这是我的代码……我觉得是完全正确的……但是错误提示是
AttributeError: module 'cv2.face' has no attribute 'LBPHFaceRecognizer_create'
我已经在谷歌、YouTube、StackOverflow等地方尝试了很多方法，但都没有解决这个错误。
我还换了Python版本
用命令
pip install opencv-python
还有
pip install opencv-contrib-python
我已经做了很多次，但还是没有找到解决办法。

这个错误的意思是你在用错误的方法来创建一个LBPH人脸识别器，使用的是OpenCV这个库。
如果你使用的是OpenCV 4.x或更新的版本，你应该用这个方法：cv2.face.LBPHFaceRecognizer_create()。如果你用的是OpenCV 3.x或更早的版本，那就要用这个方法：cv2.createLBPHFaceRecognizer()。
你可以通过运行cv2.__version__来检查你当前的OpenCV版本，然后根据版本使用正确的方法。
