Unknown option argument: "--multiprocessing-fork"

[Yggdroot]

On Windows vim version 7.4.1923.

To reproduce:
:py from multiprocessing import Pool
:py p = Pool(4)

It seems vim does not support multiprocess of python, how can it be fixed?

This is a problem of the multiprocess package of Python,
as it seems to assume to always be running in python and
not in some embedded application.

No problem Vim can fix.

Is there any way to work around it?

How about using multiprocessing.set_executable()?
https://docs.python.org/2/library/multiprocessing.html#multiprocessing.set_executable

[char101]

You need the python executable, then set sys.executable/use multiprocessing.set_executable() as suggested by k-takata above to it before creating the pool.

py import sys; sys.executable = 'path to python/python.exe'
py from multiprocessing import Pool
py p = Pool(4)
