Description
-
I have checked that this issue has not already been reported.
-
I have confirmed this bug exists on the latest version of pandas.
-
I have confirmed this bug exists on the master branch of pandas.
Reproducible Example
import pandas as pd
pd.Series(
[1.0, 1.0],
dtype='datetime64[ns]'
).clip(
pd.Series(
[None, 1.0],
dtype='datetime64[ns]')
)Issue Description
Clipping with columns that contain NaT values raises "TypeError: '>=' not supported between instances of 'Timestamp' and 'float'".
This can be quite confusing, particularly if you're starting with float data and casting to datetime.
Expected Behavior
Ideally the error message would read: "TypeError: '>=' not supported between instances of 'Timestamp' and 'NaT'".
