When you have difficulty installing openCV on Nuke

A few days ago, I had an error after upgrading to Nuke 15, and here’s how I solved it. It turned out that Python’s site-packages were specified in the wrong path, so it didn’t recognize cv2 and numpy. Please check these if you get an error message

01. error message <Nuke cmd window>

or have problems installing cv2 on Nuke.

02. import cv2 error message <Nuke Script Editor

1. Check your version

  1. Check your Python version
python --version

2. install the numpy version

  • In a cmd window, type pip install numpy==1.22.4 to install version 1.22.4.

3. Upgrade Nvidia Cuda (Not directly related)

  • In my case, it asked me to upgrade NVIDIA when nuking, so I entered NVIDIA Geoforce and installed the driver and the error message disappeared.

2. Check the file path

4. C:\Program Files\Nuke15.0v2\pythonextensions\site-packages

folder must have the following folders to work normally.

(I had these folders in my personal path C:\Users\[MypersonalName]\Desktop\pythonProject3\Lib\site-packages)

Here is the zip file for the site-packages : Click to download (via Google drive)
