cannot find numpy 1.2 for python 2.6 on window

Hello, I recently upgraded to python 2.6. I cannot seem to find the appropriate numpy install file. I tried to make use of the .exe built for python 2.5 but the installer hung. Any suggestions? Regards, Daniel

Right, you can't use a binary installer meant for Python 2.5 with
Python 2.6. The binaries aren't compatible. If you do not want to
build from source, you will have to wait for the volunteer
binary-builders to get around to making a Python 2.6 installer.

Hi Daniel,

Last I heard, there are still some things that need to be ironed out
for NumPy on Python 2.6, so you will probably have to stick with 2.5
for a while.  (Somebody please correct me if I'm wrong and there's an
imminent release for 2.6 coming up ;)

Cheers,
Alan

Re: cannot find numpy 1.2 for python 2.6 on window

Hi Alan,

I've been using numpy with 2.6 on amd64 for about 3 months no problem and far more stable on 64-bit than the same combination with 2.5.

Daniel, just download the source and compile it yourself. You need to use VS 9.0 for best compatibility with Python and I haven't yet sorted out fast blas I've just been using the internal numpy one.

One thing which was a relatively major stopper was nose, our test
infrastructure, was not 2.6 compatible, but that has just changed. I
will look on windows to see if 1.2 can be built with 2008 express,

Re: cannot find numpy 1.2 for python 2.6 on window

Hi David,

Yeah nose was an issue, thanks for letting me know about nose compatibility being sorted that's good news as I use it a bit with my testing.

I last built 1.1.1 with express for 32bit it went fine (although I think you do have to comment out , I was also able to compile with 2008 full for 64-bit platform, my next goal is to see if i can sort out blas etc. external libs on 64bit.

From the "Installation info" thread around the 30th May I had reported the one oddity I  had encountered with the VS compiler

At the time I had tried to send further output following a checkout, but couldn't get it to post to the list, I think the message was too big or something. I will probably be having a go with 1.2.0, when I get some time. I'll let you know how it goes.

Cheers,

Hanni

That's the major difficulty: no open source blas/lapack (that I am aware
of) are buildable with MS compilers, and there is no official open
source compiler (mingw) on 64 bits. Also, cygwin itself is not available
in 64 bits (only available on WOW, the windows subsystem to run 32 bits
on 64 bits OS).

Atlas, in particular, is not buildable for 64 bits windows AFAIK.

I did some heavy refactoring for the above problems, and it should be
now easier to handle (in the trunk). I could build 1.2.0 with VS 2008
express on 32 bits (wo blas/lapack), and there are some test errors -
albeit relatively minor at first sight. I have not tried on 64 bits.

cheers,

David
