[Numpy-discussion] Strange numpy.argmax behavior on object arrays in numpy 1.0.

[Tom D. <tom...@al...>]

I recently upgraded to numpy 1.0 from 1.0b5.   I noticed that
numpy.argmaxbehavior is very strange on object arrays.  See below:

(Pdb) numpy.__version__
'1.0'
(Pdb) numpy.argmax(numpy.array([2, 3], dtype=object))
0
(Pdb) numpy.argmax(numpy.array([2, 3], dtype=int))
1
(Pdb) numpy.argmax(numpy.array([2, 3], dtype=object), axis=0)
0


I would expect the argmax to behave the same on the dtype=int and
dtype=object examples but it doesn't.  Am I missing some subtelty or is this
just a bug?  1.0 is the most recent version, right?
