我收到一条错误消息，说应用程序已被破坏。我已经收到了关于早期不完整版本的代码的回复，该版本没有解决问题，所以我有点担心。我是国际米兰的新手，所以我不太擅长这个。

如果这不是你想要的答案，请纠正我。
运行此代码时收到的错误为_tkinter.TclError: can't invoke "button" command: application has been destroyed。此错误仅在关闭应用程序时出现。按钮根本没有出现。根据这个堆栈溢出问题，出现错误是因为您在创建按钮之前调用了root.mainloop()。
在我解决了这个问题之后，我不得不重新安排函数checkDirections()。
然后得到错误_tkinter.TclError: cannot use geometry manager grid inside . which already has slaves managed by pack。根据这个堆栈溢出问题：
错误会告诉你到底出了什么问题：你不能将pack和grid都与共享公共父的小部件一起使用
在这一点上，我不能再往下说了，因为我从未使用过pack、numpy和matplotlib，我不知道你希望你的窗口布局如何。
这就是我得到_tkinter.TclError: cannot use geometry manager grid inside . which already has slaves managed by pack错误的地方，我希望你能从这里继续：
