Python在使用
bgsubmog = cv2.bgsegm.createBackgroundSubtractorMOG()
去除背景，報錯AttributeError: module ‘cv2‘ has no attribute ‘bgsegm‘
報錯原因：使用的python環境中沒有安裝擴展包contrib
可以通過pip或者conda安裝
pip install opencv-contrib-python
注意：contrib的版本需要和opencv版本一致
在cmd下
pip install opencv-contrib-python
我這里沒有沒有指定opencv-contrib-python版本號，自動匹配了
