1.按github上labelImg项目下README安装`labelImg`时报错如下：

(labelImg) xx@xx-Lenovo-Legion-Y8000:~/SW$ labelImg qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" 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: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, webgl, xcb.

已放弃 (核心已转储)

这样肯定不行，报错没有有用信息，查了下

linux下设置环境变量 QT_DEBUG_PLUGINS=1,

(labelImg) xx@xx-Lenovo-Legion-Y8000:~/SW$ export QT_DEBUG_PLUGINS=1
‵‵‵

然后再启动labelImg会有详细信息输出：
