我使用 opencv 和迁移学习模型（resnetSSD）构建了一个人脸检测应用程序。应用程序的输出：视频将打开，模型将能够识别面孔。
应用程序在我的本地系统中完美运行..也能够构建docker，但是当运行docker容器时出现以下错误：
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "/usr/local/lib/python3.6/dist-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.
请建议我如何解决这个问题？
