Recreating venv installs non-functioning version of torch without the proper backend

If you recreate the venv, the default version of torch is installed instead of the one that is specific for your hardware. This causes comfy to fail launching with “cuda not installed” error (same error for AMD backend), thus recreating venv is guaranteed to brick your install.

Is this the same problem I’m having? I can’t even get ComfyUI Desktop to start. I tried deleting everything and reinstalling and I get this in the logs. Bummed out since I was having a good time this weekend learning how to do different things. Now I can’t do anything. Thanks!
