pyarmor多次显示tkinter窗口。

Question

在tool.py代码脚本下面，同时使用cmd运行该代码

tool.py命令，它100%成功运行。

当我试图在cmd中使用pyarmor命令打包代码时

pyarmor -e“-onefile”tool.py

然后我运行exe文件，当我按submit按钮时，它会显示win00窗口，首先它开始运行代码。

但是在运行它的过程中，它再次显示tkinter win00窗口，这将停止第一段代码的运行。

Func00和Func01包括多处理过程，每个Func包含5个进程。

tool.py

import tkinter as tk
from deployedFunc00 import *
from deployedFunc01 import *

def button_fn():
    if clicked.get() == 'func00':
        if __name__ == '__main__':
            Func00()
    else:
        if __name__ == '__main__':
            Func01()
            
def show():
    label_.config(text=clicked.get())
    
if __name__ == '__main__':
    win00 = tk.Tk()
    win00.geometry("300x300")
    win00.eval('tk::PlaceWindow . center')

    frame00 = tk.Frame(win00)
    frame00.pack_propagate(0)
    frame00.pack(fill=tk.BOTH, expand=1)

    options = ['func00','func01']
    clicked = tk.StringVar()
    clicked.set('func00')

    drop = tk.OptionMenu(frame00, clicked, *options)
    drop.pack()
    
    label_ = tk.Label(frame00, text=" ")
    label_.pack()
    
    button0 = tk.Button(frame00,text="choose",command=show).pack()

    button1 = tk.Button(frame00,text='submit',command= button_fn)
    button1.pack(side=tk.BOTTOM,pady=(0,10))

    win00.mainloop()

deployedFunc00.py

import multiprocessing
from func05 import *


def Func00():
    LENGTH = 5


    jobs = []         
    for n in range(LENGTH):
        globals()['p_%s' %n] = multiprocessing.Process(target = Func05)
        
    for n in range(LENGTH):
        jobs.append(globals()['p_%s' %n])
        
    for n in range(LENGTH):
        globals()['p_%s' %n].start()
        
    for proc in jobs:
        proc.join()

deployedFunc01.py

import multiprocessing

from func06 import *

def Func01():
    LENGTH = 5


    jobs = []         
    for n in range(LENGTH):
        globals()['p_%s' %n] = multiprocessing.Process(target = Func06)
        
    for n in range(LENGTH):
        jobs.append(globals()['p_%s' %n])
        
    for n in range(LENGTH):
        globals()['p_%s' %n].start()
        
    for proc in jobs:
        proc.join()

Answer 1

最后我找到了一个解决方案:只需

multiprocessing.freeze_support()

之后

if __name__ == '__main__':
