QXcbConnection: Could not connect to display Aborted error

edit

Hello. I am currently working with OpenCV 3.0.0 beta version. I ran a facedetect algorithm on my local system and it worked perfectly fine.

However, When i ssh into an Isaac cluster wherein i have mounted my OS on, i get the following error:

QXcbConnection: Could not connect to display Aborted

Kindly suggest what should be done? Any suggestion or discussion in this regard is highly appreciated.
