Not able to display image/video in ubuntu using OpenCV and Python

asked 2016-08-10 08:04:47 -0600

cv2.imshow() is not working in Ubuntu 14.04 with OpenCV 3.0.0 and Python 2.7, facing an error saying "(dsp:3071): Gtk-WARNING **: cannot open display:"

I have tried to update libgtk2.0-dev library, but still not able to view/display the image in Ubuntu

Thanks, Sri

Are you working remotely to this machine? If so it means your X11 pipes are configured incorrectly, which has not really something to do with OpenCV.

Hello,

Solve the problem by adding a variable named "DISPLAY" with value ":0.0" in the run configurations section of eclipse for your project as shown in the screenshot.
