New submission from Gerrit Holl <gerrit.h...@gmail.com>:
Pythons commandline warning filter cannot currently handle custom warning categories. See https://bugs.python.org/issue22543 I tried a workaround as suggested on Stack Overflow <https://stackoverflow.com/a/53538033/974555> to filter on a warning category defined in pandas.errors.__init__.py (DtypeWarning): PYTHONPATH=/media/nas/x21324/miniconda3/envs/py37e/lib/python3.7/site-packages/pandas/ python -Werror::errors.DtypeWarning However, this results in a Fatal Python error and core dump: Fatal Python error: init_sys_streams: can't initialize sys standard streams AttributeError: module 'io' has no attribute 'OpenWrapper' Current thread 0x00007f7bb3be76c0 (most recent call first): Aborted (core dumped) ---------- messages: 360469 nosy: Gerrit.Holl priority: normal severity: normal status: open title: Core dump when trying to use workaround for custom warning category (Fatal Python error: init_sys_streams: can't initialize sys standard streams) type: crash versions: Python 3.7 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue39419> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
