New submission from Dale: I'm trying 3.6b4 on my mac (OS X 10.10.5) and when I run the following code (after doing pip install numpy and pandas) I see a 'SystemError':
>>> import pandas as pd >>> pd.to_datetime('10/31/2016') ValueError: Error parsing datetime string "10/31/2016" at position 2 The above exception was the direct cause of the following exception: Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/Users/schouten/virtualenvs/tmp/lib/python3.6/site-packages/pandas/util/decorators.py", line 91, in wrapper return func(*args, **kwargs) File "/Users/schouten/virtualenvs/tmp/lib/python3.6/site-packages/pandas/tseries/tools.py", line 430, in to_datetime return _convert_listlike(np.array([arg]), box, format)[0] File "/Users/schouten/virtualenvs/tmp/lib/python3.6/site-packages/pandas/tseries/tools.py", line 401, in _convert_listlike require_iso8601=require_iso8601 File "pandas/tslib.pyx", line 2302, in pandas.tslib.array_to_datetime (pandas/tslib.c:43278) File "pandas/tslib.pyx", line 2458, in pandas.tslib.array_to_datetime (pandas/tslib.c:41773) File "pandas/tslib.pyx", line 2416, in pandas.tslib.array_to_datetime (pandas/tslib.c:41009) File "pandas/src/datetime.pxd", line 141, in datetime._string_to_dts (pandas/tslib.c:90460) SystemError: <class 'str'> returned a result with an error set >>> sys.version says: >>> import sys >>> sys.version '3.6.0b4 (v3.6.0b4:18496abdb3d5, Nov 21 2016, 20:44:47) \n[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)]' >>> With 3.5 it works as expected: >>> import sys >>> sys.version '3.5.1 (v3.5.1:37a07cee5969, Dec 5 2015, 21:12:44) \n[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)]' >>> import pandas as pd >>> pd.to_datetime('10/31/2016') Timestamp('2016-10-31 00:00:00') >>> I know it looks like pandas might be at fault, but given that the only thing I've changed is the Python version, I'm thinking it might be exposing a 3.6 bug (or vice versa, I suppose).
