python - 无法从 'Process' 导入名称 'multiprocessing'

Question

我写了一个 python 代码来使用多处理计算数字的平方。它显示下面的错误。如何修复它。

import os
from multiprocessing import Process, current_process


def sqaure(number):
    result=number*number
    process_id=os.getpid()
    print(f"Process ID : {process_id}")
    print(f"the number {number} sqaures to {result}")

if __name__=='__main__':
    numbers=[1,2,3,4]
    processes=[]
    for number in numbers:
        process=Process(target=sqaure, args=(number,))
        processes.append(process)

        process.start()

错误:

Traceback (most recent call last):
  File "C:/Users/Rohan/PycharmProjects/untitled1/hyu.py", line 2, in <module>
    from multiprocessing import Process, current_process
ImportError: cannot import name 'Process' from 'multiprocessing' (C:\Users\Rohan\PycharmProjects\untitled1\multiprocessing.py)

Answer 1

您的 python 文件名为“multiprocessing.py”，这将与 multprocessing 模块发生冲突。只需重命名您的脚本名称即可。
