LLaMA Efficient Tuning
👋 Join our WeChat.
Changelog
[23/06/22] Now we align the demo API with the OpenAI's format where you can insert the fine-tuned model in arbitrary ChatGPT-based applications.
[23/06/15] Now we support training the baichuan-7B model in this repo. Try --model_name_or_path baichuan-inc/baichuan-7B and --lora_target W_pack arguments to use the baichuan-7B model.
[23/06/03] Now we support quantized training and inference (aka QLoRA). Try --quantization_bit 4/8 argument to work with quantized model. (experimental feature)
[23/05/31] Now we support training the BLOOM & BLOOMZ models in this repo. Try --model_name_or_path bigscience/bloomz-7b1-mt and --lora_target query_key_value arguments to use the BLOOMZ model.
Supported Models
Supported Training Approaches
Provided Datasets
- For pre-training:
- For supervised fine-tuning:
- For reward model training:
Please refer to data/README.md for details.
Some datasets require confirmation before using them, so we recommend logging in with your HuggingFace account using these commands.
pip install --upgrade huggingface_hub
huggingface-cli login
Requirement
- Python 3.8+ and PyTorch 1.13.1+
- 🤗Transformers, Datasets, Accelerate, PEFT and TRL
- jieba, rouge_chinese and nltk (used at evaluation)
- gradio and mdtex2html (used in web_demo.py)
- uvicorn and fastapi (used in api_demo.py)
And powerful GPUs!
Getting Started
Data Preparation (optional)
Please refer to data/example_dataset for checking the details about the format of dataset files. You can either use a single .json file or a dataset loading script with multiple files to create a custom dataset.
Note: please update data/dataset_info.json to use your custom dataset. About the format of this file, please refer to data/README.md.
Dependence Installation (optional)
git clone https://github.com/hiyouga/LLaMA-Efficient-Tuning.git
conda create -n llama_etuning python=3.10
conda activate llama_etuning
cd LLaMA-Efficient-Tuning
pip install -r requirements.txt
LLaMA Weights Preparation (optional)
- Download the weights of the LLaMA models.
- Convert them to HF format using the following command.
python -m transformers.models.llama.convert_llama_weights_to_hf \
--input_dir path_to_llama_weights --model_size 7B --output_dir path_to_llama_model
