np.ndarray[object] - Timedelta raises

See original GitHub issue

arr = np.array([pd.Timestamp.now(), pd.Timedelta('2D')])

>>> arr - pd.Timedelta('1D')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unsupported operand type(s) for -: 'numpy.ndarray' and 'Timedelta'

It should attempt to operate element-wise.

how should I go about the fix?

Take a look at the code block Joris quoted above. At the moment that lets ‘m’ and ‘M’ dtypes through but stops everything else. The fix will involve letting ‘o’ dtypes through (and making sure they are handled correctly)

Ah! 🤦‍♂️ yea I missed that part in the example. I repro’d the bug with that on master and latest pip. So with this then how should I go about the fix? It’s not operating element wise on the array because the timedeltas.pyx isn’t returning that it is a timedelta correctly? or…?
