问题：Mixing Qt major versions may not work as expected.

UserWarning: Matplotlib is using PySide6 which wraps 6.6.3 however an instantiated QApplication from PyQt5 which wraps 5.15.2 exists.  Mixing Qt major versions may not work as expected.

解决：安装上PyPySide6

pip install  -i https://mirrors.aliyun.com/pypi/simple  PySide6
