[Numpy-discussion] numarray bug: dot product between 2x2 and 3x2x3 on Mac different from PC

[Sebastian H. <ha...@ms...>]

Hi!
This is what I got:
>>> import numarray as na
>>> na.__version__
'1.4.0'
>>>bbb=3Dna.zeros((2,3,3), naFloat32)
>>>bbb[0,:,:]=3D1
>>>bbb[1,:,:]=3D2
>>>ccc=3Dna.transpose(bbb,(1,0,2))
>>>d=3Dna.array([[1,0],[0,1]])
>>>na.dot(d,ccc)
[[[ 1. =A01. =A01.]
=A0 [ 1. =A01. =A01.]
=A0 [ 1. =A01. =A01.]]

=A0[[ 2. =A02. =A02.]
=A0 [ 2. =A02. =A02.]
=A0 [ 2. =A02. =A02.]]]

This is on a PC (Windows or Linux):

But if you do the same thing on Mac, the result will be:
[[[ 1. 1. 1.]
=A0 [ 2. 2. 2.]
=A0 [ 1. 1. 1.]]

=A0[[ 2. 2. 2.]
=A0 [ 1. 1. 1.]
=A0 [ 2. 2. 2.]]]

Can someone confirm this ?
(the new numpy on windows also gives the first result)

Thanks,
Sebastian Haase
