That's a bug with pytorch 2.4. Use the package linked on here: https://github.com/comfyanonymous/ComfyUI/releases/tag/v0.0.4 it has pytorch 2.3.1 or downgrade to pytorch 2.3.1

I use this Comfyui-cpu to run on cpu only web servers. Comfyui-cpu is a trimmed down fork here https://github.com/ArdeniusAI/ComfyUI-cpu
