请问如何支持多进程

AI-M-BOT commented 1 year ago

目前会报错:

_pickle.PicklingError: Can't pickle <function x at 0x00000123B688D1B0>: attribute lookup x on __main__ failed

不断的启动新进程->新进程启动->本进程报错退出

例子:

#  vim: set ts=4 sw=4 tw=0 et ft=python :
import os
import sys
import multiprocessing as mp
from time import sleep

def foo(q):
    for _ in range(8):
        sleep(1)
        q.put('hello')

if __name__ == '__main__':
    mp.freeze_support()

    msg = 'Hello from %s'%(os.path.abspath(__file__))
    print(msg)
    print()

    for path in sys.path:
        print('>', path)

    q = mp.Queue()
    p = mp.Process(target=foo, args=(q,))
    p.start()
    for i in range(8):
        sleep(1.1)
        print(q.get())
    p.join()

    a = input('just put something')

调用 runtime 里的 python 可执行启动即可

请问还有其他办法么你说的这种方法我没法用才来问的我把一部分变量和实现放在了pystand.exe里

根据https://github.com/skywind3000/PyStand/issues/21, 把函数建立在另一个文件里可行
