic: allow a language model to interact with its environment\nThe LangChain framework is designed with the above principles in mind.\nThis is the Python specific portion of the documentation. For a purely conceptual guide to LangChain, see here. For the JavaScript documentation, see here.\nGetting Started#\nCheckout the below guide for a walkthrough of how to get started using LangChain to create an Language Model application.\nGetting Started Documentation\nModules#\nThere are several main modules that LangChain provides support for.\nFor each module we provide some examples to get started, how-to guides, reference docs, and conceptual guides.\nThese modules are, in increasing order of complexity:\nModels: The various model types and model integrations LangChain supports.\nPrompts: This includes prompt management, prompt optimization, and prompt serialization.\nMemory: Memory is the concept of persisting state between calls of a chain/agent. LangChain provides a standard interface for memory, a collection of memory implementations, and examples of chains/agents that use memory.\nIndexes: Language models are often more powerful when combined with your own text data - this module covers best practices for doing exactly that.", "source": "/content/https://python.langchain.com/en/latest/index.html"}
+{"id": "da02d52f8f8f-1", "text": "Chains: Chains go beyond just a single LLM call, and are sequences of calls (whether to an LLM or a different utility). LangChain provides a standard interface for chains, lots of integrations with other tools, and end-to-end chains for common applications.\nAgents: Agents involve an LLM making decisions about which Actions to take, taking that Action, seeing an Observation, and repeating that until done. LangChain provides a standard interface for agents, a selection of agents to choose from, and examples of end to end agents.\nUse Cases#\nThe above modules can be used in a variety of ways. LangChain also provides guidance and assistance in this. Below are some of the common use cases LangChain supports.\nAutonomous Agents: Autonomous agents are long running agents that take many steps in an attempt to accomplish an objective. Examples include AutoGPT and BabyAGI.\nAgent Simulations: Putting agents in a sandbox and observing how they interact with each other or to events can be an interesting way to observe their long-term memory abilities.\nPersonal Assistants: The main LangChain use case. Personal assistants need to take actions, remember interactions, and have knowledge about your data.\nQuestion Answering: The second big LangChain use case. Answering questions over specific documents, only utilizing the information in those documents to construct an answer.\nChatbots: Since language models are good at producing text, that makes them ideal for creating chatbots.\nQuerying Tabular Data: If you want to understand how to use LLMs to query data that is stored in a tabular format (csvs, SQL, dataframes, etc) you should read this page.", "source": "/content/https://python.langchain.com/en/latest/index.html"}

A type of Data Augmented Generation.\nEvaluation: Generative models are notoriously hard to evaluate with traditional metrics. One new way of evaluating them is using language models themselves to do the evaluation. LangChain provides some prompts/chains for assisting in this.\nReference Docs#\nAll of LangChain\u2019s reference documentation, in one place.

By leveraging VectorStores, Conversational RetrieverChain, and GPT-4, it can answer questions in the context of an entire GitHub repository or generate new code. This documentation page outlines the essential components of the system and guides using LangChain for better code comprehension, contextual question answering, and code generation in GitHub repositories.\nConversational Retriever Chain#\nConversational RetrieverChain is a retrieval-focused system that interacts with the data stored in a VectorStore. Utilizing advanced techniques, like context-aware filtering and ranking, it retrieves the most relevant code snippets and information for a given user query. Conversational RetrieverChain is engineered to deliver high-quality, pertinent results while considering conversation history and context.\nLangChain Workflow for Code Understanding and Generation\nIndex the code base: Clone the target repository, load all files within, chunk the files, and execute the indexing process. Optionally, you can skip this step and use an already indexed dataset.\nEmbedding and Code Store: Code snippets are embedded using a code-aware embedding model and stored in a VectorStore.\nQuery Understanding: GPT-4 processes user queries, grasping the context and extracting relevant details.\nConstruct the Retriever: Conversational RetrieverChain searches the VectorStore to identify the most relevant code snippets for a given query.", "source": "/content/https://python.langchain.com/en/latest/use_cases/code.html"}

+{"id": "f3aaf80350d4-1", "text": "Overview:\nThe rapid advancement of conversational and chat-based language models has led to remarkable progress in complex task-solving. However, their success heavily relies on human input to guide the conversation, which can be challenging and time-consuming. This paper explores the potential of building scalable techniques to facilitate autonomous cooperation among communicative agents and provide insight into their \u201ccognitive\u201d processes. To address the challenges of achieving autonomous cooperation, we propose a novel communicative agent framework named role-playing. Our approach involves using inception prompting to guide chat agents toward task completion while maintaining consistency with human intentions. We showcase how role-playing can be used to generate conversational data for studying the behaviors and capabilities of chat agents, providing a valuable resource for investigating conversational language models. Our contributions include introducing a novel communicative agent framework, offering a scalable approach for studying the cooperative behaviors and capabilities of multi-agent systems, and open-sourcing our library to support research on communicative agents and beyond.\nThe original implementation: https://github.com/lightaime/camel\nProject website: https://www.camel-ai.org/\nArxiv paper: https://arxiv.org/abs/2303.17760\nImport LangChain related modules#\nfrom typing import List\nfrom langchain.chat_models import ChatOpenAI\nfrom langchain.prompts.chat import (\n    SystemMessagePromptTemplate,\n    HumanMessagePromptTemplate,\n)\nfrom langchain.schema import (\n    AIMessage,\n    HumanMessage,\n    SystemMessage,\n    BaseMessage,\n)\nDefine a CAMEL agent helper class#\nclass CAMELAgent:", "source": "/content/https://python.langchain.com/en/latest/use_cases/agent_simulations/camel_role_playing.html"}

+{"id": "083c8c486787-4", "text": "-> Question: What does favCountParams do?\nAnswer: favCountParams is an optional ThriftLinearFeatureRankingParams instance that represents the parameters related to the \u201cfavorite count\u201d feature in the ranking process. It is used to control the weight of the favorite count feature while ranking tweets. The favorite count is the number of times a tweet has been marked as a favorite by users, and it is considered an important signal in the ranking of tweets. By using favCountParams, the system can adjust the importance of the favorite count while calculating the final ranking score of a tweet.\n-> Question: is it Likes + Bookmarks, or not clear from the code?\nAnswer: From the provided code, it is not clear if the favorite count metric is determined by the sum of likes and bookmarks. The favorite count is mentioned in the code, but there is no explicit reference to how it is calculated in terms of likes and bookmarks.\n-> Question: What are the major negative modifiers that lower your linear ranking parameters?\nAnswer: In the given code, major negative modifiers that lower the linear ranking parameters are:\nscoringData.querySpecificScore: This score adjustment is based on the query-specific information.

