错误代码如下：
cv2.error: OpenCV(4.12.0) D:aopencv-pythonopencv-pythonopencvmoduleshighguisrcwindow.cpp:1301: error: (-2:Unspecified error) The function is not implemented. Rebuild the library with Windows, GTK+ 2.x or Cocoa support. If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script in function 'cvShowImage'
原因：
OpenCV 4.12.0 默认关闭了cv2的一些函数，两种办法 一种是修改配置。另外一种换成4.11版本

以下是卸载旧的扩展安装新的版本

pip uninstall opencv-python
pip uninstall opencv-contrib-python

安装opencv4.11

pip install -i https://mirrors.aliyun.com/pypi/simple/ opencv-python==4.11.0.86
pip install -i https://mirrors.aliyun.com/pypi/simple/ opencv-contrib-python==4.11.0.86
