import multiprocessing
import time

def worker():
    n=5 #number of process
    while n>0:
        print("the time is {0}".format(time.ctime()))
        time.sleep(2)
        n-=1

if __name__=="__main__":
    p=multiprocessing.Process(target=worker)
    p.start()
    print("end")

我真的不知道如何解决这个问题一旦我使用多处理，将发生属性错误错误消息总是显示AttributeError，无论我做什么

python多处理AttributeError