If its value is negative, it will also lower the linear ranking parameters.\nPlease note that I cannot provide more information on the exact calculations of these negative modifiers, as the code for their determination is not provided.\n-> Question: How do you get assigned to SimClusters?", "source": "/content/https://python.langchain.com/en/latest/use_cases/code/twitter-the-algorithm-analysis-deeplake.html"}
+{"id": "083c8c486787-5", "text": "-> Question: How do you get assigned to SimClusters?\nAnswer: The assignment to SimClusters occurs through a Metropolis-Hastings sampling-based community detection algorithm that is run on the Producer-Producer similarity graph. This graph is created by computing the cosine similarity scores between the users who follow each producer. The algorithm identifies communities or clusters of Producers with similar followers, and takes a parameter k for specifying the number of communities to be detected.\nAfter the community detection, different users and content are represented as sparse, interpretable vectors within these identified communities (SimClusters). The resulting SimClusters embeddings can be used for various recommendation tasks.\n-> Question: What is needed to migrate from one SimClusters to another SimClusters?\nAnswer: To migrate from one SimClusters representation to another, you can follow these general steps:\nPrepare the new representation: Create the new SimClusters representation using any necessary updates or changes in the clustering algorithm, similarity measures, or other model parameters. Ensure that this new representation is properly stored and indexed as needed.\nUpdate the relevant code and configurations: Modify the relevant code and configuration files to reference the new SimClusters representation. This may involve updating paths or dataset names to point to the new representation, as well as changing code to use the new clustering method or similarity functions if applicable.", "source": "/content/https://python.langchain.com/en/latest/use_cases/code/twitter-the-algorithm-analysis-deeplake.html"}
+{"id": "083c8c486787-6", "text": "Test the new representation: Before deploying the changes to production, thoroughly test the new SimClusters representation to ensure its effectiveness and stability. This may involve running offline jobs like candidate generation and label candidates, validating the output, as well as testing the new representation in the evaluation environment using evaluation tools like TweetSimilarityEvaluationAdhocApp.\nDeploy the changes: Once the new representation has been tested and validated, deploy the changes to production. This may involve creating a zip file, uploading it to the packer, and then scheduling it with Aurora. Be sure to monitor the system to ensure a smooth transition between representations and verify that the new representation is being used in recommendations as expected.\nMonitor and assess the new representation: After the new representation has been deployed, continue to monitor its performance and impact on recommendations. Take note of any improvements or issues that arise and be prepared to iterate on the new representation if needed. Always ensure that the results and performance metrics align with the system\u2019s goals and objectives.\n-> Question: How much do I get boosted within my cluster?\nAnswer: It\u2019s not possible to determine the exact amount your content is boosted within your cluster in the SimClusters representation without specific data about your content and its engagement metrics. However, a combination of factors, such as the favorite score and follow score, alongside other engagement signals and SimCluster calculations, influence the boosting of content.\n-> Question: How does Heavy ranker work. what are it\u2019s main inputs?", "source": "/content/https://python.langchain.com/en/latest/use_cases/code/twitter-the-algorithm-analysis-deeplake.html"}
+{"id": "083c8c486787-7", "text": "-> Question: How does Heavy ranker work. what are it\u2019s main inputs?\nAnswer: The Heavy Ranker is a machine learning model that plays a crucial role in ranking and scoring candidates within the recommendation algorithm. Its primary purpose is to predict the likelihood of a user engaging with a tweet or connecting with another user on the platform.\nMain inputs to the Heavy Ranker consist of:\nStatic Features: These are features that can be computed directly from a tweet at the time it\u2019s created, such as whether it has a URL, has cards, has quotes, etc. These features are produced by the Index Ingester as the tweets are generated and stored in the index.\nReal-time Features: These per-tweet features can change after the tweet has been indexed. They mostly consist of social engagements like retweet count, favorite count, reply count, and some spam signals that are computed with later activities. The Signal Ingester, which is part of a Heron topology, processes multiple event streams to collect and compute these real-time features.\nUser Table Features: These per-user features are obtained from the User Table Updater that processes a stream written by the user service. This input is used to store sparse real-time user information, which is later propagated to the tweet being scored by looking up the author of the tweet.\nSearch Context Features: These features represent the context of the current searcher, like their UI language, their content consumption, and the current time (implied). They are combined with Tweet Data to compute some of the features used in scoring.\nThese inputs are then processed by the Heavy Ranker to score and rank candidates based on their relevance and likelihood of engagement by the user.", "source": "/content/https://python.langchain.com/en/latest/use_cases/code/twitter-the-algorithm-analysis-deeplake.html"}
+{"id": "083c8c486787-8", "text": "-> Question: How can one influence Heavy ranker?\nAnswer: To influence the Heavy Ranker\u2019s output or ranking of content, consider the following actions:\nImprove content quality: Create high-quality and engaging content that is relevant, informative, and valuable to users. High-quality content is more likely to receive positive user engagement, which the Heavy Ranker considers when ranking content.\nIncrease user engagement: Encourage users to interact with content through likes, retweets, replies, and comments. Higher engagement levels can lead to better ranking in the Heavy Ranker\u2019s output.\nOptimize your user profile: A user\u2019s reputation, based on factors such as their follower count and follower-to-following ratio, may impact the ranking of their content. Maintain a good reputation by following relevant users, keeping a reasonable follower-to-following ratio and engaging with your followers.\nEnhance content discoverability: Use relevant keywords, hashtags, and mentions in your tweets, making it easier for users to find and engage with your content. This increased discoverability may help improve the ranking of your content by the Heavy Ranker.\nLeverage multimedia content: Experiment with different content formats, such as videos, images, and GIFs, which may capture users\u2019 attention and increase engagement, resulting in better ranking by the Heavy Ranker.\nUser feedback: Monitor and respond to feedback for your content. Positive feedback may improve your ranking, while negative feedback provides an opportunity to learn and improve.\nNote that the Heavy Ranker uses a combination of machine learning models and various features to rank the content. While the above actions may help influence the ranking, there are no guarantees as the ranking process is determined by a complex algorithm, which evolves over time.\n-> Question: why threads and long tweets do so well on the platform?", "source": "/content/https://python.langchain.com/en/latest/use_cases/code/twitter-the-algorithm-analysis-deeplake.html"}
+{"id": "083c8c486787-9", "text": "-> Question: why threads and long tweets do so well on the platform?\nAnswer: Threads and long tweets perform well on the platform for several reasons:\nMore content and context: Threads and long tweets provide more information and context about a topic, which can make the content more engaging and informative for users. People tend to appreciate a well-structured and detailed explanation of a subject or a story, and threads and long tweets can do that effectively.\nIncreased user engagement: As threads and long tweets provide more content, they also encourage users to engage with the tweets through replies, retweets, and likes. This increased engagement can lead to better visibility of the content, as the Twitter algorithm considers user engagement when ranking and surfacing tweets.\nNarrative structure: Threads enable users to tell stories or present arguments in a step-by-step manner, making the information more accessible and easier to follow. This narrative structure can capture users\u2019 attention and encourage them to read through the entire thread and interact with the content.\nExpanded reach: When users engage with a thread, their interactions can bring the content to the attention of their followers, helping to expand the reach of the thread. This increased visibility can lead to more interactions and higher performance for the threaded tweets.\nHigher content quality: Generally, threads and long tweets require more thought and effort to create, which may lead to higher quality content. Users are more likely to appreciate and interact with high-quality, well-reasoned content, further improving the performance of these tweets within the platform.\nOverall, threads and long tweets perform well on Twitter because they encourage user engagement and provide a richer, more informative experience that users find valuable.\n-> Question: Are thread and long tweet creators building a following that reacts to only threads?", "source": "/content/https://python.langchain.com/en/latest/use_cases/code/twitter-the-algorithm-analysis-deeplake.html"}
+{"id": "083c8c486787-10", "text": "Answer: Based on the provided code and context, there isn\u2019t enough information to conclude if the creators of threads and long tweets primarily build a following that engages with only thread-based content. The code provided is focused on Twitter\u2019s recommendation and ranking algorithms, as well as infrastructure components like Kafka, partitions, and the Follow Recommendations Service (FRS). To answer your question, data analysis of user engagement and results of specific edge cases would be required.\n-> Question: Do you need to follow different strategies to get most followers vs to get most likes and bookmarks per tweet?\nAnswer: Yes, different strategies need to be followed to maximize the number of followers compared to maximizing likes and bookmarks per tweet. While there may be some overlap in the approaches, they target different aspects of user engagement.\nMaximizing followers: The primary focus is on growing your audience on the platform. Strategies include:\nConsistently sharing high-quality content related to your niche or industry.\nEngaging with others on the platform by replying, retweeting, and mentioning other users.\nUsing relevant hashtags and participating in trending conversations.\nCollaborating with influencers and other users with a large following.\nPosting at optimal times when your target audience is most active.\nOptimizing your profile by using a clear profile picture, catchy bio, and relevant links.\nMaximizing likes and bookmarks per tweet: The focus is on creating content that resonates with your existing audience and encourages engagement. Strategies include:\nCrafting engaging and well-written tweets that encourage users to like or save them.\nIncorporating visually appealing elements, such as images, GIFs, or videos, that capture attention.\nAsking questions, sharing opinions, or sparking conversations that encourage users to engage with your tweets.", "source": "/content/https://python.langchain.com/en/latest/use_cases/code/twitter-the-algorithm-analysis-deeplake.html"}

However, it\u2019s essential to recognize that maximizing followers and maximizing likes and bookmarks per tweet have different focuses and require specific strategies.\n-> Question: Content meta data and how it impacts virality (e.g. ALT in images).\nAnswer: There is no direct information in the provided context about how content metadata, such as ALT text in images, impacts the virality of a tweet or post. However, it\u2019s worth noting that including ALT text can improve the accessibility of your content for users who rely on screen readers, which may lead to increased engagement for a broader audience. Additionally, metadata can be used in search engine optimization, which might improve the visibility of the content, but the context provided does not mention any specific correlation with virality.\n-> Question: What are some unexpected fingerprints for spam factors?\nAnswer: In the provided context, an unusual indicator of spam factors is when a tweet contains a non-media, non-news link. If the tweet has a link but does not have an image URL, video URL, or news URL, it is considered a potential spam vector, and a threshold for user reputation (tweepCredThreshold) is set to MIN_TWEEPCRED_WITH_LINK.", "source": "/content/https://python.langchain.com/en/latest/use_cases/code/twitter-the-algorithm-analysis-deeplake.html"}

The code snippet provided mentions \u201cBlue-verified account boost\u201d which indicates that there is a separate category for blue verified accounts. Typically, blue verified checkmarks are used to indicate notable individuals, while verified checkmarks are for companies or organizations.\n Contents\n  \n1. Index the code base (optional)\n2.

