ComfyUI Installer

Easily install ComfyUI (in a python venv) on Linux. Tested on Arch + AMD GPU.

Note: This is not the official ComfyUI icon.

Quick Start

You will need to have python, pyenv and pip on your system. Make sure to install for your GPU Vendor (AMD/Nvidia):

git clone https://github.com/HAMM3REXTREME/ComfyUI-Installer
cd ComfyUI-Installer
./install-amd.sh or ./install-nvidia.sh
./menu-entry.sh # Optionally add menu entry
./launch.sh

Installation

1. To install ComfyUI using this script, clone this repo and cd into it:
   git clone https://github.com/HAMM3REXTREME/ComfyUI-Installer && cd ComfyUI-Installer

2. After that's done, run the install script for your GPU vendor (AMD or Nvidia). This might take a while.
   To install for AMD: ./install-amd.sh
   To install for Nvidia: ./install-nvidia.sh
   Tip: You can optionally run ./menu-entry.sh in order to make a desktop menu entry.

3. When the install script has finished, you just need to copy/paste your models into their proper directories:
   Put your SD checkpoints (the huge ckpt/safetensors files) in: ComfyUI/models/checkpoints
   Put your VAE in: ComfyUI/models/vae

Once you've done that, launch ComfyUI using: ./launch.sh

Updating

Updating ComfyUI

Simply cd into the ComfyUI folder and run git pull:
cd ComfyUI && git pull

Upgrading python venv packages

Make sure to check out the actual ComfyUI repo for the most up to date information.

1. Run source venv/bin/activate to activate the Python virtual environment.
   (The installer creates a python venv named 'venv' in the base folder by default)

2. Upgrade torch, use the command for your GPU vendor (similar to the install script):
   For AMD: pip install --upgrade torch torchvision torchaudio --index-url https://download.pytorch.org/whl/rocm6.2
   For Nvidia: pip install --upgrade torch torchvision torchaudio --extra-index-url https://download.pytorch.org/whl/cu124
   Some version numbers might be out of date here.

3. Upgrade ComfyUI dependencies by running this command:
   pip install --upgrade -r ComfyUI/requirements.txt

After this you should have everything updated and can proceed to running ComfyUI.

Troubleshooting

If you get the "Torch not compiled with CUDA enabled" error

Uninstall torch with:

pip uninstall torch

And install it again with the command (for Nvidia) above.

For AMD cards not officially supported by ROCm

Try running it with this command if you have issues:

For 6700, 6600 and maybe other RDNA2 or older: HSA_OVERRIDE_GFX_VERSION=10.3.0 python main.py

For AMD 7600 and maybe other RDNA3 cards: HSA_OVERRIDE_GFX_VERSION=11.0.0 python main.py

You can add these changes (and other args you want) to launch.sh for convenience.
