Hi! I'm trying to run Image Deblurring Python Demo from this command: 

python3 deblurring_demo.py -m /media/ssd/public/deblurgan-v2/FP32/deblurgan-v2.xml -i /media/ssd/open_model_zoo/demos/deblurring_demo/python/deblurred_image.png -d MYRIAD 

Could you, please, check that it is everything correct?

And I get the following error:

qt.qpa.xcb: could not connect to display
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "/media/ssd/openvino_env/lib/python3.8/site-packages/cv2/qt/plugins" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: xcb.

Aborted (core dumped)

So, where it is the problem and what can I do to solve it?

Hi Yleal,

Thank you for reaching out to us.

 

Are you using an SSH connection to connect to your device with OpenVINO™ installed?

 

For your information, the "qt.qpa.xcb: could not connect to display" error is due to the SSH connection unable to display the OpenVINO™ demo image result. I got the same error as yours when running Image Deblurring Python Demo remotely using an SSH connection.

Alternatively, a workaround for this is to use X forwarding over SSH. X11 port forwarding/tunneling lets you interact with the GUI of an application running on a remote computer. You can check out these guides below. (These are external links and are not maintained by Intel®)

 

On another note, I manage to enable X11 forwarding over SSH on my device and successfully ran the Image Deblurring Python Demo as shown below:

Thank you very much! It did not work to me because I realized the device I was working to has Ubuntu Server, so I can't see them, but I saved the image and now I can send it or something.
