我收到此错误：

Traceback (most recent call last):
  File "main.py", line 95, in <module>
    if mPLocX > mPLocY:
TypeError: '>' not supported between instances of 'vectorize' and 'vectorize'

从这个程序：

循环代码第一次运行时没有错误，第二次运行时，mx和my变成了形状，错误出现在第62 - 71行。
我试着去掉vectorize，但是不起作用，我试着在所有独立变量上使用astype，但是不起作用，它只适用于if/else，因为在第一个循环中，它们不是形状。