This is useful because (1) plugins use OpenAPI endpoints under the hood, (2) wrapping them in an NLAChain allows the router agent to call it more easily.\nThe novel idea introduced in this notebook is the idea of using retrieval to select not the tools explicitly, but the set of OpenAPI specs to use. We can then generate tools from those OpenAPI specs. The use case for this is when trying to get agents to use plugins. It may be more efficient to choose plugins first, then the endpoints, rather than the endpoints directly. This is because the plugins may contain more useful information for selection.\nSet up environment#\nDo necessary imports, etc.\nfrom langchain.agents import Tool, AgentExecutor, LLMSingleActionAgent, AgentOutputParser\nfrom langchain.prompts import StringPromptTemplate\nfrom langchain import OpenAI, SerpAPIWrapper, LLMChain\nfrom typing import List, Union\nfrom langchain.schema import AgentAction, AgentFinish\nfrom langchain.agents.agent_toolkits import NLAToolkit", "source": "/content/https://python.langchain.com/en/latest/use_cases/agents/custom_agent_with_plugin_retrieval.html"}

This is a situation where you have an example containing a question and its corresponding ground truth answer, and you want to measure how well the language model does at answering those questions.\nSetup#\nFor demonstration purposes, we will just evaluate a simple question answering system that only evaluates the model\u2019s internal knowledge. Please see other notebooks for examples where it evaluates how the model does at question answering over data not present in what the model was trained on.\nfrom langchain.prompts import PromptTemplate\nfrom langchain.chains import LLMChain\nfrom langchain.llms import OpenAI\nprompt = PromptTemplate(template=\"Question: {question}\\nAnswer:\", input_variables=[\"question\"])\nllm = OpenAI(model_name=\"text-davinci-003\", temperature=0)\nchain = LLMChain(llm=llm, prompt=prompt)\nExamples#\nFor this purpose, we will just use two simple hardcoded examples, but see other notebooks for tips on how to get and/or generate these examples.\nexamples = [\n    {\n        \"question\": \"Roger has 5 tennis balls. He buys 2 more cans of tennis balls. Each can has 3 tennis balls.

Joao Moutinho is a professional soccer player, not an American football player, so it is not likely that he would be catching a screen pass in the NFC championship.'}]\nEvaluation#\nWe can see that if we tried to just do exact match on the answer answers (11 and No) they would not match what the language model answered. However, semantically the language model is correct in both cases. In order to account for this, we can use a language model itself to evaluate the answers.\nfrom langchain.evaluation.qa import QAEvalChain\nllm = OpenAI(temperature=0)\neval_chain = QAEvalChain.from_llm(llm)\ngraded_outputs = eval_chain.evaluate(examples, predictions, question_key=\"question\", prediction_key=\"text\")\nfor i, eg in enumerate(examples):\n    print(f\"Example {i}:\")\n    print(\"Question: \" + eg['question'])\n    print(\"Real Answer: \" + eg['answer'])\n    print(\"Predicted Answer: \" + predictions[i]['text'])\n    print(\"Predicted Grade: \" + graded_outputs[i]['text'])\n    print()\nExample 0:", "source": "/content/https://python.langchain.com/en/latest/use_cases/evaluation/question_answering.html"}

Here is an example prompting it using a score from 0 to 10.\nThe custom prompt requires 3 input variables: \u201cquery\u201d, \u201canswer\u201d and \u201cresult\u201d.

You would need a \"context\" input that reflects what the information the LLM uses to answer the question. This context can be obtained by any retreival system.

Modules can be combined to create more complex applications, or be used individually for simple applications.\nLLMs: Get predictions from a language model#\nThe most basic building block of LangChain is calling an LLM on some input.\nLet\u2019s walk through a simple example of how to do this.\nFor this purpose, let\u2019s pretend we are building a service that generates a company name based on what the company makes.\nIn order to do this, we first need to import the LLM wrapper.\nfrom langchain.llms import OpenAI\nWe can then initialize the wrapper with any arguments.\nIn this example, we probably want the outputs to be MORE random, so we\u2019ll initialize it with a HIGH temperature.\nllm = OpenAI(temperature=0.9)\nWe can now call it on some input!\ntext = \"What would be a good company name for a company that makes colorful socks?\"\nprint(llm(text))\nFeetful of Fun\nFor more details on how to use LLMs within LangChain, see the LLM getting started guide.\nPrompt Templates: Manage prompts for LLMs#\nCalling an LLM is a great first step, but it\u2019s just the beginning.\nNormally when you use an LLM in an application, you are not sending user input directly to the LLM.\nInstead, you are probably taking user input and constructing a prompt, and then sending that to the LLM.\nFor example, in the previous example, the text we passed in was hardcoded to ask for a name for a company that made colorful socks.\nIn this imaginary service, what we would want to do is take only the user input describing what the company does, and then format the prompt with that information.", "source": "/content/https://python.langchain.com/en/latest/getting_started/getting_started.html"}

We can call the .format method to format it.\nprint(prompt.format(product=\"colorful socks\"))\nWhat is a good name for a company that makes colorful socks?\nFor more details, check out the getting started guide for prompts.\nChains: Combine LLMs and prompts in multi-step workflows#\nUp until now, we\u2019ve worked with the PromptTemplate and LLM primitives by themselves. But of course, a real application is not just one primitive, but rather a combination of them.\nA chain in LangChain is made up of links, which can be either primitives like LLMs or other chains.\nThe most core type of chain is an LLMChain, which consists of a PromptTemplate and an LLM.\nExtending the previous example, we can construct an LLMChain which takes user input, formats it with a PromptTemplate, and then passes the formatted response to an LLM.\nfrom langchain.prompts import PromptTemplate\nfrom langchain.llms import OpenAI\nllm = OpenAI(temperature=0.9)\nprompt = PromptTemplate(\n    input_variables=[\"product\"],\n    template=\"What is a good name for a company that makes {product}?\",\n)\nWe can now create a very simple chain that will take user input, format the prompt with it, and then send it to the LLM:", "source": "/content/https://python.langchain.com/en/latest/getting_started/getting_started.html"}

There\u2019s the first chain - an LLM Chain.\nThis is one of the simpler types of chains, but understanding how it works will set you up well for working with more complex chains.\nFor more details, check out the getting started guide for chains.\nAgents: Dynamically Call Chains Based on User Input#\nSo far the chains we\u2019ve looked at run in a predetermined order.\nAgents no longer do: they use an LLM to determine which actions to take and in what order. An action can either be using a tool and observing its output, or returning to the user.\nWhen used correctly agents can be extremely powerful. In this tutorial, we show you how to easily use agents through the simplest, highest level API.\nIn order to load agents, you should understand the following concepts:\nTool: A function that performs a specific duty. This can be things like: Google Search, Database lookup, Python REPL, other chains. The interface for a tool is currently a function that is expected to have a string as an input, with a string as an output.\nLLM: The language model powering the agent.\nAgent: The agent to use. This should be a string that references a support agent class. Because this notebook focuses on the simplest, highest level API, this only covers using the standard supported agents.

But often, you may want a chain or agent to have some concept of \u201cmemory\u201d so that it may remember information about its previous interactions. The clearest and simple example of this is when designing a chatbot - you want it to remember previous messages so it can use context from that to have a better conversation. This would be a type of \u201cshort-term memory\u201d. On the more complex side, you could imagine a chain/agent remembering key pieces of information over time - this would be a form of \u201clong-term memory\u201d. For more concrete ideas on the latter, see this awesome paper.\nLangChain provides several specially created chains just for this purpose. This notebook walks through using one of those chains (the ConversationChain) with two different types of memory.", "source": "/content/https://python.langchain.com/en/latest/getting_started/getting_started.html"}

While chat models use language models under the hood, the interface they expose is a bit different: rather than expose a \u201ctext in, text out\u201d API, they expose an interface where \u201cchat messages\u201d are the inputs and outputs.\nChat model APIs are fairly new, so we are still figuring out the correct abstractions.\nGet Message Completions from a Chat Model#\nYou can get chat completions by passing one or more messages to the chat model. The response will be a message. The types of messages currently supported in LangChain are AIMessage, HumanMessage, SystemMessage, and ChatMessage \u2013 ChatMessage takes in an arbitrary role parameter.

