Get number of workers from process Pool in python multiprocessing module
multiprocessing, python, threadpool
Solution
You can use `_processes` attribute:
>>> import multiprocessing
>>> pool = multiprocessing.Pool()
>>> pool._processes
8
The return value is same for `multiprocessing.cpu_count()` unless you specified process count when creating `Pool` object.
>>> multiprocessing.cpu_count()
8
Problem
I am trying to figure a way to get the number of processes directly from an instance of `multiprocessing.Pool` class in Python.. Is there a way to do it? The documentation doesn't show anything related. Thanks
