这是我得到的错误:
Traceback (most recent call last):

我在windows中使用了python 3.4的py2exe。我可以从python运行相同的代码,并在转换.exe文件后,它不会运行并给出上述错误消息。从.py转换为.exe时没有错误。该代码使用Tkinter制作GUI,并且还使用纸浆进行线性优化。有谁知道为什么会这样? 部分代码:
from tkinter import *
from tkinter.ttk import *
from pulp import *
class Gui(Frame):
def __init__(self, parent):
Frame.__init__(self, parent)
self.parent = parent
self.initUI()
def optimizations(self):
numberEzroofmtg, lngths, wdths, hghts = self.lengthsEzmtg()
prob = pulp.LpProblem('the simple problem', LpMinimize)
self.indices = ['206_rail','164_rail','124_rail','84_rail']
self.x = pulp.LpVariable.dict("x_%s", self.indices,lowBound =0, cat = LpInteger)
# length data
self.lengths = dict(zip(self.indices, [206, 164, 124, 84]))
prob += sum([self.x[i]*self.lengths[i] for i in self.indices]) >= lngths
prob += self.x['124_rail'] <= 1
prob.solve()
return int(self.x['164_rail'].value())*2, int(self.x['124_rail'].value())*2
self.quit()
def testsubmit(self):
Rails_164, Rails_124 = self.optimizations()
self.entries['Number of Helio Std. Rail (L=164)'].delete(0,END)
self.entries['Number of Helio Std. Rail (L=164)'].insert(0, Rails_164 )
答案 0 :(得分:1)
看起来纸浆模块无法找到可用的求解器。从我可以告诉它使用外部DLL和命令来解决,py2exe无法知道这一点,因此不包括它们。您需要明确告诉py2exe您正在使用这些文件,可能是使用dist-file
脚本中的setup.py