There are lots of Embedding providers (OpenAI, Cohere, Hugging Face, etc) - this class is designed to provide a standard interface for all of them.\nEmbeddings create a vector representation of a piece of text. This is useful because it means we can think about text in the vector space, and do things like semantic search where we look for pieces of text that are most similar in the vector space.\nThe base Embedding class in LangChain exposes two methods: embed_documents and embed_query. The largest difference is that these two methods have different interfaces: one works over multiple documents, while the other works over a single document. Besides this, another reason for having these as two separate methods is that some embedding providers have different embedding methods for documents (to be searched over) vs queries (the search query itself).\nThe following integrations exist for text embeddings.\nAleph Alpha\nAzureOpenAI\nCohere\nFake Embeddings\nHugging Face Hub\nInstructEmbeddings\nJina\nLlama-cpp\nOpenAI\nSageMaker Endpoint Embeddings\nSelf Hosted Embeddings\nSentence Transformers Embeddings\nTensorflowHub\nprevious\nPromptLayer ChatOpenAI\nnext\nAleph Alpha\nBy Harrison Chase\n    \n      \u00a9 Copyright 2023, Harrison Chase.\n      \n  Last updated on Apr 26, 2023.", "source": "/content/https://python.langchain.com/en/latest/modules/models/text_embedding.html"}

A user\u2019s interactions with a language model are captured in the concept of ChatMessages, so this boils down to ingesting, capturing, transforming and extracting knowledge from a sequence of chat messages. There are many different ways to do this, each of which exists as its own memory type.\nIn general, for each type of memory there are two ways to understanding using memory. These are the standalone functions which extract information from a sequence of messages, and then there is the way you can use this type of memory in a chain.\nMemory can return multiple pieces of information (for example, the most recent N messages and a summary of all previous messages). The returned information can either be a string or a list of messages.\nIn this notebook, we will walk through the simplest form of memory: \u201cbuffer\u201d memory, which just involves keeping a buffer of all prior messages. We will show how to use the modular utility functions here, then show how it can be used in a chain (both returning a string as well as a list of messages).\nChatMessageHistory#\nOne of the core utility classes underpinning most (if not all) memory modules is the ChatMessageHistory class. This is a super lightweight wrapper which exposes convienence methods for saving Human messages, AI messages, and then fetching them all.\nYou may want to use this class directly if you are managing memory outside of a chain.", "source": "/content/https://python.langchain.com/en/latest/modules/memory/getting_started.html"}

This can be done easily by first converting the messages to normal python dictionaries, saving those (as json or something) and then loading those. Here is an example of doing that.\nimport json\nfrom langchain.memory import ChatMessageHistory\nfrom langchain.schema import messages_from_dict, messages_to_dict", "source": "/content/https://python.langchain.com/en/latest/modules/memory/getting_started.html"}

This notebook covers how to do that.\nFor this notebook, we will add a custom memory type to ConversationChain. In order to add a custom memory class, we need to import the base memory class and subclass it.\nfrom langchain import OpenAI, ConversationChain\nfrom langchain.schema import BaseMemory\nfrom pydantic import BaseModel\nfrom typing import List, Dict, Any\nIn this example, we will write a custom memory class that uses spacy to extract entities and save information about them in a simple hash table. Then, during the conversation, we will look at the input text, extract any entities, and put any information about them into the context.\nPlease note that this implementation is pretty simple and brittle and probably not useful in a production setting. Its purpose is to showcase that you can add custom memory implementations.\nFor this, we will need spacy.\n# !pip install spacy\n# !python -m spacy download en_core_web_lg\nimport spacy\nnlp = spacy.load('en_core_web_lg')\nclass SpacyEntityMemory(BaseMemory, BaseModel):\n    \"\"\"Memory class for storing information about entities.\"\"\"\n    # Define dictionary to store information about entities.\n    entities: dict = {}\n    # Define key to pass information about entities into prompt.\n    memory_key: str = \"entities\"\n        \n    def clear(self):\n        self.entities = {}\n    @property", "source": "/content/https://python.langchain.com/en/latest/modules/memory/examples/custom_memory.html"}

The purpose of this notebook is to show you how to easily use agents through the simplest, highest level API.\nIn order to load agents, you should understand the following concepts:\nTool: A function that performs a specific duty. This can be things like: Google Search, Database lookup, Python REPL, other chains. The interface for a tool is currently a function that is expected to have a string as an input, with a string as an output.\nLLM: The language model powering the agent.\nAgent: The agent to use. This should be a string that references a support agent class. Because this notebook focuses on the simplest, highest level API, this only covers using the standard supported agents. If you want to implement a custom agent, see the documentation for custom agents (coming soon).\nAgents: For a list of supported agents and their specifications, see here.\nTools: For a list of predefined tools and their specifications, see here.\nfrom langchain.agents import load_tools\nfrom langchain.agents import initialize_agent\nfrom langchain.agents import AgentType\nfrom langchain.llms import OpenAI\nFirst, let\u2019s load the language model we\u2019re going to use to control the agent.\nllm = OpenAI(temperature=0)\nNext, let\u2019s load some tools to use.

Async support for other agent tools are on the roadmap.\nFor Tools that have a coroutine implemented (the two mentioned above), the AgentExecutor will await them directly. Otherwise, the AgentExecutor will call the Tool\u2019s func via asyncio.get_event_loop().run_in_executor to avoid blocking the main runloop.\nYou can use arun to call an AgentExecutor asynchronously.\nSerial vs. Concurrent Execution#\nIn this example, we kick off agents to answer some questions serially vs. concurrently.

The use case for this is that you\u2019ve ingested your data into a vectorstore and want to interact with it in an agentic manner.\nThe recommended method for doing so is to create a RetrievalQA and then use that as a tool in the overall agent. Let\u2019s take a look at doing this below. You can do this with multiple different vectordbs, and use the agent as a way to route between them. There are two different ways of doing this - you can either let the agent use the vectorstores as normal tools, or you can set return_direct=True to really just use the agent as a router.\nCreate the Vectorstore#\nfrom langchain.embeddings.openai import OpenAIEmbeddings\nfrom langchain.vectorstores import Chroma\nfrom langchain.text_splitter import CharacterTextSplitter\nfrom langchain.llms import OpenAI\nfrom langchain.chains import RetrievalQA\nllm = OpenAI(temperature=0)\nfrom pathlib import Path\nrelevant_parts = []\nfor p in Path(\".\").absolute().parts:\n    relevant_parts.append(p)\n    if relevant_parts[-3:] == [\"langchain\", \"docs\", \"modules\"]:\n        break\ndoc_path = str(Path(*relevant_parts) / \"state_of_the_union.txt\")\nfrom langchain.document_loaders import TextLoader\nloader = TextLoader(doc_path)", "source": "/content/https://python.langchain.com/en/latest/modules/agents/agent_executors/examples/agent_vectorstore.html"}

When a user wants information on songs, You want the Agent to use  the custom tool more than the normal Search tool. But the Agent might prioritize a normal Search tool.\nThis can be accomplished by adding a statement such as Use this more than the normal search if the question is about Music, like 'who is the singer of yesterday?' or 'what is the most popular song in 2022?' to the description.\nAn example is below.\n# Import things that are needed generically\nfrom langchain.agents import initialize_agent, Tool\nfrom langchain.agents import AgentType\nfrom langchain.llms import OpenAI\nfrom langchain import LLMMathChain, SerpAPIWrapper", "source": "/content/https://python.langchain.com/en/latest/modules/agents/tools/custom_tools.html"}

So if that step requires multiple inputs, they need to be parsed from that. Therefore, the currently supported way to do this is to write a smaller wrapper function that parses a string into multiple inputs.\nFor a concrete example, let\u2019s work on giving an agent access to a multiplication function, which takes as input two integers. In order to use this, we will tell the agent to generate the \u201cAction Input\u201d as a comma-separated list of length two. We will then write a thin wrapper that takes a string, splits it into two around a comma, and passes both parsed sides as integers to the multiplication function.\nfrom langchain.llms import OpenAI\nfrom langchain.agents import initialize_agent, Tool\nfrom langchain.agents import AgentType\nHere is the multiplication function, as well as a wrapper to parse a string as input.\ndef multiplier(a, b):\n    return a * b\ndef parsing_multiplier(string):\n    a, b = string.split(\",\")\n    return multiplier(int(a), int(b))\nllm = OpenAI(temperature=0)\ntools = [\n    Tool(\n        name = \"Multiplier\",\n        func=parsing_multiplier,", "source": "/content/https://python.langchain.com/en/latest/modules/agents/tools/multi_input_tool.html"}

