datetime comparison from pandas.core.seroes.Series to numpy.datetime64 fail for pandas 0.21

[zippeurfou]

Code Sample, a copy-pastable example if possible

pandas 0.20.3

import pandas as pd
rng = pd.DataFrame({ "A" : pd.date_range('1/1/2011', periods=720, freq='H')})
myvar = rng["A"] < rng["A"].values[3]

Works.

pandas 0.21

exact same code:

I am not sure why this would fail now?
Note: it might be fixed in #18188

[zippeurfou]

Closing as it works with the master version

[jorisvandenbossche]

We should still make sure this works with 0.21.1

[jreback]

this is all well tested in #18188 with almost exactly this example. I see no reason to have this issue open.

[jorisvandenbossche]

Of course not, I was just reopening to ensure this was the case :-) (I didn't search yet where it could have been fixed)
