Serhiy Storchaka <storchaka+cpyt...@gmail.com> added the comment: Since contextlib._GeneratorContextManager is implemented in Python, it is unlikely that it is a culprit of the error. Do you use any third-party extensions? Likely some extension provoked the error.
Can you provide a minimal script that reproduces the issue? ---------- nosy: +serhiy.storchaka _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue32799> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
