opencv: Python samples not correct
Some of my students noticed that the python tutorials are incorrect and no longer working. For example the backgroundsubtraction sample here has an error in line
fgbg = cv2.createBackgroundSubtractorMOG()
which should actually be
fgbg = cv2.bgsegm.createBackgroundSubtractorMOG()
I am wondering if this is the case for all functionality and thus, all samples need to be adapted? If so I am able to provide fixes, but I would rather love to have a more experienced python user to confirm this problem.

There is a risk with this! If your
opencv-pythonandopencv-contrib-pythonare out of sync (different versions) than there is about 95% chance it will blow up in your face and your software won’t work. In that case I think it is always better to ensure you built the correct version combination yourself.@swarnak25 , this is not a bug, your cv2 probably does not contain this module
you have to build your cv2 from src with opencv_contrib
