Docker Setup for NVIDIA GPUs

This directory contains Docker configuration files for running LLaMA Factory with NVIDIA GPU support.

Prerequisites

Linux-specific Requirements

Before running the Docker container with GPU support, you need to install the following packages:

1. Docker: The container runtime

   bashCopy

   # Ubuntu/Debian
   sudo apt-get update
   sudo apt-get install docker.io
   
   # Or install Docker Engine from the official repository:
   # https://docs.docker.com/engine/install/
   

2. Docker Compose (if using the docker-compose method):

   bashCopy

   # Ubuntu/Debian
   sudo apt-get install docker-compose
   
   # Or install the latest version:
   # https://docs.docker.com/compose/install/
   

3. NVIDIA Container Toolkit (required for GPU support):

   bashCopy

   # Add the NVIDIA GPG key and repository
   distribution=$(. /etc/os-release;echo $ID$VERSION_ID)
   curl -s -L https://nvidia.github.io/nvidia-docker/gpgkey | sudo apt-key add -
   curl -s -L https://nvidia.github.io/nvidia-docker/$distribution/nvidia-docker.list | sudo tee /etc/apt/sources.list.d/nvidia-docker.list
   
   # Install nvidia-container-toolkit
   sudo apt-get update
   sudo apt-get install -y nvidia-container-toolkit
   
   # Restart Docker to apply changes
   sudo systemctl restart docker
   

   Note: Without nvidia-container-toolkit, the Docker container will not be able to access your NVIDIA GPU.

Verify GPU Access

After installation, verify that Docker can access your GPU:

sudo docker run --rm --gpus all nvidia/cuda:12.4.0-base-ubuntu22.04 nvidia-smi

If successful, you should see your GPU information displayed.

Usage

Using Docker Compose (Recommended)

cd docker/docker-cuda/
docker compose up -d
docker compose exec llamafactory bash

Using Docker Run

# Build the image
docker build -f ./docker/docker-cuda/Dockerfile \
    --build-arg PIP_INDEX=https://pypi.org/simple \
    --build-arg EXTRAS=metrics \
    -t llamafactory:latest .

# Run the container
docker run -dit --ipc=host --gpus=all \
    -p 7860:7860 \
    -p 8000:8000 \
    --name llamafactory \
    llamafactory:latest

# Enter the container
docker exec -it llamafactory bash

Troubleshooting

GPU Not Detected

If your GPU is not detected inside the container:

1. Ensure nvidia-container-toolkit is installed
2. Check that the Docker daemon has been restarted after installation
3. Verify your NVIDIA drivers are properly installed: nvidia-smi
4. Check Docker GPU support: docker run --rm --gpus all ubuntu nvidia-smi

Permission Denied

If you get permission errors, ensure your user is in the docker group:

sudo usermod -aG docker $USER
# Log out and back in for changes to take effect

Additional Notes

• The default image is built on Ubuntu 22.04 (x86_64), CUDA 12.4, Python 3.11, PyTorch 2.6.0, and Flash-attn 2.7.4
• For different CUDA versions, you may need to adjust the base image in the Dockerfile
• Make sure your NVIDIA driver version is compatible with the CUDA version used in the Docker image
