python-opencv AttributeError: 'module' object has no attribute 'createBackgroundSubtractorGMG'

Question

I am trying to follow the tutorial given in: https://opencv-python-tutroals.readthedocs.org/en/latest/py_tutorials/py_video/py_bg_subtraction/py_bg_subtraction.html

Answer 1

bgsegm was in contrib module of opencv, but after the update I am not sure.

But still, if you have not built contrib module:

pip install opencv-contrib-python

Make sure no console is running that has imported cv2 while you execute your installing process. Run the cmd as Administration

It worked for me.
