I ran the following command to install an older version of opencv-contrib-python (4.0.0.21). Then an error occurred and this package could not be installed. How can I resolve this error?
pip install opencv-contrib-python==4.0.0.21
Collecting opencv-contrib-python==4.0.0.21

The version you specified opencv-contrib-python (4.0.0.21)
does not have a relevant python3.8 version.
You need to use opencv corresponding to python3.8, or lower your python version to match the opencv version.
