python – 使用py2exe打包py文件时“超出最大递归深度”

几个月前py2exe在同一个py文件上工作得很好.但是当我今天再次尝试它时,通过报告“RuntimeError：超出最大递归深度”失败了.结果我得到一个空的“dist”文件夹.
Py文件正常工作,它无法打包.我猜py文件中导入的模块有问题.但我无法弄明白.有人知道解决方案吗？

我的py文件的开头部分是：

import xlrd
import wx
import wx.lib.filebrowsebutton as filebrowse
from scipy.optimize import fsolve
import math
import threading
from sympy import Symbol
from sympy import solve

cmd窗口的最后几行是：

File "D:Python27libsite-packagespy2exemf.py",line 332,in _safe_import_hook
self.import_hook(name,caller,level=level)
File "D:Python27libsite-packagespy2exemf.py",line 719,in import_hook
return Base.import_hook(self,name,fromlist,level)
File "D:Python27libsite-packagespy2exemf.py",line 137,in import_hook
m = self.load_tail(q,tail)
File "D:Python27libsite-packagespy2exemf.py",line 214,in load_tail
m = self.import_module(head,mname,m)

self.msg(3,"import_hook",level)
