I tried deleting the files in the cache, but it didn't work. Instead, it created the files and told me they already existed. I also tried updating triton, but it didn't work.

I'm having the same issue. I deleted everything in the cache folder and restarted ComfyUI, but still getting the error. I was able to run the Compile Model+ node once ok, but now it's borked.

i'm having this issue too.

It might be torch's issue.
pytorch/pytorch#138211 and woct0rdho/triton-windows#10 might be helpful.

This worked for me. Specifically this post:
woct0rdho/triton-windows#10 (comment)

I opened this file \ComfyUI_windows_portable\python_embeded\Lib\site-packages\torch\_inductor\codecache.py

And replaced tmp_path.rename with tmp_path.replace

Thanks!
