AttributeError: module 'cv2' has no attribute 'RETR_EXTERANL'

AttributeError: module 'cv2' has no attribute 'RETR_EXTERNAL' 是因为在使用cv2模块时，调用了一个不存在的属性。根据引用中提到的，在python3中，cv2.createBackgroundSubtractorMOG()方法已经被改为cv2.createBackgroundSubtractorMOG2()。这意味着在Python3中，使用cv2模块时应该使用cv2.createBackgroundSubtractorMOG2()方法而不是cv2.createBackgroundSubtractorMOG()方法。所以，如果你遇到了AttributeError: module 'cv2' has no attribute 'RETR_EXTERANL'的错误，你可以考虑将cv2.createBackgroundSubtractorMOG()替换为cv2.createBackgroundSubtractorMOG2()来解决问题。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
