you are certainly not alone. This issue generally occurs with incorrect OpenCV configurations or compatibility issues. Let's delve into the reasons behind this error and how you can resolve it effectively.

Understanding the Error

Incorrect Package Installed: There are multiple OpenCV packages, and the one with extra contributions is named opencv-contrib-python. Ensure you have this package installed rather than the standard opencv-python.

Incomplete Installation: The installation might be incomplete or corrupted, causing certain modules to be unavailable.

Steps to Resolve the Error

Reinstalling the Correct Package
Firstly, verify if the opencv-contrib-python package is correctly installed. Uninstall any existing OpenCV packages and then reinstall the desired package. Use the following commands to do this:
