Tkinter回调和追溯记录和Jupyter Notebook问题

如何解决Tkinter回调和追溯记录和Jupyter Notebook问题

所以下面是一个使用Tkinter的GUI界面，在这里我试图在按下按钮后调用基本功能，问题是当我在Jupyter Notebook中执行此功能时，程序可以正常工作。 但是当我尝试以脚本（.py）文件形式运行时，它在命令外壳中给出了错误

查询1-以下如何解决此问题，因为我无法找出错误，我想我没有在此处传递参数？

查询2-为什么在Jupyter Notebook中没有错误出现而在Python Shell中没有发生错误？

我正在使用Python 2.7

注意：-我面对NumPy在3.7和3.8中没有导入错误，因此我不得不切换到较低版本的python来解决此问题（无法卸载并安装NumPy，因为它是办公室笔记本电脑，没有管理员权限）

Python Shell错误：

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!

Importing the numpy c-extensions Failed.
- Try uninstalling and reinstalling numpy.
- If you have already done that,then:
  1. Check that you expected to use python3.7 from "C:\ProgramData\Anaconda3\python.exe",and that you have no directories in your PATH or PYTHONPATH that can
     interfere with the Python and numpy version "1.18.1" you're trying to use.
  2. If (1) looks fine,you can open a new issue at
     https://github.com/numpy/numpy/issues.  Please include details on:
     - how you installed Python
     - how you installed numpy
     - your operating system
     - whether or not you have multiple versions of Python installed
     - if you built from source,your compiler versions and ideally a build log

- If you're working with a numpy git repository,try `git clean -xdf`
  (removes all files not under version control) and rebuild numpy.

Note: this error has many possible causes,so please don't comment on
an existing issue about this - open a new one instead.

Original error was: DLL load Failed: The specified module Could not be found.

解决方法

好的，所以当您指出错误所在的行后，我对其进行了追溯，并发现我正在调用的函数具有一些引起问题的因变量 下面是我最终的结果，谢谢