It has been serialized in Shueisha\\'s sh\u014dnen manga magazine Weekly Sh\u014dnen Jump since March 1998, although the manga has frequently gone on extended hiatuses since 2006. Its chapters have been collected in 37 tank\u014dbon volumes as of November 2022. The story focuses on a young boy named Gon Freecss who discovers that his father, who left him at a young age, is actually a world-renowned Hunter, a licensed professional who specializes in fantastical pursuits such as locating rare or unidentified animal species, treasure hunting, surveying unexplored enclaves, or hunting down lawless individuals. Gon departs on a journey to become a Hunter and eventually find his father. Along the way, Gon meets various other Hunters and encounters the paranormal.\\nHunter \u00d7 Hunter was adapted into a 62-episode anime television series produced by Nippon Animation and directed by Kazuhiro Furuhashi, which ran on Fuji Television from October 1999 to March 2001. Three separate original video animations (OVAs) totaling 30 episodes were subsequently produced by Nippon Animation and released in Japan from 2002 to 2004. A second anime television series by Madhouse aired on Nippon Television from October 2011 to September 2014, totaling 148 episodes, with two animated theatrical films released in 2013. There are also numerous audio albums, video games, musicals, and other media based on Hunter \u00d7 Hunter.\\nThe manga has been translated into English and released in North America by Viz Media since April 2005.

This is the simplest way to create a custom Agent. It is highly recommended that you work with the ZeroShotAgent, as at the moment that is by far the most generalizable one.\nMost of the work in creating the custom LLMChain comes down to the prompt. Because we are using an existing agent class to parse the output, it is very important that the prompt say to produce text in that format. Additionally, we currently require an agent_scratchpad input variable to put notes on previous actions and observations. This should almost always be the final part of the prompt. However, besides those instructions, you can customize the prompt as you wish.\nTo ensure that the prompt contains the appropriate instructions, we will utilize a helper method on that class. The helper method for the ZeroShotAgent takes the following arguments:\ntools: List of tools the agent will have access to, used to format the prompt.\nprefix: String to put before the list of tools.\nsuffix: String to put after the list of tools.", "source": "/content/https://python.langchain.com/en/latest/modules/agents/agents/custom_mrkl_agent.html"}

But many times you may want to get more structured information than just text back. This is where output parsers come in.\nOutput parsers are classes that help structure language model responses. There are two main methods an output parser must implement:\nget_format_instructions() -> str: A method which returns a string containing instructions for how the output of a language model should be formatted.\nparse(str) -> Any: A method which takes in a string (assumed to be the response from a language model) and parses it into some structure.\nAnd then one optional one:\nparse_with_prompt(str) -> Any: A method which takes in a string (assumed to be the response from a language model) and a prompt (assumed to the prompt that generated such a response) and parses it into some structure. The prompt is largely provided in the event the OutputParser wants to retry or fix the output in some way, and needs information from the prompt to do so.\nTo start, we recommend familiarizing yourself with the Getting Started section\nOutput Parsers\nAfter that, we provide deep dives on all the different types of output parsers.\nCommaSeparatedListOutputParser\nOutputFixingParser\nPydanticOutputParser\nRetryOutputParser\nStructured Output Parser\nprevious\nSimilarity ExampleSelector\nnext\nOutput Parsers\nBy Harrison Chase\n    \n      \u00a9 Copyright 2023, Harrison Chase.\n      \n  Last updated on Apr 26, 2023.", "source": "/content/https://python.langchain.com/en/latest/modules/prompts/output_parsers.html"}

For more on this, see here.\nThis concept is extremely relevant when considering putting LLM applications in production. In order to personalize LLM applications, you may want to combine LLMs with up-to-date information about particular users. Feature stores can be a great way to keep that data fresh, and LangChain provides an easy way to combine that data with LLMs.\nIn this notebook we will show how to connect prompt templates to feature stores. The basic idea is to call a feature store from inside a prompt template to retrieve values that are then formatted into the prompt.\nFeast#\nTo start, we will use the popular open source feature store framework Feast.\nThis assumes you have already run the steps in the README around getting started. We will build of off that example in getting started, and create and LLMChain to write a note to a specific driver regarding their up-to-date statistics.\nLoad Feast Store#\nAgain, this should be set up according to the instructions in the Feast README\nfrom feast import FeatureStore\n# You may need to update the path depending on where you stored it\nfeast_repo_path = \"../../../../../my_feature_repo/feature_repo/\"\nstore = FeatureStore(repo_path=feast_repo_path)\nPrompts#", "source": "/content/https://python.langchain.com/en/latest/modules/prompts/prompt_templates/examples/connecting_to_a_feature_store.html"}

To achieve this task, we will create a custom prompt template that takes in the function name as input, and formats the prompt template to provide the source code of the function.\nWhy are custom prompt templates needed?#\nLangChain provides a set of default prompt templates that can be used to generate prompts for a variety of tasks. However, there may be cases where the default prompt templates do not meet your needs. For example, you may want to create a prompt template with specific dynamic instructions for your language model. In such cases, you can create a custom prompt template.\nTake a look at the current set of default prompt templates here.\nCreating a Custom Prompt Template#\nThere are essentially two distinct prompt templates available - string prompt templates and chat prompt templates. String prompt templates provides a simple prompt in string format, while chat prompt templates produces a more structured prompt to be used with a chat API.\nIn this guide, we will create a custom prompt using a string prompt template.\nTo create a custom string prompt template, there are two requirements:\nIt has an input_variables attribute that exposes what input variables the prompt template expects.\nIt exposes a format method that takes in keyword arguments corresponding to the expected input_variables and returns the formatted prompt.\nWe will create a custom prompt template that takes in the function name as input and formats the prompt to provide the source code of the function.

This can make it easy to share, store, and version prompts. This notebook covers how to do that in LangChain, walking through all the different types of prompts and the different serialization options.\nAt a high level, the following design principles are applied to serialization:\nBoth JSON and YAML are supported. We want to support serialization methods that are human readable on disk, and YAML and JSON are two of the most popular methods for that. Note that this rule applies to prompts. For other assets, like Examples, different serialization methods may be supported.\nWe support specifying everything in one file, or storing different components (templates, examples, etc) in different files and referencing them. For some cases, storing everything in file makes the most sense, but for others it is preferrable to split up some of the assets (long templates, large examples, reusable components). LangChain supports both.\nThere is also a single entry point to load prompts from disk, making it easy to load any type of prompt.\n# All prompts are loaded through the `load_prompt` function.\nfrom langchain.prompts import load_prompt\nPromptTemplate#\nThis section covers examples for loading a PromptTemplate.\nLoading from YAML#", "source": "/content/https://python.langchain.com/en/latest/modules/prompts/prompt_templates/examples/prompt_serialization.html"}

