报错日志如下：

环境: pipenv pyenv

为了兼容 pyenv 环境下的代码兼容性问题：

我添加了如下代码

import matplotlib

matplotlib.use('TkAgg')

[program-spiritual]

解决方案 ：(替换渲染引擎)

1. 安装PyQt5

pip3 install PyQt5

2. 设置 backend： backend: Qt4Agg

echo "backend: Qt4Agg" >> ~/.matplotlib/matplotlibrc

或者

vim    ~/.matplotlib/matplotlibrc

添加：

backend: Qt4Agg
