AttributeError: module 'cv2.cv2' has no attribute 'bgsegm

Question

import numpy as np
import cv2
cap = cv2.VideoCapture('vtest.avi')
fgbg = cv2.bgsegm.createBackgroundSubtractorMOG()
while(1):
    ret, frame = cap.read()
    fgmask = fgbg.apply(frame)
    cv2.imshow('frame',fgmask)
    k = cv2.waitKey(30) & 0xff
    if k == 27:
        break
cap.release()
cv2.destroyAllWindows()

I am getting the following error: AttributeError: module 'cv2.cv2' has no attribute 'bgsegm'.

I am using Python 3.6 with OpenCV 3.6 on windows machine. I tried using the pip install opencv-contrib-python command but still the problem remains same on my windows machine. This command helped be on Ubuntu system, but not on windows. I searched similar problems on stack but couldn't solve this issue. Can someone help me out on this? Thanks!

You need to install the contrib dependencies to get this working as it isn't part of the standard build.

pip install opencv-contrib-python
