我正在尝试使用多处理流程，但出现此错误`RuntimeError： 尝试在启动新进程之前启动新进程。 当前进程已完成其引导阶段。
This probably means that you are not using fork to start your
child processes and you have forgotten to use the proper idiom
in the main module:
if __name__ == '__main__':
freeze_support()
...
The "freeze_support()" line can be omitted if the program
is not going to be frozen to produce an executable.` but the issue is I have if __name__ == '__main__': already in my run.py file.
当我使用Google这个错误时，有人告诉我在已有if语句时添加它。
run.py
if __name__ == "__main__":
from inventory import update_inventory2
update_inventory2.py
print("update_inventory")
while True:
print("starting")
p = Process(target=add_to_queue, args=(db, ))# db is just the db being used and has no baring on my issue.
p.start()
p.join()
starting
update_inventory

Should not be trying to run twice, not sure if it's related.
