ubuntu 18.0.4安装relabelimg

进入虚拟环境安装

conda activate py36

或者直接安装

pip install labelImg

使用词语句打开labelimg

rebelImg

打开报错

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.

解决方案：由于缺少相关的依赖库，所以程序运行出错，在Ubuntu下直接通过如下的命令安装即可：

sudo apt-get install libxcb-xinerama0
