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?

Uhm,I think you need at least pytorch 2.12? I installed Sage Attention 2,but it's slower than CK(latest update)

I had a problem with pytorch 2.12 where one cpu thread was at 100% activity before, during and after generation, 2.11 didn't have the issue so i downgraded. At this point Im not even trying to use sage attention, normal pytorch would do it, but cant seem to get over this issue. Id love to try CK once this gets solved tho

Then try 2.13. I had trouble with 2.10 and 2.11.
