OpenCV = from master branch 7/10/20 Operating System / Platform => Windows 64 Bit Win10 Compiler => Visual Studio 2019

problem: I successfully built opencv in the latest cmake, and then built in VS. My PC recognizes python but does not recognize cv2. I installed both opencv and python in the c:\ drive. I tried adding these paths to my user environment variables, no luck. All my python paths in cmake are also correct. What could be the problem here?

error:

You should try pycharm and anaconda, they have better support for python and easy configuration.It might be better to ask on stackoverflow, where many people use Visual Studio 2019.
