on startupb i get this.

File "D:\ComfyUI\ComfyUI_windows_portable\ComfyUI\custom_nodes\comfyui-NDI__init__.py", line 13, in import NDIlib as ndi ModuleNotFoundError: No module named 'NDIlib'

Cannot import D:\ComfyUI\ComfyUI_windows_portable\ComfyUI\custom_nodes\comfyui-NDI module for custom nodes: No module named 'NDIlib

Thanks for the help in advance

Thanks for the quick reply, still the same error for some reason.

Just wondering would the problem be i am not running my comfy in the same drive could cause issue? since i am running my comfy on my SSD on D:\ and my NDI is installed in C:\users?

Maybe you are using an integrated version of comfyui, the root cause of this problem is that comfyui doesn't have the nid-python package in its python runtime environment. You just need to find a way to install this package in comfyui. If you are using the windows portable version, there should be a python_embedded. E:\ComfyUI_windows_portable\python_embedded\Scripts\pip install ndi-python

Thanks for all the help, I couldn't get it to work on portable. So instead what I did is I installed new ComfyUI then made a venv to install all the python in. After that it seems to work, so for anyone else having a the same problem just have to follow this way to install your comfyui and it will work here is the link:

Thanks for the feedback Ningxiaoxiao.

Hey, In my case, I was missing the CV2 module to ndi node work. I use pinokio, I had to install opencv-python in the virtual env .

Thank you for your comments. I am trying to install python-ndi since weeks without success. I work with comfyui on a secondary 'D' hard disk. I always get the same message no matter where I install it: venv, site-packages, both local and comfyui's own,... Am I missing something? i always get the same error

0.0 seconds (IMPORT FAILED): D:\ConfyUI\ComfyUI_windows_portable\ComfyUI\Custom_nodes\comfyui-NDI

I have tried to install ndi-python in the possible paths like:

D:\ComfyUI_windows_portable\python_embedded\Lib\ D:\ComfyUI_windows_portable\python_embedded\Scripts D:\ComfyUI_windows_portable\python_embedded\site-packages

C:\Users_ComfyUI\windows_portable\pypython\embedded\Lib\site-packages C:\venv\Lib\site-packages C:\venv\Scripts

Any solutions or steps I'm missing?

Thanks

So, there's no way to install NDI and nodes when using the ComfyUI portable version?

Sorry, I forget to install cmake. Now I am getting:
