I have a Radeon 6900 XT and couldn't get the the regular ComfyUI (both desktop app and portable install) to work.
Gemini recommended ComfyUI-ZLUDA and I was able to get it running after much trial and error.
Here are the biggest tips:
-
The instructions say to get
Python 3.11.9 or higher (3.12 is a minimum for using Triton)but Python 3.14 didn't work. It would fail to download torch-2.7.0. I had to install Python 3.12 using the installer. The embeddable package is missing some libraries. -
It says to install
Visual Studio Build Toolsbut it doesn't say which options to include. An error message later in the script will tell you to includeDesktop development with C++. -
If any
