Tortschi commented 4 years ago

Hello,

i get a Problem when i run the Code on an Ubuntu Server 18.04. When i use: python eval.py –video="https://www.youtube.com/watch?v=hfeNyZV6Dsk"

i get this Error: : cannot connect to X server

Whats the Problem for it?

looks like something wants to have GUI. I don't remember any components in devicehive-video-analysis that uses actual UI... maybe opencv wants it(it has some UI components, but they are not used in this project).

Alternativly, you can try to run it with virtual UI using Xvfb. xvfb-run python eval.py –video="https://www.youtube.com/watch?v=hfeNyZV6Dsk"
