Hey guys,
I'm trying to do some video processing on TX2 and when I try to display the output, I get the following:
File "img_test.py", line 142, in <module>
cv2.imshow('frame',frame) cv2.error: OpenCV(4.0.1-dev) /home/nvidia/opencv/modules/highgui/src/window.cpp:627: 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'
I tried to see which Opencv version TX2 was using and it's using 4.0.1-dev. Upon searching for libopencv, I get the following:

Can someone help me with getting rid of the error? Also, will it be possible if I can get rid of all the extra versions of Opencv?
