Features

  • Various models: LLaMA, Mistral, Mixtral-MoE, Qwen, Yi, Gemma, Baichuan, ChatGLM, Phi, etc.
  • Integrated methods: (Continuous) pre-training, supervised fine-tuning, reward modeling, PPO, DPO and ORPO.
  • Scalable resources: 32-bit full-tuning, 16-bit freeze-tuning, 16-bit LoRA and 2/4/8-bit QLoRA via AQLM/AWQ/GPTQ/LLM.int8.
  • Advanced algorithms: GaLore, BAdam, DoRA, LongLoRA, LLaMA Pro, Mixture-of-Depths, LoRA+, LoftQ and Agent tuning.
  • Practical tricks: FlashAttention-2, Unsloth, RoPE scaling, NEFTune and rsLoRA.
  • Experiment monitors: LlamaBoard, TensorBoard, Wandb, MLflow, etc.
  • Faster inference: OpenAI-style API, Gradio UI and CLI with vLLM worker.

Benchmark

Compared to ChatGLM's P-Tuning, LLaMA Factory's LoRA tuning offers up to 3.7 times faster training speed with a better Rouge score on the advertising text generation task. By leveraging 4-bit quantization technique, LLaMA Factory's QLoRA further improves the efficiency regarding the GPU memory.

benchmark

Definitions
  • Training Speed: the number of training samples processed per second during the training. (bs=4, cutoff_len=1024)
  • Rouge Score: Rouge-2 score on the development set of the advertising text generation task. (bs=4, cutoff_len=1024)
  • GPU Memory: Peak GPU memory usage in 4-bit quantized training. (bs=1, cutoff_len=1024)
  • We adopt pre_seq_len=128 for ChatGLM's P-Tuning and lora_rank=32 for LLaMA Factory's LoRA tuning.

Note

Default module is used for the --lora_target argument, you can use --lora_target all to specify all the available modules for better convergence.

For the "base" models, the --template argument can be chosen from default, alpaca, vicuna etc. But make sure to use the corresponding template for the "instruct/chat" models.

Remember to use the SAME template in training and inference.

Please refer to constants.py for a full list of models we supported.

You also can add a custom chat template to template.py.

Dependence Installation

git clone https://github.com/hiyouga/LLaMA-Factory.git
conda create -n llama_factory python=3.10
conda activate llama_factory
cd LLaMA-Factory
pip install -e .[metrics]

Extra dependencies available: deepspeed, metrics, unsloth, galore, badam, vllm, bitsandbytes, gptq, awq, aqlm, qwen, modelscope, quality

For Windows users

If you want to enable the quantized LoRA (QLoRA) on the Windows platform, you will be required to install a pre-built version of bitsandbytes library, which supports CUDA 11.1 to 12.2, please select the appropriate release version based on your CUDA version.

pip install https://github.com/jllllll/bitsandbytes-windows-webui/releases/download/wheels/bitsandbytes-0.41.2.post2-py3-none-win_amd64.whl

To enable FlashAttention-2 on the Windows platform, you need to install the precompiled flash-attn library, which supports CUDA 12.1 to 12.2. Please download the corresponding version from flash-attention based on your requirements.

Train with LLaMA Board GUI (powered by Gradio)

Important

LLaMA Board GUI only supports training on a single GPU, please use CLI for distributed training.

Use local environment

export CUDA_VISIBLE_DEVICES=0 # `set CUDA_VISIBLE_DEVICES=0` for Windows
export GRADIO_SERVER_PORT=7860 # `set GRADIO_SERVER_PORT=7860` for Windows
python src/train_web.py # or python -m llmtuner.webui.interface
For Alibaba Cloud users

If you encountered display problems in LLaMA Board on Alibaba Cloud, try using the following command to set environment variables before starting LLaMA Board:

export GRADIO_ROOT_PATH=/${JUPYTER_NAME}/proxy/7860/

Use Docker

docker build -f ./Dockerfile -t llama-factory:latest .
docker run --gpus=all \
    -v ./hf_cache:/root/.cache/huggingface/ \
    -v ./data:/app/data \
    -v ./output:/app/output \
    -e CUDA_VISIBLE_DEVICES=0 \
    -p 7860:7860 \
    --shm-size 16G \
    --name llama_factory \
    -d llama-factory:latest

Use Docker Compose

docker compose -f ./docker-compose.yml up -d
Details about volume
  • hf_cache: Utilize Hugging Face cache on the host machine. Reassignable if a cache already exists in a different directory.
  • data: Place datasets on this dir of the host machine so that they can be selected on LLaMA Board GUI.
  • output: Set export dir to this location so that the merged result can be accessed directly on the host machine.

Train with Command Line Interface

See examples/README.md for usage.

Use python src/train_bash.py -h to display arguments description.

Deploy with OpenAI-style API and vLLM

CUDA_VISIBLE_DEVICES=0,1 API_PORT=8000 python src/api_demo.py \
    --model_name_or_path meta-llama/Meta-Llama-3-8B-Instruct \
    --template llama3 \
    --infer_backend vllm \
    --vllm_enforce_eager

Download from ModelScope Hub

If you have trouble with downloading models and datasets from Hugging Face, you can use ModelScope.

export USE_MODELSCOPE_HUB=1 # `set USE_MODELSCOPE_HUB=1` for Windows

Train the model by specifying a model ID of the ModelScope Hub as the --model_name_or_path. You can find a full list of model IDs at ModelScope Hub, e.g., LLM-Research/Meta-Llama-3-8B-Instruct.
