Ronald Oussoren <ronaldousso...@mac.com> added the comment:
The default start method for multirprocessing was changed from "fork" to "spawn" on macOS. This was done because the "fork" method can easily be triggered into causing hard crashes (on macOS), in particular when the parent proces has called higher-level systemen APIs. The "spawn" method requires pickling the data and callable passed to the child proces, and that's not supported for lambda's. ---------- components: +macOS nosy: +ned.deily, ronaldoussoren _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue46871> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
