ComfyUI Import Failed for custom nodes - ModuleNotFoundError: No module named 'numba'

[Seek4samurai]

I've also created a separate enviroment for the custom node to installl deps. Followed this to install the custom node: https://github.com/WASasquatch/was-node-suite-comfyui?tab=readme-ov-file#recommended-installation

This is something I'm facing since quite a while, I've done some research but nothing seems to work. I've updated deps, created envs for custom nodes & tried a new clean installation as well. I've manually tried installing the numba library as well but still the same issue.

Thanks in advance.

I have the same problem these last few days.

Install or upgrade numba pip install -U numba

UPDATE: The problem was resolved using the install_alt.bat in the directory

@WASasquatch Hi, same problem here, I already try to apply your suggestion, but says that numba is already installed ou updated:

D:\ComfyUI_windows_portable>pip install -U numba Requirement already satisfied: numba in c:\users\julianoa\appdata\local\programs\python\python312\lib\site-packages (0.60.0) Requirement already satisfied: llvmlite<0.44,>=0.43.0dev0 in c:\users\julianoa\appdata\local\programs\python\python312\lib\site-packages (from numba) (0.43.0) Requirement already satisfied: numpy<2.1,>=1.22 in c:\users\julianoa\appdata\local\programs\python\python312\lib\site-packages (from numba) (2.0.2) Any other suggestion?

It looks like that is a system level installation. You need to install numba to the venv that ComfyUI runs on.

This still an issue with the latest install.

pip shows numba is installed, and as far as I can tell it does not run in an env.

the pip install has to happen in the compfyui local python install namely: \ComfyUI_windows_portable>.\python_embeded\python.exe -m pip install numba

This fixes the issue --- Why oh why are are not the custom nodes installing what that need and what is not included with the .\python_embeded\ directory.
