Although I do recall vaguely that some numpy int types behaved differently to others... |
Maybe some time ago in numpy? Both on latest numpy and v1.11 (latest supported verson) it works for all numpy int types, >>> import numpy as np
>>> import numbers
>>> isinstance(np.int_(2), numbers.Integral)
True
>>> isinstance(np.intc(2), numbers.Integral)
True
>>> isinstance(np.int64(2), numbers.Integral)
True
>>> isinstance(np.uint8(2), numbers.Integral)
True |

Closes #5786
On the discussion whether,
should be used for testing integer dtype (including
np.integer), a better choice is to useisinstance(x, numbers.Integral)as mentionned in #5786 (comment)
