OpenCV Installation Error: 'opencv_contrib_python-3.4.11.41-cp37-cp37m-win_amd64.whl' Not Supported

This error usually happens when you try to install an OpenCV version that doesn't match your system.

In this case, you're attempting to install the 'opencv_contrib_python-3.4.11.41-cp37-cp37m-win_amd64.whl' file. This file is meant for OpenCV version 3.4.11.41 on a 64-bit Windows system.

However, your system seems incompatible with this specific version.

To fix this, try downloading a different OpenCV version that works with your system. You could also check for any required dependencies or prerequisites that need to be installed before you can install OpenCV.
