Is it just me or something is seriously wrong with new Python futures module on windows
I am on windows XP and I have problems with new Python 3.2 futures module.
It seems I am unable to get ProcessPoolExecutor
to work.
Session开发者_如何学Go example:
Python 3.2 (r32:88445, Feb 20 2011, 21:29:02) [MSC v.1500 32 bit (Intel)] on win32 Type "help", "copyright", "credits" or "license" for more information.
>>> from concurrent import futures
>>> executor = futures.ProcessPoolExecutor()
>>> def pio(x):
... print("I AM HERE")
... return True
...
>>> fut = executor.submit(pio, 5)
>>> Process Process-1:
Traceback (most recent call last):

>>> fut.running()
True
It looks like something is wrong here to me.
You have to be aware that the concurrent.future
module uses the multiprocessing
module (especially when you used the ProcessPoolExecutor
), so some functionality will not work in the interactive interpreter, read more about this here.
