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

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.

Docker image:

Remember to use ASCEND_RT_VISIBLE_DEVICES instead of CUDA_VISIBLE_DEVICES to specify the device to use.

If you cannot infer model on NPU devices, try setting do_sample: false in the configurations.

Data Preparation

Please refer to data/README.md for checking the details about the format of dataset files. You can either use datasets on HuggingFace / ModelScope hub or load the dataset in local disk.

Note

Please update data/dataset_info.json to use your custom dataset.

Quickstart

Use the following 3 commands to run LoRA fine-tuning, inference and merging of the Llama3-8B-Instruct model, respectively.

llamafactory-cli train examples/train_lora/llama3_lora_sft.yaml
llamafactory-cli chat examples/inference/llama3_lora_sft.yaml
llamafactory-cli export examples/merge_lora/llama3_lora_sft.yaml

See examples/README.md for advanced usage (including distributed training).

Tip

Use llamafactory-cli help to show help information.

Build Docker

Use Docker

docker build -f ./Dockerfile \
    --build-arg INSTALL_BNB=false \
    --build-arg INSTALL_VLLM=false \
    --build-arg INSTALL_DEEPSPEED=false \
    --build-arg PIP_INDEX=https://pypi.org/simple \

    -v ./data:/app/data \
    -v ./output:/app/output \
    -p 7860:7860 \
    -p 8000:8000 \
    --shm-size 16G \
    --name llamafactory \
    llamafactory:latest

Use Docker Compose

docker-compose up -d
docker-compose exec llamafactory bash
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.

Deploy with OpenAI-style API and vLLM

API_PORT=8000 llamafactory-cli api examples/inference/llama3_vllm.yaml

Tip

Visit https://platform.openai.com/docs/api-reference/chat/create for API document.

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.

Use W&B Logger

To use Weights & Biases for logging experimental results, you need to add the following arguments.

report_to: wandb
run_name: test_run # optional

Set WANDB_API_KEY to your key when launching training tasks to log in with your W&B account.
