OpenCV Error: 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 /io/opencv/modules/highgui/src/window.cpp, line 583

I use python3.5.2, The libgtk2.0-dev and pkg-config have been already installed. Thanks!

Hi, this seems like an issue specific to your system, but could you send your command line so that I can try to recreate the issue?

My command line is "python play_radar.py ~/Downloads/2019-01-10-14-36-48-radar-oxford-10k-tiny/radar"
