I had a similar problem:
我有一个类似的问题：

My Python version is 3.8.0 under Windows 10. The problem was the opencv version installation.
我的python版本是windows 10下的3.8.0，问题是opencv版本安装的。
So I fixed this way (cmd prompt with administrator privileges):
所以我以这种方式修复（具有管理员权限的 cmd 提示）：
- Uninstalled opencv-python:
pip uninstall opencv-python - Installed onlyopencv-contrib-python:
pip install opencv-contrib-python
- 卸载opencv-python：
pip uninstall opencv-python - 只安装了opencv-contrib-python：
pip install opencv-contrib-python
Anyway you can read the following guide:
无论如何，您可以阅读以下指南：
回答by snehit vaddi
python -m pip install --user opencv-contrib-python
After doing this just Restart your systemand then if you are on Opencv >= 4.* use :recognizer = cv2.face.LBPHFaceRecognizer_create()
执行此操作后，只需重新启动系统，然后如果您使用的是 Opencv >= 4.* ，请使用：recognizer = cv2.face.LBPHFaceRecognizer_create()
This should solve 90% of the problem.
这应该可以解决 90% 的问题。
