Check the python in the ComfyUI_windows_portable\python_embeded. Windows portable is using that portable python to run comfy.

Go to python_embeded then do .\python.exe -m pip list

[bananasss00]

It appears that numpy version 2+ is not compatible. Try installing numpy==1.26.4.

There's something you need to check before addressing the numpy issue. How are you running ComfyUI? If you're running it using run_nvidia_gpu.bat, you shouldn't use pip directly. You have to execute pip via python_embeded\python.exe -m pip

And separately from that issue, your ComfyUI path is located too deep in the directory structure. Unless you've modified the Windows registry to change the settings, you'll likely encounter issues with accessing long paths.

Exactly ! That should be in the readme.

i had been doing python main.py i just tried run_nvidia_gpu and new error

encode_image

That is a totally different issue. You need to create new issue with your workflow.

After Cracking my skull for two days straight, this fixed the problem in less than a minute! It definitely should be in the readme as JorgeR81 suggested.
