兄弟们看看是不是这个错：
QObject::moveToThread: Current thread (0xe5205f0) is not the object's thread (0xa14d0f0).
Cannot move to target thread (0xe5205f0)
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "/xxx/python3.8/site-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, eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, webgl.
VScode 80年不出个错，今儿冒出来这个，我也不知道是mmdet配置问题，还是opencv-python的问题，还是VScode的问题hhhh

把QT的flag打开，我们才能看到报错的详细信息
export QT_DEBUG_PLUGINS=1
注意，这个执行后，该环境变量只在当前终端有效，关了这个终端就失效了，当然你也可以写到.bashrc里
然后就整出一个超级长的报错：

与这哥们报的错误差不多
这位大哥这样做的
当然你也可以在环境变量中添加：
export DISPLAY=:0
launch.json 中这样添加
解决是解决了，但是给我整出来一个
Invalid MIT-MAGIC-COOKIE-1 Key(环境变量名字)
暂时不影响