+{"id": "205a63fa1c3a-0", "text": ".ipynb\n.pdf\nHow to work with partial Prompt Templates\n Contents \nPartial With Strings\nPartial With Functions\nHow to work with partial Prompt Templates#\nA prompt template is a class with a .format method which takes in a key-value map and returns a string (a prompt) to pass to the language model. Like other methods, it can make sense to \u201cpartial\u201d a prompt template - eg pass in a subset of the required values, as to create a new prompt template which expects only the remaining subset of values.\nLangChain supports this in two ways: we allow for partially formatted prompts (1) with string values, (2) with functions that return string values. These two different ways support different use cases. In the documentation below we go over the motivations for both use cases as well as how to do it in LangChain.\nPartial With Strings#\nOne common use case for wanting to partial a prompt template is if you get some of the variables before others. For example, suppose you have a prompt template that requires two variables, foo and baz. If you get the foo value early on in the chain, but the baz value later, it can be annoying to wait until you have both variables in the same place to pass them to the prompt template. Instead, you can partial the prompt template with the foo value, and then pass the partialed prompt template along and just use that. Below is an example of doing this:\nfrom langchain.prompts import PromptTemplate\nprompt = PromptTemplate(template=\"{foo}{bar}\", input_variables=[\"foo\", \"bar\"])\npartial_prompt = prompt.partial(foo=\"foo\");", "source": "/content/https://python.langchain.com/en/latest/modules/prompts/prompt_templates/examples/partial.html"}
+{"id": "205a63fa1c3a-1", "text": "partial_prompt = prompt.partial(foo=\"foo\");\nprint(partial_prompt.format(bar=\"baz\"))\nfoobaz\nYou can also just initialize the prompt with the partialed variables.\nprompt = PromptTemplate(template=\"{foo}{bar}\", input_variables=[\"bar\"], partial_variables={\"foo\": \"foo\"})\nprint(prompt.format(bar=\"baz\"))\nfoobaz\nPartial With Functions#\nThe other common use is to partial with a function. The use case for this is when you have a variable you know that you always want to fetch in a common way. A prime example of this is with date or time. Imagine you have a prompt which you always want to have the current date. You can\u2019t hard code it in the prompt, and passing it along with the other input variables is a bit annoying. In this case, it\u2019s very handy to be able to partial the prompt with a function that always returns the current date.\nfrom datetime import datetime\ndef _get_datetime():\n    now = datetime.now()\n    return now.strftime(\"%m/%d/%Y, %H:%M:%S\")\nprompt = PromptTemplate(\n    template=\"Tell me a {adjective} joke about the day {date}\", \n    input_variables=[\"adjective\", \"date\"]\n);\npartial_prompt = prompt.partial(date=_get_datetime)\nprint(partial_prompt.format(adjective=\"funny\"))\nTell me a funny joke about the day 02/27/2023, 22:15:16", "source": "/content/https://python.langchain.com/en/latest/modules/prompts/prompt_templates/examples/partial.html"}

This is where output parsers come in.\nOutput parsers are classes that help structure language model responses. There are two main methods an output parser must implement:\nget_format_instructions() -> str: A method which returns a string containing instructions for how the output of a language model should be formatted.\nparse(str) -> Any: A method which takes in a string (assumed to be the response from a language model) and parses it into some structure.\nAnd then one optional one:\nparse_with_prompt(str, PromptValue) -> Any: A method which takes in a string (assumed to be the response from a language model) and a prompt (assumed to the prompt that generated such a response) and parses it into some structure. The prompt is largely provided in the event the OutputParser wants to retry or fix the output in some way, and needs information from the prompt to do so.\nBelow we go over the main type of output parser, the PydanticOutputParser. See the examples folder for other options.\nfrom langchain.prompts import PromptTemplate, ChatPromptTemplate, HumanMessagePromptTemplate\nfrom langchain.llms import OpenAI\nfrom langchain.chat_models import ChatOpenAI\nfrom langchain.output_parsers import PydanticOutputParser\nfrom pydantic import BaseModel, Field, validator\nfrom typing import List\nmodel_name = 'text-davinci-003'\ntemperature = 0.0", "source": "/content/https://python.langchain.com/en/latest/modules/prompts/output_parsers/getting_started.html"}

In order to best understand what this means, it\u2019s worth highlighting what the base Retriever interface is. The BaseRetriever class in LangChain is as follows:\nfrom abc import ABC, abstractmethod\nfrom typing import List\nfrom langchain.schema import Document\nclass BaseRetriever(ABC):\n    @abstractmethod\n    def get_relevant_documents(self, query: str) -> List[Document]:\n        \"\"\"Get texts relevant for a query.\n        Args:\n            query: string to find relevant texts for\n        Returns:\n            List of relevant documents\n        \"\"\"\nIt\u2019s that simple! The get_relevant_documents method can be implemented however you see fit.\nOf course, we also help construct what we think useful Retrievers are. The main type of Retriever that we focus on is a Vectorstore retriever. We will focus on that for the rest of this guide.\nIn order to understand what a vectorstore retriever is, it\u2019s important to understand what a Vectorstore is. So let\u2019s look at that.\nBy default, LangChain uses Chroma as the vectorstore to index and search embeddings. To walk through this tutorial, we\u2019ll first need to install chromadb.\npip install chromadb\nThis example showcases question answering over documents.\nWe have chosen this as the example for getting started because it nicely combines a lot of different elements (Text splitters, embeddings, vectorstores) and then also shows how to use them in a chain.\nQuestion answering over documents consists of four steps:", "source": "/content/https://python.langchain.com/en/latest/modules/indexes/getting_started.html"}
+{"id": "61ad92cb255f-1", "text": "Question answering over documents consists of four steps:\nCreate an index\nCreate a Retriever from that index\nCreate a question answering chain\nAsk questions!\nEach of the steps has multiple sub steps and potential configurations. In this notebook we will primarily focus on (1). We will start by showing the one-liner for doing so, but then break down what is actually going on.\nFirst, let\u2019s import some common classes we\u2019ll use no matter what.\nfrom langchain.chains import RetrievalQA\nfrom langchain.llms import OpenAI\nNext in the generic setup, let\u2019s specify the document loader we want to use.

How is this index getting created?\nA lot of the magic is being hid in this VectorstoreIndexCreator. What is this doing?\nThere are three main steps going on after the documents are loaded:\nSplitting documents into chunks\nCreating embeddings for each document\nStoring documents and embeddings in a vectorstore\nLet\u2019s walk through this in code\ndocuments = loader.load()\nNext, we will split the documents into chunks.\nfrom langchain.text_splitter import CharacterTextSplitter\ntext_splitter = CharacterTextSplitter(chunk_size=1000, chunk_overlap=0)\ntexts = text_splitter.split_documents(documents)\nWe will then select which embeddings we want to use.\nfrom langchain.embeddings import OpenAIEmbeddings\nembeddings = OpenAIEmbeddings()\nWe now create the vectorstore to use as the index.\nfrom langchain.vectorstores import Chroma\ndb = Chroma.from_documents(texts, embeddings)\nRunning Chroma using direct local API.\nUsing DuckDB in-memory for database. Data will be transient.\nSo that\u2019s creating the index. Then, we expose this index in a retriever interface.\nretriever = db.as_retriever()\nThen, as before, we create a chain and use it to answer questions!", "source": "/content/https://python.langchain.com/en/latest/modules/indexes/getting_started.html"}

He said she is a consensus builder and has received a broad range of support from organizations such as the Fraternal Order of Police and former judges appointed by Democrats and Republicans.\"\nVectorstoreIndexCreator is just a wrapper around all this logic. It is configurable in the text splitter it uses, the embeddings it uses, and the vectorstore it uses. For example, you can configure it as below:\nindex_creator = VectorstoreIndexCreator(\n    vectorstore_cls=Chroma, \n    embedding=OpenAIEmbeddings(),\n    text_splitter=CharacterTextSplitter(chunk_size=1000, chunk_overlap=0)\n)\nHopefully this highlights what is going on under the hood of VectorstoreIndexCreator. While we think it\u2019s important to have a simple way to create indexes, we also think it\u2019s important to understand what\u2019s going on under the hood.\nprevious\nIndexes\nnext\nDocument Loaders\n Contents\n  \nOne Line Index Creation\nWalkthrough\nBy Harrison Chase\n    \n      \u00a9 Copyright 2023, Harrison Chase.\n      \n  Last updated on Apr 26, 2023.", "source": "/content/https://python.langchain.com/en/latest/modules/indexes/getting_started.html"}

It was a really old and very used VHS, I had no information about this movie, but I liked the references listed on its cover: the names of Peter Bogdanovich, Audrey Hepburn, John Ritter and specially Dorothy Stratten attracted me, the price was very low and I decided to risk and buy it. I searched IMDb, and the User Rating of 6.0 was an excellent reference. I looked in \"Mick Martin & Marsha Porter Video & DVD Guide 2003\" and \\x96 wow \\x96 four stars! So, I decided that I could not waste more time and immediately see it. Indeed, I have just finished watching \"They All Laughed\" and I found it a very boring overrated movie. The characters are badly developed, and I spent lots of minutes to understand their roles in the story. The plot is supposed to be funny (private eyes who fall in love for the women they are chasing), but I have not laughed along the whole story. The coincidences, in a huge city like New York, are ridiculous. Ben Gazarra as an attractive and very seductive man, with the women falling for him as if her were a Brad Pitt, Antonio Banderas or George Clooney, is quite ridiculous. In the end, the greater attractions certainly are the presence of the Playboy centerfold and playmate of the year Dorothy Stratten, murdered by her husband pretty after the release of this movie, and whose life was showed in \"Star 80\" and \"Death of a Centerfold: The Dorothy Stratten Story\"; the amazing beauty of the sexy Patti Hansen, the future Mrs. Keith Richards; the always wonderful, even being", "source": "/content/https://python.langchain.com/en/latest/modules/indexes/document_loaders/examples/hugging_face_dataset.html"}

