Install ComfyUI

Install ComfyUI#

Install ComfyUI on AMD GPUs.

Prerequisites#

  • ROCm is installed.

Installation#

Follow these steps to install ComfyUI.

  1. Install the Python venv package for the applicable Python version.

    sudo apt install python3.12-venv

  2. Create a Python virtual environment.

    python3 -m venv comfyui-venv
source comfyui-venv/bin/activate

  3. Install the latest PyTorch ROCm wheels in the environment created.

    Note
    Refer to Install Pytorch for Ryzen APUs for more comprehensive install instructions. Proceed to install within the environment if the wheels are already downloaded to the system. Example command:

    pip3 install <torch wheel> <torchaudio wheel> <torchvision wheel> <triton wheel>

  4. Clone the ComfyUI repository.

    git clone https://github.com/comfyanonymous/ComfyUI.git

    Note

    See ComfyUI Github for more information.

  5. Install ComfyUI requirements.

    pip install -r requirements.txt

  6. Load Stable Diffusion 3 model into the following folder.

    cd ComfyUI/models/checkpoints

    Note

    As an example, the sd3_medium_incl_clips.safetensors model can be added into this directory.
    This version already includes the clips, so only this download is needed. You may need to sign in and request access to the model

  7. Launch ComfyUI.

    Note

    Users must return to the home directory of the repository in order to run main.py.

    python3 main.py

    Note
    After running the above command, ensure that the Pytorch version seen in the terminal is the ROCm 6.4.4 specific one.

Example usage#

From the ComfyUI frontend, navigate to templates → Basic → Image Generation. Toggle to your downloaded model (ex. sd3_medium_incl_clips.safetensors) within the ‘Load Checkpoint’ node. PyTorch template
