RuntimeError: Found no NVIDIA driver on your system. (AMD Linux, was working minutes ago)

realsetvin commented 2 months ago

Expected Behavior

using amd on linux, was working just fine minutes ago

Actual Behavior

after following a guide to install something needed for another product on linux, I can no longer run comfyui. I have tried to redownload, ext. Searched fruitlessly everywhere. Really need help to resolve this extremely frustrating issue.

Steps to Reproduce

Issue occurred directly after following the linux version of this guide https://huggingface.co/docs/bitsandbytes/main/en/installation#multi-backend

NVIDIA CUDA is required to run pytorch which is needed for Comfy UI. CUDA technology is exclusive to NVIDIA, and it's not directly compatible with AMD GPU.

Run this command to make sure nvidia-smi

For AMD, there are are ways to use NVIDIA on your linux machine though, but I've never tried it but you can find some guides on it online

Probably installation of bitsandbytes installed non-rocm pytorch. Can you run the following commands to verify that?

rocminfo

pip show torch

python -c "import torch; print(torch.version.hip)"

as stated, it was working.

I was able to get it working again after following the debug steps in the readme instructions to reinstall pytorch on linux.

Theres probably 100 gigs of data floating around from the various installs I have made, but I figure its better to leave things alone if they are working.

after reinstalling pytorch as per instructions on comfy readme now everything works
