As I suspected, datetime not recognizing numpy.int_ as a valid input is a numpy issue. Unlike regular int subclasses, numpy.int_ does not have Py_TPFLAGS_INT_SUBCLASS flag set: >>> numpy.int_.__flags__ & (1<<23) 0 >>> class foo(int): pass ... >>> foo.__flags__ & (1<<23) 8388608 What python can improve in this area is documentation. See issue9307.
