本来是想着好好整理下杂乱无章的代码的，将不同的函数分类整理到不同的py文件中，在主函数中调用的，结果在主函数输入路径中出现了中文字符，就报错了：
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
经过调试，看到的内容是：
warning: Debugger speedups using cython not found. Run '"C:\Users\users\AppData\Local\Programs\Python\Python37\python.exe" "C:\Users\Jia\.p2\pool\plugins\org.python.pydev.core_6.4.3.201807050139\pysrc\setup_cython.py" build_ext --inplace' to build.

(result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xba in position 515: invalid start byte
但是我在定义文件的时候分明已经定义了编码：# -*- coding: utf-8 -*-
上网搜索了很多，都没有搜到解决方法，后来突发奇想，是不是编译器的问题
所以将编译器内的编码格式设定为 utf-8
问题解决！
作为python菜鸟，遇到问题总是从代码层面来找问题，编译器造成的错误也不容忽视。
