When trying to view image in a window using cv2.imshow, OpenCV Error encountered:
Unspecified error (The function is not implemented. Rebuild the library with Windows, GTK+ 2.x or Carbon support. If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script) in cvShowImage, file /home/yyoo/src/opencv-3.3.0/modules/highgui/src/window.cpp, line 605

After some googling this issue seem to be solved by installing libqt4-dev before compiling. See https://stackoverflow.com/questions/14655969/opencv-error-the-function-is-not-implemented
Please update the binary!
