"Can't initialize GTK backend in function 'cvInitSystem'" #1107

Hi all,

I was following the instructions from here to flash the VCK190 image to an SD card, and then the instructions from here to run the resnet50 example. However, I error out with the following message:

I am using minicom to communicate with my VCK190 platform. Based on this issue from the OpenCV repository, it seems like it's an X11 issue. However, since I'm using minicom, I'm not really sure how to proceed here. Any help is appreciated!

I don't think minicom can support X11 show. Please use other port such as DP or HDMI. Or for the aim to run the code, you can comment out the opencv part.

I faced the same issue when working with KV260. You need to use: export DISPLAY=:0 if you're working directly with the display output of the platform, otherwise use export DISPLAY=[your_ip_address]:0.0 if you’re working remotely.

Regards!
