BUG: DataFrame(data=[None, 1], dtype='timedelta64[ns]') raises ValueError: Buffer has wrong number of dimensions · Issue #60064 · pandas-dev/pandas (original) (raw)

Pandas version checks

• 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 main branch of pandas.

Reproducible Example

import pandas as pd df = pd.DataFrame([None, 1], dtype='timedelta64[ns]')

Issue Description

The error message doesn't tell the user what to do differently. Also, it's possible that there shouldn't be an error at all.

Expected Behavior

I think this should be allowed, in which case the resulting series would look like

                          0
0                       NaT
1 0 days 00:00:00.000000001

If it's not allowed, the error message should be clearer.
