==========================================

使用ubuntu系统下python的seaborn模块画图，报错：

qt.qpa.plugin: Could not load the Qt platform plugin “xcb“ in ““ even though it was found

在网上搜索资料，发现是Qt加载插件出现问题，通过在终端中通过设置QT_DEBUG_PLUGINS=1，可以查看Qt的插件加载信息。

export QT_DEBUG_PLUGINS=1

再次运行之前的报错代码，会显示出调试信息，根据其中的报错信息对缺失的组件进行安装。

本人安装的缺失组件：

sudo apt install libxcb-icccm4-dev

sudo apt install libxcb-render-util0-dev

sudo apt install libxcb-render0-dev

sudo apt install libxcb-keysyms1-dev

sudo apt install libxcb-image0-dev

sudo apt install libxcursor-dev

sudo apt install libgl1-mesa-glx

sudo apt install mesa-utils

sudo apt install mesa-common-dev

sudo apt install mesa-opencl-icd
