More significantly you used numpy to do it and that seems
to be where the issues lie, not in Tkinter.

Numpy is part of SciPy which has a dedicated support forum

I'm not sure how you are using Tkinter here because you didn't
send any code but looking at the traceback your code is
getting called by Tkinter somehow.

That aside, the real issue seems to be here:

I have no idea how the numpy stuff works but it looks like a data error,
maybe you are passing the wrong type?

But we'd need to see where 'a' and 'b' come from to be sure.

BTW its probably a bad idea to put your code (ed.py) inside the Python
folder structure, better to have a separate work space for your own
files. Especially if you install another version of Python and
want your code to work with it too.
