python NameError：全局名称'multiprocessing'未定义

Question

I am trying to convert my threaded code to multiprocessing code. but it is giving me error

    Name Error: global name 'multiprocessing' is not defined

Multiprocessing is installed and I imported it by

    from multiprocessing import *

Answer 1

With your import, you will import everything inside the multiprocessing module. I assume that you are making a call that looks something like

multiprocessing.some_function()

but since you've imported everything inside multiprocessing , it will not be in your namespace. I recommend that you do import multiprocessing and use that as your point of entry to not clutter your namespace.
