Python3|Python3 AttributeError: module 'cv2' has no attribute 'createBackgroundSubtractorMOG' Python3AttributeError:module'cv2'has

问题：在用python3使用cv2.createBackgroundSubtractorMOG()的时候，可能会产生错误：AttributeError: module 'cv2' has no attribute 'createBackgroundSubtractorMOG'

import numpy as np import cv2 cap = cv2.VideoCapture(0) fgbg = cv2.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()

报错信息：

--------------------------------------------------------------------------- AttributeErrorTraceback (most recent call last) in () 2 import cv2 3 cap = cv2.VideoCapture(0) ----> 4 fgbg = cv2.createBackgroundSubtractorMOG() 5 while(1): 6ret, frame = cap.read()AttributeError: module 'cv2' has no attribute 'createBackgroundSubtractorMOG'

解决：将fgbg = cv2.createBackgroundSubtractorMOG()替换为：
fgbg = cv2.createBackgroundSubtractorMOG2()
分析：
在python3中，缺少cv2.createBackgroundSubtractorMOG()方法改为了cv2.createBackgroundSubtractorMOG2()。
变更样例：

fgbg = cv2.createBackgroundSubtractorMOG2()

说明：问题产生的环境
Python版本：3.6.5
OpenCV版本：3.4.2
