I do have some troubles with openvino and the Neural Compute Stick 2 on docker:

When I try to run :

python3 object_de
tection_demo.py -d MYRIAD -i /home/openvino/video.mp4 -m /home/openvino/person-vehicle-bike-detection-2004.xml -at ssd --labels /home/openvino/data/dataset_classes/coco_91cl_bkgr.txt -o /home/openvino/output_video.mp4

It doesn't workd and it takes 1 minute to give me this message , whicht is strange due to the ncs2.

[ INFO ] Initializing Inference Engine...
[ INFO ] Loading network...
[ INFO ] Reading network from IR...
[ INFO ] Use BoxesLabelsParser

To close the application, press 'CTRL+C' here or switch to the output window and press ESC key

Any idea ?? Thanks !!

This is an error due to X11 forwarding in docker. GTK backend can't be initialized when X11 forwarding is disabled.
Follow instructions here: Run X application in a Docker container reliably on a server connected via SSH without "--net host"
