OpenCV2 Python createBackgroundSubtractor module not found

Question

I am trying to use cv2.createBackgroundSubtractorMOG2 () method in Python. I have tried both on my Mac and on my Raspberry Pi, and get the same error when running the follow

Answer 1

I'm using

>>> import cv2
>>> cv2.__version__
>>> 3.2.0

and python 2.7.12. While I tried to use cv2.createBackgroundSubtractorMOG() I received the same error message (also tried without "create..."). But I was surprised when I discovered cv2.createBackgroundSubtractorKNN() with the same functionality instead ... and the test code works :) 2 days I was confused and couldn't find where the problem is.
