Torch not compiled with CUDA enabled

[TwoPintOhh]

The pip insrall -f requirements_win.txt removes packages that are needed for ComfyUI to run and installs incompatable versions, breaking Comfy

to replicate this, install comfy, clone the git rep for Lora-Training-in-Comfy into the Custom nodes folder, pip install the requirements_win.txt

I have had the same issue using Stability matrix and the official ComfyUi installations, the following is via Stability Matrix after making sure Comfy was up to date. Comfy will not run.

I'm getting the same errors on twon new Comfy installs on windows+cuda.
Seems this toolset breaks Comfy?

[acgc99]

Same issue here, using or not Stability Matrix

[WilyGuys]

Any fix on this? Having the same problem... ComfyUI is broken

I think these custom nodes are doing something weird. I just reinstalled comfy with stability matrix and not install this custom nodes.
