Labelme安装以及qt.qpa.plugin: Could not load the Qt platform plugin “xcb“ in ““ even though it was f问题解决

我在ubuntu18.04下安装的，直接使用下面命令行直接安装

pip3 install labelme

安装结果如下：

安装完成后直接在终端输入labelme运行：

labelme

报错：

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)

解决方案如下：

sudo apt-get install libxcb-xinerama0

最后再次运行labelme，运行成功
