所以我正在尝试多处理功能F.可以通过按钮按下tkinter来访问。
def f(x):
global doom,results,info
doom = doom + 1
if check(x) == True:
results.add(x)
info.append(get_column_number(x))
j.step(1)
texx = "1/"+doom
s.configure(text=texx)
root.update()
在如下函数中调用函数：
def dojob():
index = ['URLS'...]
pool = Pool(processes=4)
s.configure(text="Shifting Workload to cores..")
root.update()
pool.map(f, index)
按钮位于根窗口内。
我收到以下错误：
Exception in thread Thread-2:
Traceback (most recent call last):
File "C:\Python27\lib\threading.py", line 808, in __bootstrap_inner

我甚至不知道泡菜是做什么的？帮助

答案 0 :(得分：2)
你正在泄漏一个tkinter对象。很可能是因为您尝试使用最后一行f()
根据代码进行更新
您的f()中的函数f与变量__main__之间存在名称冲突，该变量会被分配到主窗口并导致tkapp pickle错误。将函数重命名为def myfunc()或其他内容。还需要在pool.close（）
