Cannot import D:\comfyui_windows_portable\ComfyUI_windows_portable\ComfyUI\custom_nodes\ComfyUI_FizzNodes module for custom nodes: No module named 'numexpr'

I encountered the above problem~How to solve it?

You are getting this because numexpr failed to install properly from requirements.txt. normally this is because numpy is a requirement for numexpr but the comfyui install should have already installed that so I'm not sure what the case might be for it to still happen. Regardless, here is the fix:

For cloned ComfyUI installs:

• open a cli
• activate your ComfyUI virtual environment
• pip install numexpr

For packaged Comfyui installs:

• Open a cli pathed to your root ComfyUI folder
• .\python_embed\python.exe -s -m pip install numexpr

Let me know if there is any problems with the fix and thank you for letting me know.
