Originally, I was thinking of organizing the cluttered code, sorting different functions into different py files and calling them in the main function, but as a result, Chinese characters appeared in the input path of the main function, and an error was reported.

SyntaxError: Non-UTF-8 code starting with ‘\xba’ in file D:\Python Projects\RidgeMorphology\src\ridgemorph.py on line 19, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details

After debugging, the content seen is:

But I clearly defined the encoding when I defined the file: # -*- coding: utf-8 -*-

I did a lot of searching on the Internet, but I couldn’t find a solution, and then I had a sudden thought that it was a compiler problem

So I set the encoding format in the compiler to utf-8

Problem solving!

As a python rookie, I always look for problems at the code level when I encounter them, and errors caused by the compiler should not be ignored.
