Error when running main.py

This is an issue that occurred outside the scope of ComfyUI, so we can't grasp anything from this. You need to provide the full log for us to at least guide you in the right direction.

I found a solution. It's because of an alpha version of mpmath (1.4.0a0) as dependency.

sudo pip3 install mpmath==1.3.0 reverting to 1.3.0 fixes the bug

You might want to look into setting up a virtual environment such that you don't need to run everything with the system python.

Running in the same problem. This happens when you install you'r venv according to the linked apple site.

[easylolicon]

force 1.3.0 version pip install mpmath==1.3.0

[Th3Rom3]

Just as a general word of advice: Using pip via python -m pip instead of just pip can reduce problems since it ensures that pip is invoked within the currently active python environment instead of whatever is found in $PATH.

@stanleyftf1005 Do you know which package has mpmath (1.4.0a0) as a dependency? Is it from a core ComfyUI dependency?

It's been a while since I solved this I cant recall 100%. But I remember it happened when installed a custom node.

Maybe try to look into ComfyMath

mpmath is dependency of following custom nodes:

ComfyUI-DragAnything comfyUI-nsfw-detection ComfyUI-MuseV ComfyUI-aichemy-nodes

especially... ./ComfyUI-DragAnything/requirements.txt:mpmath>=1.3.0

all other custom nodes fix version to 1.3.0
