What must I do to get it working ?

Sorry, I only checked the default configuration and did not check python. You can see Configuration. 

OpenCV modules:
    Unavailable:                 java js python2 python3
......
Python (for build):            NO

If you want to use opencv in python, please check it and compile it yourself.
