Unable to load nvfuser_codegen.dll

Your question

Not sure why but I updated comfy and suddenly started getting errors loading torch. The file IS there in that location, so I'm not sure what the problem might be. Originally it had another error in the torch init, but after doing some troubleshooting it's now this error. I should note, this particular log is from a swarmUI comfy install, but I also get the same error on my separate comfyui install. I have already reinstalled the entire UI and it's still giving this error.

This seems to be a symptom of your torch being corrupted. It appears you're using venv, so try reconstructing your venv.

If you're still experiencing the same symptoms, try downloading and using the portable version for comparison. At the very least, the portable version will prevent the possibility of mistakes during the environment setup process.
