Error: cannot connect to X server #18

Closed man0007 closed 4 years ago

DevashishPrasad commented 4 years ago

If you are using Google Colaboratory (Colab), Then you need to add

from google.colab.patches import cv2_imshow and replace all the cv2.imshow("name",image) with cv2_imshow(image)

HI,

Thanks for the quick response, I'm running it in the Azure (cloud) linux machine, which is very much equivalent to my local linux machine.

Thanks, Anand.

Install an X Server and enable RDP in your Azure Linux VM. Follow this guide -

https://docs.microsoft.com/en-us/azure/virtual-machines/linux/use-remote-desktop.

After you enable RDP, you can use the Windows Remote Desktop Connection to connect to your Azure Linux VM. This will provide you with a full-fledged Desktop screen with all graphical screens. OpenCV cannot show images in a UI if the X server is not configured with proper permissions. Open a Terminal from the Desktop, and issue the following commands from your home folder:

chmod 777 .Xauthority chmod 777 .ICEauthority cp .Xauthority .ICEauthority /root

Test if the X server is responding by issuing the command - "xclock". If a UI wondow comes up with the clock, then your X server is working. OpenCV can then show results in a UI window.

xml output:
