## Style-Instruct Mistral 7B
Mistral 7B instruct fine-tuned on the [neuralwork/fashion-style-instruct](https://huggingface.co/datasets/neuralwork/fashion-style-instruct) dataset with LoRA and 4bit quantization. See the blog [post](https://blog.neuralwork.ai/an-llm-fine-tuning-cookbook-with-mistral-7b/) and Github [repository](https://github.com/neuralwork/instruct-finetune-mistral)
for training details. This model is trained with body type / personal style descriptions as input, target events (e.g. casual date, business meeting) as context and outfit combination suggestions as output. For a full list of event types, refer to the gradio demo [file](https://github.com/neuralwork/instruct-finetune-mistral/blob/main/app.py) in the Github repository.


## Usage
This repo contains the LoRA parameters of the fine-tuned Mistral 7B model. To perform inference, load and use the model as follows:

```
import torch
from peft import AutoPeftModelForCausalLM
from transformers import AutoTokenizer, AutoModelForCausalLM, BitsAndBytesConfig


def format_instruction(input, event):
    return f"""You are a personal stylist recommending fashion advice and clothing combinations. Use the self body and style description below, combined with the event described in the context to generate 5 self-contained and complete outfit combinations.
        ### Input:
        {input}

        ### Context:
        I'm going to a {event}.

        ### Response:
    """

# input is a self description of your body type and personal style
prompt = "I'm an athletic and 171cm tall woman in my mid twenties, I have a rectangle shaped body with slightly broad shoulders and have a sleek, casual style. I usually prefer darker colors."
event = "business meeting"
prompt = format_instruction(prompt, event)

# load base LLM model, LoRA params and tokenizer
model = AutoPeftModelForCausalLM.from_pretrained(
    "neuralwork/mistral-7b-style-instruct",
    low_cpu_mem_usage=True,
    torch_dtype=torch.float16,
    load_in_4bit=True,
)
tokenizer = AutoTokenizer.from_pretrained("neuralwork/mistral-7b-style-instruct")
input_ids = tokenizer(prompt, return_tensors="pt", truncation=True).input_ids.cuda()

# inference
with torch.inference_mode():
    outputs = model.generate(
        input_ids=input_ids, 
        max_new_tokens=800, 
        do_sample=True, 
        top_p=0.9,
        temperature=0.9
    )

# decode output tokens and strip response
outputs = outputs.detach().cpu().numpy()
outputs = tokenizer.batch_decode(outputs, skip_special_tokens=True)
output = outputs[0][len(prompt):]
