Re: [Numpy-discussion] [ANN] numscons 0.3.0 release

Hi all, I don't know much about what are these scons are, if it's something essential (as it seems to be from amount of mailing list traffic) why can't it be just merged to numpy, w/o making any additional branches? Regards, D. David Cournapeau wrote:

[Numpy-discussion] numscons, available as python egg

Hi, Sorry for the flooding, but I finally managed to build an egg and put it on the web, so numscons is available as an egg, now. You should be able to install it using easy_install, e.g easy_install numscons should work. cheers, David ___

Re: [Numpy-discussion] [ANN] numscons 0.3.0 release

Hi, I've attached the build logs. I noticed that, for atlas, you check for atlas_enum.c - but do you in fact need this for the build? Now. I just wanted one header specific to atlas. It looks like not all version of ATLAS install this one, unfortunately (3.8, for example).

[Numpy-discussion] tensordot bug?

Is this a bug? In [21]: a = ones((2,2)) In [22]: b = ones((2,2,2,2)) In [23]: tensordot(a, tensordot(b, a, 2), 2) Out[23]: array(16.0) It seems to me that consistency with the dot product would require a scalar result, not a 0-dim array. Also, do we have a plain old tensor product? Outer
