How to Install ComfyUI on Arch Linux (AMD ROCm + Krita AI Plugin Setup Guide)

In this step-by-step guide, I show you how to install ComfyUI on Arch Linux (CachyOS) using Python 3.13, set up ROCm for AMD GPUs (RDNA2/RDNA3), and fully integrate it with the Krita AI Diffusion plugin.

ComfyUI AMDGPU Arch linux install

sudo pacman -S wget git
yay python312
sudo pacman -S python-pip
sudo usermod -aG render,video shane
Reboot

Create Comfy folder for venv
Open terminal in new folder or use cd Comfy
python3.13 -m venv venv
In Same Folder Clone ComfyUI
git clone https://github.com/comfyanonymous/ComfyUI.git

source venv/bin/activate
pip install update pip
pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/rocm7.1

cd Comfyui
pip install -r requirements.txt

Using below command enables experimental memory efficient attention on pytorch2.5 for RDNA3
TORCH_ROCM_AOTRITON_ENABLE_EXPERIMENTAL=1 python main.py --use-pytorch-cross-attention

Install ComfyUI Manager
cd custom_nodes
git clone https://github.com/ltdrdata/ComfyUI-Manager comfyui-manager
Restart ComfyUI

Krita AI Plugin: https://github.com/Acly/krita-ai-diffusion

This setup works with AMD GPUs (RDNA 1, RDNA 2, RDNA 3 — with notes about current ROCm issues).

⚠️ Note: AMD + ROCm can be hit or miss depending on distro and version. I mention some current stability issues and possible workarounds in the video.
