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.
