# bitsandbytes

I needed to get bitsandbytes working in my venv:
I replaced the main.py in C:\Users\user\Desktop\test\peft\venv\Lib\site-packages\bitsandbytes\cuda_setup\main.py with the one here!
I also added a .dll file here: C:\Users\user\Desktop\test\peft\venv\Lib\site-packages\bitsandbytes\libbitsandbytes_cuda116.dll

This output is like the training data. If you run without applying the Lora, it will usually look worse. If you retrain the lora, know that your new lora is not going to output the same results, despite you using the same settings.
Inference should usually be deterministic when using the same lora, or using without lora.




Also, If you want to download and use the loras from a visible folder, here's the inference script:

```
import torch
from peft import PeftModel, PeftConfig
from transformers import AutoModelForCausalLM, AutoTokenizer

peft_model_id = "./loramodel"
config = PeftConfig.from_pretrained(peft_model_id)
model = AutoModelForCausalLM.from_pretrained(config.base_model_name_or_path, return_dict=True, load_in_8bit=True, device_map='auto')
tokenizer = AutoTokenizer.from_pretrained(config.base_model_name_or_path)

# Load the Lora model
model = PeftModel.from_pretrained(model, peft_model_id)


batch = tokenizer("Two things are infinite: ", return_tensors='pt')

with torch.cuda.amp.autocast():
  output_tokens = model.generate(**batch, max_new_tokens=50)

print('\n\n', tokenizer.decode(output_tokens[0], skip_special_tokens=True))
```

add your adapter_config.json and your adapter_model.bin to a folder in your current directory named `loramodel`, or whatever you choose.
