Andrew Svetlov added the comment: asyncio objects are not pickable and shouldn't be -- they are ephemeral. Like pickling open socket object doesn't make sense -- there is no possibility to restore connection to peer on unpickling. Not sure if we can do anything here. I suggest closing the is

Serhiy Storchaka added the comment: Since WeakSet never was pickleable, the difference perhaps in the use of WeakSet in asyncio. BaseEventLoop contains a WeakSet attribute since 3.6, this makes it non-pickleable. I'm not sure this is a cause of the failure. -- components: +Library (Li

Serhiy Storchaka added the comment: If the example worked on old versions of Python, perhaps this is a regression. Either WeakSet was pickleable or it was not used in that asyncio/multiprocessing use. If this is a regression in the stdlib it should be fixed. -- nosy: +fdrake, giampaol

DAVID ALEJANDRO Pineda added the comment: Now I try again with different ways to run a method with args, without args works fine to insert in the executor. I find there are big differences with file functools betwen versions 3.5.1 to 3.6.0. Here a more simple example for test the functools: ht

New submission from DAVID ALEJANDRO Pineda: Hello. I'm working in a real time data collector project. I'm using asyncio and multiprocessing (run_in_executor). In python 3.5 worked fine but in python 3.6 not, gave to me this error: "Traceback (most recent call last): File "/usr/local/lib/pyth
