ImportError:无法从“concurrent.futures.process”导入名称“ProcessPoolExecutor”

Question

我有一个问题，我不知道发生了什么： 我尝试使用以下代码学习多处理教程：

import concurrent.futures
import time

start = time.perf_counter()

def do_something(seconds):
    print(f'sleeping {seconds} second(s)...')
    time.sleep(seconds)
    return 'Done sleeping'

with concurrent.futures.ProcessPoolExecutor() as executor:
    f1 = executor.submit(do_something, 1)
    print(f1.result()) 

我在jupyter笔记本中成功运行了这段代码，但在Pycharm中运行时收到以下错误消息：

/Users/jiangxu/PycharmProjects/Assign_compartment/venv/bin/python /Users/jiangxu/PycharmProjects/Assign_compartment/multiprocessing.py

发生了什么事

我也有同样的问题。这是因为python文件的名称是“multiprocessing”，所以您要做的就是更改它
