我有一个问题，我无法弄清楚发生了什么：我试图使用以下代码遵循多处理教程：

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 Notebook 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：

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()) 

所以发生了什么事？