We believe that the most powerful and differentiated applications will not only call out to a language model via an API, but will also:\\nBe data-aware: connect a language model to other sources of data\\nBe agentic: allow a language model to interact with its environment\\nThe LangChain framework is designed with the above principles in mind.\\nThis is the Python specific portion of the documentation. For a purely conceptual guide to LangChain, see here. For the JavaScript documentation, see here.\\nGetting Started\\nCheckout the below guide for a walkthrough of how to get started using LangChain to create an Language Model application.\\nGetting Started Documentation\\nModules\\nThere are several main modules that LangChain provides support for. For each module we provide some examples to get started, how-to guides, reference docs, and conceptual guides. These modules are, in increasing order of complexity:\\nModels: The various model types and model integrations LangChain supports.\\nPrompts: This includes prompt management, prompt optimization, and prompt serialization.\\nMemory: Memory is the concept of persisting state between calls of a chain/agent. LangChain provides a standard interface for memory, a collection of memory implementations, and examples of chains/agents that use memory.\\nIndexes: Language models are often more powerful when combined with your own text data - this module covers best practices for doing exactly that.\\nChains: Chains go beyond just a single LLM call, and are sequences of calls (whether to an LLM or a different utility).

LangChain provides a standard interface for chains, lots of integrations with other tools, and end-to-end chains for common applications.\\nAgents: Agents involve an LLM making decisions about which Actions to take, taking that Action, seeing an Observation, and repeating that until done. LangChain provides a standard interface for agents, a selection of agents to choose from, and examples of end to end agents.\\nUse Cases\\nThe above modules can be used in a variety of ways. LangChain also provides guidance and assistance in this. Below are some of the common use cases LangChain supports.\\nPersonal Assistants: The main LangChain use case. Personal assistants need to take actions, remember interactions, and have knowledge about your data.\\nQuestion Answering: The second big LangChain use case. Answering questions over specific documents, only utilizing the information in those documents to construct an answer.\\nChatbots: Since language models are good at producing text, that makes them ideal for creating chatbots.\\nQuerying Tabular Data: If you want to understand how to use LLMs to query data that is stored in a tabular format (csvs, SQL, dataframes, etc) you should read this page.\\nInteracting with APIs: Enabling LLMs to interact with APIs is extremely powerful in order to give them more up-to-date information and allow them to take actions.\\nExtraction: Extract structured information from text.\\nSummarization: Summarizing longer documents into shorter, more condensed chunks of information.

Fast strategies partition the document more quickly, but trade-off accuracy. Not all document types have separate hi res and fast partitioning strategies. For those document types, the strategy kwarg is ignored. In some cases, the high res strategy will fallback to fast if there is a dependency missing (i.e. a model for document partitioning).

Create a Notion Table Database#\nCreate a new table database in Notion. You can add any column to the database and they will be treated as metadata. For example you can add the following columns:\nTitle: set Title as the default property.\nCategories: A Multi-select property to store categories associated with the page.\nKeywords: A Multi-select property to store keywords associated with the page.\nAdd your content to the body of each page in the database. The NotionDBLoader will extract the content and metadata from these pages.\n2.

Personal assistants need to take actions, remember interactions, and have knowledge about your data.\\nQuestion Answering: The second big LangChain use case. Answering questions over specific documents, only utilizing the information in those documents to construct an answer.\\nChatbots: Since language models are good at producing text, that makes them ideal for creating chatbots.\\nQuerying Tabular Data: If you want to understand how to use LLMs to query data that is stored in a tabular", "source": "/content/https://python.langchain.com/en/latest/modules/indexes/document_loaders/examples/sitemap.html"}

We\u2019ll add an LLMChainExtractor, which will iterate over the initially returned documents and extract from each only the content that is relevant to the query.\nfrom langchain.llms import OpenAI", "source": "/content/https://python.langchain.com/en/latest/modules/indexes/retrievers/examples/contextual-compression.html"}

We will learn how to create a chain, add components to it, and run it.\nIn this tutorial, we will cover:\nUsing a simple LLM chain\nCreating sequential chains\nCreating a custom chain\nWhy do we need chains?#\nChains allow us to combine multiple components together to create a single, coherent application. For example, we can create a chain that takes user input, formats it with a PromptTemplate, and then passes the formatted response to an LLM. We can build more complex chains by combining multiple chains together, or by combining chains with other components.\nQuick start: Using LLMChain#\nThe LLMChain is a simple chain that takes in a prompt template, formats it with the user input and returns the response from an LLM.\nTo use the LLMChain, first create a prompt template.\nfrom langchain.prompts import PromptTemplate\nfrom langchain.llms import OpenAI\nllm = OpenAI(temperature=0.9)\nprompt = PromptTemplate(\n    input_variables=[\"product\"],\n    template=\"What is a good name for a company that makes {product}?\",\n)\nWe can now create a very simple chain that will take user input, format the prompt with it, and then send it to the LLM.\nfrom langchain.chains import LLMChain", "source": "/content/https://python.langchain.com/en/latest/modules/chains/getting_started.html"}
+{"id": "66d7e69b8479-1", "text": "from langchain.chains import LLMChain\nchain = LLMChain(llm=llm, prompt=prompt)\n# Run the chain only specifying the input variable.\nprint(chain.run(\"colorful socks\"))\nSockSplash!\nYou can use a chat model in an LLMChain as well:\nfrom langchain.chat_models import ChatOpenAI\nfrom langchain.prompts.chat import (\n    ChatPromptTemplate,\n    HumanMessagePromptTemplate,\n)\nhuman_message_prompt = HumanMessagePromptTemplate(\n        prompt=PromptTemplate(\n            template=\"What is a good name for a company that makes {product}?\",\n            input_variables=[\"product\"],\n        )\n    )\nchat_prompt_template = ChatPromptTemplate.from_messages([human_message_prompt])\nchat = ChatOpenAI(temperature=0.9)\nchain = LLMChain(llm=chat, prompt=chat_prompt_template)\nprint(chain.run(\"colorful socks\"))\nRainbow Sox Co.\nDifferent ways of calling chains#\nAll classes inherited from Chain offer a few ways of running chain logic. The most direct one is by using __call__:\nchat = ChatOpenAI(temperature=0)\nprompt_template = \"Tell me a {adjective} joke\"\nllm_chain = LLMChain(\n    llm=chat,\n    prompt=PromptTemplate.from_template(prompt_template)\n)\nllm_chain(inputs={\"adjective\":\"corny\"})\n{'adjective': 'corny',", "source": "/content/https://python.langchain.com/en/latest/modules/chains/getting_started.html"}
+{"id": "66d7e69b8479-2", "text": "{'adjective': 'corny',\n 'text': 'Why did the tomato turn red? Because it saw the salad dressing!'}\nBy default, __call__ returns both the input and output key values. You can configure it to only return output key values by setting return_only_outputs to True.\nllm_chain(\"corny\", return_only_outputs=True)\n{'text': 'Why did the tomato turn red? Because it saw the salad dressing!'}\nIf the Chain only outputs one output key (i.e. only has one element in its output_keys), you can  use run method. Note that run outputs a string instead of a dictionary.\n# llm_chain only has one output key, so we can use run\nllm_chain.output_keys\n['text']\nllm_chain.run({\"adjective\":\"corny\"})\n'Why did the tomato turn red? Because it saw the salad dressing!'\nIn the case of one input key, you can input the string directly without specifying the input mapping.\n# These two are equivalent\nllm_chain.run({\"adjective\":\"corny\"})\nllm_chain.run(\"corny\")\n# These two are also equivalent\nllm_chain(\"corny\")\nllm_chain({\"adjective\":\"corny\"})\n{'adjective': 'corny',\n 'text': 'Why did the tomato turn red?

