带docker的Openvino nsc2:无法在函数“cvInitSystem”中初始化GTK后端

Question

我确实对openvino和docker上的神经计算棒2有一些问题：

当我尝试跑步时：

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
 

它不工作，需要1分钟才能给我这个消息，这是奇怪的，因为ncs2

有什么想法吗？？谢谢

Answer 1

这是由于docker中的X11转发导致的错误。禁用X11转发时，无法初始化GTK后端。
请按照此处的说明操作：Run X application in a Docker container reliably on a server connected via SSH without " net host"
