Linux: AMD Radeon 9070XT : ComfyUI is starting and is trying to detect an nVidia GPU when I have installed all the AMD dependancies/setup.

[Core420]

Custom Node Testing

• [x] I have tried disabling custom nodes and the issue persists (see how to disable custom nodes if you need help)

Expected Behavior

for the backend to start so that the front end can start so that I can use the program

Actual Behavior

The backend system is showing errors that imply the system is not finding an nVidia GPU (Which is correct there is only an AMG 9070XT on the PC), however, the system does not load the AMD GPU systems - even though I have downloaded/installed all the AMD specific systems listed on the 'how to install' on the ComyUI GIT page.

Steps to Reproduce

starting the app with : python main.py

Other

before running ComyUI i have tried setting the following:

export ROCM_PATH=/opt/rocm export HCC_AMDGPU_TARGET=gfx1201 export HSA_OVERRIDE_GFX_VERSION=10.0.0

But the result was the same.

Side note: I am running CachyOS, which is an optimised rolling release of Arch Linux, all the CUDA/Pytorch etc libraries are fully up to date.