See an example here.\nAdd memory to chains#", "source": "/content/https://python.langchain.com/en/latest/modules/chains/getting_started.html"}
+{"id": "66d7e69b8479-3", "text": "Add memory to chains#\nChain supports taking a BaseMemory object as its memory argument, allowing Chain object to persist data across multiple calls. In other words, it makes Chain a stateful object.\nfrom langchain.chains import ConversationChain\nfrom langchain.memory import ConversationBufferMemory\nconversation = ConversationChain(\n    llm=chat,\n    memory=ConversationBufferMemory()\n)\nconversation.run(\"Answer briefly. What are the first 3 colors of a rainbow?\")\n# -> The first three colors of a rainbow are red, orange, and yellow.\nconversation.run(\"And the next 4?\")\n# -> The next four colors of a rainbow are green, blue, indigo, and violet.\n'The next four colors of a rainbow are green, blue, indigo, and violet.'\nEssentially, BaseMemory defines an interface of how langchain stores memory. It allows reading of stored data through load_memory_variables method and storing new data through save_context method. You can learn more about it in Memory section.\nDebug Chain#\nIt can be hard to debug Chain object solely from its output as most Chain objects involve a fair amount of input prompt preprocessing and LLM output post-processing. Setting verbose to True will print out some internal states of the Chain object while it is being ran.\nconversation = ConversationChain(\n    llm=chat,\n    memory=ConversationBufferMemory(),\n    verbose=True\n)\nconversation.run(\"What is ChatGPT?\")\n> Entering new ConversationChain chain...\nPrompt after formatting:", "source": "/content/https://python.langchain.com/en/latest/modules/chains/getting_started.html"}

If the AI does not know the answer to a question, it truthfully says it does not know.\nCurrent conversation:\nHuman: What is ChatGPT?\nAI:\n> Finished chain.\n'ChatGPT is an AI language model developed by OpenAI. It is based on the GPT-3 architecture and is capable of generating human-like responses to text prompts. ChatGPT has been trained on a massive amount of text data and can understand and respond to a wide range of topics. It is often used for chatbots, virtual assistants, and other conversational AI applications.'\nCombine chains with the SequentialChain#\nThe next step after calling a language model is to make a series of calls to a language model. We can do this using sequential chains, which are chains that execute their links in a predefined order. Specifically, we will use the SimpleSequentialChain. This is the simplest type of a sequential chain, where each step has a single input/output, and the output of one step is the input to the next.\nIn this tutorial, our sequential chain will:\nFirst, create a company name for a product. We will reuse the LLMChain we\u2019d previously initialized to create this company name.\nThen, create a catchphrase for the product. We will initialize a new LLMChain to create this catchphrase, as shown below.\nsecond_prompt = PromptTemplate(\n    input_variables=[\"company_name\"],\n    template=\"Write a catchphrase for the following company: {company_name}\",\n)", "source": "/content/https://python.langchain.com/en/latest/modules/chains/getting_started.html"}

For this example, we will create a custom chain that concatenates the outputs of 2 LLMChains.\nIn order to create a custom chain:\nStart by subclassing the Chain class,\nFill out the input_keys and output_keys properties,\nAdd the _call method that shows how to execute the chain.\nThese steps are demonstrated in the example below:\nfrom langchain.chains import LLMChain\nfrom langchain.chains.base import Chain\nfrom typing import Dict, List\nclass ConcatenateChain(Chain):\n    chain_1: LLMChain\n    chain_2: LLMChain\n    @property\n    def input_keys(self) -> List[str]:\n        # Union of the input keys of the two chains.", "source": "/content/https://python.langchain.com/en/latest/modules/chains/getting_started.html"}

This is particularly useful when you want to take the output from one call and use it as the input to another.\nIn this notebook we will walk through some examples for how to do this, using sequential chains. Sequential chains are defined as a series of chains, called in deterministic order. There are two types of sequential chains:\nSimpleSequentialChain: The simplest form of sequential chains, where each step has a singular input/output, and the output of one step is the input to the next.\nSequentialChain: A more general form of sequential chains, allowing for multiple inputs/outputs.\nSimpleSequentialChain#\nIn this series of chains, each individual chain has a single input and a single output, and the output of one step is used as input to the next.\nLet\u2019s walk through a toy example of doing this, where the first chain takes in the title of an imaginary play and then generates a synopsis for that title, and the second chain takes in the synopsis of that play and generates an imaginary review for that play.\nfrom langchain.llms import OpenAI\nfrom langchain.chains import LLMChain\nfrom langchain.prompts import PromptTemplate\n# This is an LLMChain to write a synopsis given a title of a play.\nllm = OpenAI(temperature=.7)\ntemplate = \"\"\"You are a playwright.

It has a few distinct differences from the LLMCheckerChain, in that it doesn\u2019t have any assumtions to the format of the input text (or summary).\nAdditionally, as the LLMs like to hallucinate when fact checking or get confused by context, it is sometimes beneficial to run the checker multiple times.  It does this by feeding the rewritten \u201cTrue\u201d result back on itself, and checking the \u201cfacts\u201d for truth.  As you can see from the examples below, this can be very effective in arriving at a generally true body of text.\nYou can control the number of times the checker runs by setting the max_checks parameter.  The default is 2, but you can set it to 1 if you don\u2019t want any double-checking.\nfrom langchain.chains import LLMSummarizationCheckerChain\nfrom langchain.llms import OpenAI\nllm = OpenAI(temperature=0)\nchecker_chain = LLMSummarizationCheckerChain(llm=llm, verbose=True, max_checks=2)\ntext = \"\"\"\nYour 9-year old might like these recent discoveries made by The James Webb Space Telescope (JWST):\n\u2022 In 2023, The JWST spotted a number of galaxies nicknamed \"green peas.\" They were given this name because they are small, round, and green, like peas.", "source": "/content/https://python.langchain.com/en/latest/modules/chains/examples/llm_summarization_checker.html"}

Moderation chains are useful for detecting text that could be hateful, violent, etc. This can be useful to apply on both user input, but also on the output of a Language Model. Some API providers, like OpenAI, specifically prohibit you, or your end users, from generating some types of harmful content. To comply with this (and to just generally prevent your application from being harmful) you may often want to append a moderation chain to any LLMChains, in order to make sure any output the LLM generates is not harmful.\nIf the content passed into the moderation chain is harmful, there is not one best way to handle it, it probably depends on your application. Sometimes you may want to throw an error in the Chain (and have your application handle that). Other times, you may want to return something to the user explaining that the text was harmful. There could even be other ways to handle it! We will cover all these ways in this notebook.\nIn this notebook, we will show:\nHow to run any piece of text through a moderation chain.\nHow to append a Moderation chain to an LLMChain.\nfrom langchain.llms import OpenAI\nfrom langchain.chains import OpenAIModerationChain, SequentialChain, LLMChain, SimpleSequentialChain\nfrom langchain.prompts import PromptTemplate\nHow to use the moderation chain#", "source": "/content/https://python.langchain.com/en/latest/modules/chains/examples/moderation.html"}

The SQLDatabaseChain can therefore be used with any SQL dialect supported by SQLAlchemy, such as MS SQL, MySQL, MariaDB, PostgreSQL, Oracle SQL, and SQLite. Please refer to the SQLAlchemy documentation for more information about requirements for connecting to your database. For example, a connection to MySQL requires an appropriate connector such as PyMySQL. A URI for a MySQL connection might look like: mysql+pymysql://user:pass@some_mysql_db_address/db_name\nThis demonstration uses SQLite and the example Chinook database.\nTo set it up, follow the instructions on https://database.guide/2-sample-databases-sqlite/, placing the .db file in a notebooks folder at the root of this repository.\nfrom langchain import OpenAI, SQLDatabase, SQLDatabaseChain\ndb = SQLDatabase.from_uri(\"sqlite:///../../../../notebooks/Chinook.db\")\nllm = OpenAI(temperature=0)", "source": "/content/https://python.langchain.com/en/latest/modules/chains/examples/sqlite.html"}

By default, the HyDE class comes with some default prompts to use (see the paper for more details on them), but we can also create our own.\nfrom langchain.llms import OpenAI\nfrom langchain.embeddings import OpenAIEmbeddings\nfrom langchain.chains import LLMChain, HypotheticalDocumentEmbedder\nfrom langchain.prompts import PromptTemplate\nbase_embeddings = OpenAIEmbeddings()\nllm = OpenAI()\n# Load with `web_search` prompt\nembeddings = HypotheticalDocumentEmbedder.from_llm(llm, base_embeddings, \"web_search\")\n# Now we can use it as any embedding class!\nresult = embeddings.embed_query(\"Where is the Taj Mahal?\")\nMultiple generations#\nWe can also generate multiple documents and then combine the embeddings for those. By default, we combine those by taking the average. We can do this by changing the LLM we use to generate documents to return multiple things.\nmulti_llm = OpenAI(n=4, best_of=4)", "source": "/content/https://python.langchain.com/en/latest/modules/chains/index_examples/hyde.html"}
