BUG: Docs won't build (Unexpected warning in `user_guide/timeseries.rst`)

Thanks @melissawm. But this is odd - I don't know what :okwarning: would do to resolve the issue if you're not seeing a warning. I'd be hesitant to add such a line when we don't see the failing on the CI without understanding further.

The UserWarning for pd.to_datetime(pd.Series(["Jul 31, 2009", "Jan 10, 2010", None])) seems to be strange because no warning occurs when I directly run this code in ipython.

This suggests to me you are using two different pythons when you build docs vs when you run in ipython. When you build and install pandas, what python is used?

@rhshadrach
I directly run the commands python make.py and ipython in the same conda environment. I have checked that they use the same python.

$ which ipython
/home1/hhz/miniconda3/envs/pandas_main/bin/ipython
$ which python
/home1/hhz/miniconda3/envs/pandas_main/bin/python
$ cat /home1/hhz/miniconda3/envs/pandas_main/bin/ipython
#!/home1/hhz/miniconda3/envs/pandas_main/bin/python
# -*- coding: utf-8 -*-
import re
import sys
from IPython import start_ipython
if __name__ == '__main__':
    sys.argv[0] = re.sub(r'(-script\.pyw|\.exe)?$', '', sys.argv[0])
    sys.exit(start_ipython())

Very odd. I would suggest to try recreating your environment, but from the commands above I believe you've already done that.

Hi all, I am getting the same issue. Adding :okwarning: to this block

pandas/doc/source/user_guide/timeseries.rst

Lines 199 to 204 in ec3eddd

	.. ipython:: python
	pd.to_datetime(pd.Series(["Jul 31, 2009", "Jan 10, 2010", None]))
	pd.to_datetime(["2005/11/23", "2010/12/31"])

solves the issue for me. I'm happy to submit a PR if that's the acceptable solution. Cheers!

@melissawm - If you run this code on its own (outside building the docs), what's the warning you're seeing?

[melissawm]

Here you go, no warnings:
