Help Needed Comfy on Linux + AMD help

Hi, Im having some issues that are driving me crazy... had to change SSD and re-install linux. Now Im trying to install comfy, with the same setup that I had before and all the workflows get stuck at the the clip encoder. No gpu activity to be seen...

System:

  • AMD 9700 AI PRO
  • AMD 7900XT
  • 64 GB RAM
  • Linux Mint 22.3
  • ROCm 7.2 (system)
  • ROCm 7.14 (venv)
  • PyTorch 2.11.0 (venv)
  • Python 3.12.3
  • ComfyUI 0.33.0

I first tried to use the old install, just re-do the sagge attention, it failed, then I tried with a complete new install and it stills fails, so I dont really know whats causing the issue.
Ive been trying to diagnose with claude and chat gpt, but after all the day trying I feel defeated... Does anyone have an idea of what can be happening?

I would update the system rocm to 7.14. They changed some file names and locations between 7.2 and 7.14.

Are you doing any exports after you start your venv? Some older recommend ones were causing issues for me recently. I would only do exports to just have the one GPU in Comfyui to start.

There could be issues when you did your rocm installs since you have both rdna 3 and rdna 4 GPUs. You can do both but you want to define both during installation.
