解决mayavi调用时出现错误

错误内容：
qt.qpa.plugin: Could not find the Qt platform plugin “windows” in “”
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
解决：环境变量那些方法无效，找到以下解决方法：

import os
import PySide2

dirname = os.path.dirname(PySide2.__file__)
plugin_path = os.path.join(dirname, 'plugins', 'platforms')
os.environ['QT_QPA_PLATFORM_PLUGIN_PATH'] = plugin_path

添加此代码后就可以运行：

from mayavi import mlab
