Create an isolated Python environment with uv:

uv run llamafactory-cli webui

Install PyTorch

You need to manually install the GPU version of PyTorch on the Windows platform. Please refer to the official website and the following command to install PyTorch with CUDA support:

pip uninstall torch torchvision torchaudio
pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu126
python -c "import torch; print(torch.cuda.is_available())"

If you see True then you have successfully installed PyTorch with CUDA support.

Try dataloader_num_workers: 0 if you encounter Can't pickle local object error.

Install BitsAndBytes

To enable Quantized LoRA (QLoRA) on Windows, you need to install bitsandbytes.

For most users, it is recommended to install the latest official release:

pip install bitsandbytes

If you are using uv to manage your virtual environment, it is recommended to install bitsandbytes after installing the GPU-enabled version of PyTorch:

uv pip install bitsandbytes --no-deps

[!IMPORTANT] Pay attention to the CUDA Toolkit version when installing bitsandbytes. Official bitsandbytes releases are built for specific CUDA Toolkit versions. On Windows x86-64, separate builds are currently provided for CUDA 11.8–12.6 and CUDA 12.8–12.9. Support for NVIDIA RTX 50 Series GPUs (e.g., RTX 5060 Ti, sm_120) requires the CUDA 12.8–12.9 builds.

If your environment uses an older CUDA version, or you need compatibility with older Windows / PyTorch combinations, you can install the third-party precompiled Windows wheel:

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

Install Flash Attention-2

To enable FlashAttention-2 on the Windows platform, please use the script from flash-attention-windows-wheel to compile and install it by yourself.

To install LlamaFactory on Ascend NPU devices, please use Python 3.12 and install the extra dependencies with pip install -r requirements/npu.txt. Additionally, you need to install the Ascend CANN Toolkit and Kernels. Please follow the installation tutorial.

You can also download the pre-built Docker images:

# Docker Hub

docker pull quay.io/ascend/llamafactory:latest-a3-openeuler

Install BitsAndBytes

To use QLoRA based on bitsandbytes on Ascend NPU, please follow these 3 steps:

1. Manually compile bitsandbytes: Refer to the installation documentation for the NPU version of bitsandbytes to complete the compilation and installation. The compilation requires a cmake version of at least 3.22.1 and a g++ version of at least 12.x.

# Install bitsandbytes from source
# Clone bitsandbytes repo, Ascend NPU backend is currently enabled on multi-backend-refactor branch
git clone -b multi-backend-refactor https://github.com/bitsandbytes-foundation/bitsandbytes.git
cd bitsandbytes/

# Install dependencies
pip install -r requirements-dev.txt

# Install the dependencies for the compilation tools. Note that the commands for this step may vary depending on the operating system. The following are provided for reference
apt-get install -y build-essential cmake

# Compile & install
cmake -DCOMPUTE_BACKEND=npu -S .
make
pip install .

1. Install transformers from the main branch.

git clone -b main https://github.com/huggingface/transformers.git
cd transformers
pip install .

1. Set double_quantization: false in the configuration. You can refer to the example.

You can uncomment VOLUME [ "/root/.cache/huggingface", "/app/shared_data", "/app/output" ] in the Dockerfile to use data volumes.

When building the Docker image, use -v ./hf_cache:/root/.cache/huggingface argument to mount the local directory to the container. The following data volumes are available.

• hf_cache: Utilize Hugging Face cache on the host machine.
• shared_data: The directionary to store datasets on the host machine.
• output: Set export dir to this location so that the merged result can be accessed directly on the host machine.
