BUG: Series.__repr__ crashing with tzlocal() #24310
Description
Encountered while writing tests for PR to #23833, where I wanted to use tz_aware_fixture for testing promotions of datetimes with tz. The following is an equivalent minimal example, but constructed directly.
>>> import pandas as pd >>> from dateutil.tz import tzlocal >>> from pandas.core.dtypes.dtypes import DatetimeTZDtype >>> dtype = DatetimeTZDtype(tz = tzlocal()) >>> s = pd.Series([10 ** 9], dtype=dtype) The constructor passes, but worryingly, already the repr of s fails with a huge stacktrace:
>>> s Traceback (most recent call last): [~130 lines of stacktrace] OSError: [Errno 22] Invalid argument Same goes for s[0].
The underlying values are still there though:
>>> s.values array(['1970-01-01T00:00:01.000000000'], dtype='datetime64[ns]') >>> s._data SingleBlockManager Items: RangeIndex(start=0, stop=1, step=1) DatetimeTZBlock: 1 dtype: datetime64[ns, tzlocal()] This seems like a pretty serious regression to me. @mroeschke @jbrockmendel @jreback @TomAugspurger @jorisvandenbossche
