    cv2.imshow('result', img)
cv2.error: OpenCV(4.8.0) /io/opencv/modules/highgui/src/window.cpp:1272: 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'

貌似因为之前 pip3 install opencv-python-headless 安装后导致版本不一致了。

解决方案

pip3 uninstall opencv-python
pip3 install opencv-python-contrib
pip3 install opencv-python
