I have a problem that I cannot figure out what happened: I was trying to follow a multiprocessing tutorial using the following code:
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())
I ran this piece of code successfully in jupyter notebook but got the following error message when I ran it in Pycharm:
/Users/jiangxu/PycharmProjects/Assign_compartment/venv/bin/python /Users/jiangxu/PycharmProjects/Assign_compartment/multiprocessing.py

so what happened?
