📖 Introduction

XTuner is an efficient, flexible and full-featured toolkit for fine-tuning large models.

Efficient

• Support LLM, VLM pre-training / fine-tuning on almost all GPUs. XTuner is capable of fine-tuning 7B LLM on a single 8GB GPU, as well as multi-node fine-tuning of models exceeding 70B.
• Automatically dispatch high-performance operators such as FlashAttention and Triton kernels to increase training throughput.
• Compatible with DeepSpeed 🚀, easily utilizing a variety of ZeRO optimization techniques.

Flexible

• Support various LLMs (InternLM, Mixtral-8x7B, Llama 2, ChatGLM, Qwen, Baichuan, ...).
• Support VLM (LLaVA). The performance of LLaVA-InternLM2-20B is outstanding.
• Well-designed data pipeline, accommodating datasets in any format, including but not limited to open-source and custom formats.
• Support various training algorithms (QLoRA, LoRA, full-parameter fune-tune), allowing users to choose the most suitable solution for their requirements.

Full-featured

• Support continuous pre-training, instruction fine-tuning, and agent fine-tuning.
• Support chatting with large models with pre-defined templates.
• The output models can seamlessly integrate with deployment and server toolkit (LMDeploy), and large-scale evaluation toolkit (OpenCompass, VLMEvalKit).

🔥 Supports

🛠️ Quick Start

Installation

• It is recommended to build a Python-3.10 virtual environment using conda

  conda create --name xtuner-env python=3.10 -y
  conda activate xtuner-env

• Install XTuner via pip

  pip install -U xtuner

  or with DeepSpeed integration

  pip install -U 'xtuner[deepspeed]'

• Install XTuner from source

  git clone https://github.com/InternLM/xtuner.git
  cd xtuner
  pip install -e '.[all]'

Fine-tune

XTuner supports the efficient fine-tune (e.g., QLoRA) for LLMs. Dataset prepare guides can be found on dataset_prepare.md.

• Step 0, prepare the config. XTuner provides many ready-to-use configs and we can view all configs by

  xtuner list-cfg

  Or, if the provided configs cannot meet the requirements, please copy the provided config to the specified directory and make specific modifications by

  xtuner copy-cfg ${CONFIG_NAME} ${SAVE_PATH}
  vi ${SAVE_PATH}/${CONFIG_NAME}_copy.py

• Step 1, start fine-tuning.

  xtuner train ${CONFIG_NAME_OR_PATH}

  For example, we can start the QLoRA fine-tuning of InternLM2.5-Chat-7B with oasst1 dataset by

  # On a single GPU
  xtuner train internlm2_5_chat_7b_qlora_oasst1_e3 --deepspeed deepspeed_zero2
  # On multiple GPUs
  (DIST) NPROC_PER_NODE=${GPU_NUM} xtuner train internlm2_5_chat_7b_qlora_oasst1_e3 --deepspeed deepspeed_zero2
  (SLURM) srun ${SRUN_ARGS} xtuner train internlm2_5_chat_7b_qlora_oasst1_e3 --launcher slurm --deepspeed deepspeed_zero2

  • --deepspeed means using DeepSpeed 🚀 to optimize the training. XTuner comes with several integrated strategies including ZeRO-1, ZeRO-2, and ZeRO-3. If you wish to disable this feature, simply remove this argument.

  • For more examples, please see finetune.md.

• Step 2, convert the saved PTH model (if using DeepSpeed, it will be a directory) to Hugging Face model, by

  xtuner convert pth_to_hf ${CONFIG_NAME_OR_PATH} ${PTH} ${SAVE_PATH}

Chat

XTuner provides tools to chat with pretrained / fine-tuned LLMs.

xtuner chat ${NAME_OR_PATH_TO_LLM} --adapter {NAME_OR_PATH_TO_ADAPTER} [optional arguments]

For example, we can start the chat with InternLM2.5-Chat-7B :

xtuner chat internlm/internlm2_5-chat-7b --prompt-template internlm2_chat

For more examples, please see chat.md.

Deployment

• Step 0, merge the Hugging Face adapter to pretrained LLM, by

  xtuner convert merge \
    ${NAME_OR_PATH_TO_LLM} \
    ${NAME_OR_PATH_TO_ADAPTER} \
    ${SAVE_PATH} \
    --max-shard-size 2GB

• Step 1, deploy fine-tuned LLM with any other framework, such as LMDeploy 🚀.

  pip install lmdeploy
  python -m lmdeploy.pytorch.chat ${NAME_OR_PATH_TO_LLM} \
    --max_new_tokens 256 \
    --temperture 0.8 \
    --top_p 0.95 \
    --seed 0

  🔥 Seeking efficient inference with less GPU memory? Try 4-bit quantization from LMDeploy! For more details, see here.

Evaluation

• We recommend using OpenCompass, a comprehensive and systematic LLM evaluation library, which currently supports 50+ datasets with about 300,000 questions.
