New submission from Nathan Goldbaum <nathan12...@gmail.com>:
As of https://github.com/python/cpython/pull/7076, it looks like at least the C implementation of pickle.load expects the file argument to implement readinto: https://github.com/python/cpython/blob/ffd9753a944916ced659b2c77aebe66a6c9fbab5/Modules/_pickle.c#L1617-L1622 This is a change in behavior relative to previous versions of Python and I don't see it mentioned in PEP 574 or in the pull request so I'm not sure why it was changed. This change breaks some PyTorch tests (see https://github.com/pytorch/pytorch/issues/32289) and, at least one PyTorch user, although I don't have full details there. I can try to fix this on the PyTorch side but I first want to check that this was an intentional change on the Python side of things. ---------- components: Library (Lib) messages: 362242 nosy: Nathan.Goldbaum priority: normal severity: normal status: open title: pickle.load expects an object that implements readinto versions: Python 3.8 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue39681> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
