Also note that there are known problems with using the "fork" start method of multiprocessing on macOS. As of Python 3.8, the default start methord on macOS is now "spawn": https://docs.python.org/3.9/library/multiprocessing.html#contexts-and-start-methods Try using "spawn" and/or upgrade to a more recent version of Python 3 (3.9.1 is current). ---------- nosy: +ned.deily _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue42850> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
