This project is a tutorial on parameter-efficient fine-tuning (PEFT) and quantization of the Mistral 7B v0.1 model. We use LoRA for PEFT and 4-bit quantization to compress the model, and fine-tune the model on a semi-manually crafted fashion style recommendation instruct dataset. For more information and a step by step guide, see our blog post.
Start by cloning the repository, setting up a conda environment and installing the dependencies. We tested our scripts with python 3.9 and CUDA 11.7.
git clone https://github.com/neuralwork/finetune-mistral.git
cd finetune-mistral
conda create -n llm python=3.9
conda activate llm
pip install -r requirements.txt
You can finetune the model on our fashion-style-instruct dataset or another dataset. Note that you will need to have the same features as our dataset and pass in your HF Hub token as an argument if using a private dataset. Fine-tuning takes about 2 hours on a single A40, you can either use the default accelerate settings or configure it to use multiple GPUS. To fine-tune the model:
accelerate config default
python finetune_model.py --dataset=<HF_DATASET_ID_OR_PATH> --base_model="mistralai/Mistral-7B-v0.1" --model_name=<YOUR_MODEL_NAME> --auth_token=<HF_AUTH_TOKEN> --push_to_hub
One model training is completed, only the fine-tuned (LoRA) parameters are saved, which are loaded to overwrite the corresponding parameters of the base model during testing.
To test the fine-tuned model with a random sample selected from the dataset, run python test.py. To launch the full Gradio demo and play around with your own examples, launch the demo with python app.py
