Porting numpy to Python3
Are there plans to port numpy to Python3? In particular, when will the packages of Linear Algebra (viz matrix inversion) be available in Python 3 compatible modules. Because of the importance of numpy in many scientific endeavours is so great, information of the availability in Python 3 mode is very important and will be greatly appreciated.

Hi correct me if I am wrong, I thought there is package ported for python 3.1 already? On 25 Feb 2011 10:07, "Algis Kabaila" <akabaila@pcug.org.au> wrote: Are there plans to port numpy to Python3?

If there is, then its great news (for me). Where can I check it out? Thanks for responding - Al. On Friday 25 February 2011 13:14:31 Shao Hong wrote:

Python 3.1+ support occurred with numpy 1.5 that was released last year (2010-08-31) - 1.5.1 is the current release. scipy 0.9 due very soon (release candidates are available at http://sourceforge.net/projects/scipy/) also supports Python 3 except for weave module. Bruce

Bruce, The link http://sourceforge.net/projects/scipy/ responds with "Whoops, we can't find that page". I use Linux kubuntu 10.10 ("Maverick Meerkat") OS and installed numpy with lapac from the ubuntu binaries. As ubuntu 10.10 was released on 2010-10-10 10:x the version on numpy is probably earlier than 1.5, so presumably I have to either wait a couple of months for the next ubuntu release or install from source. Bruce, can you tell me how can I check the version of installed numpy? There probably is a __version__ or something like that which would enable to verify. Thanks for the answer - I unsuccessfully googled for the answer; I also recall my much earlier enquiries when the replies did not shed much light on the possible release date. Your reply is very much appreciated - thank you! Al. -- Algis http://akabaila.pcug.org.au/StructuralAnalysis.pdf

Al. PS: a little investigation shows that my version of numpy is 1.3.0 and scipy is 0.7.2 - so ubuntu binaries are way behind the "bleeding edge"... Al. -- Algis http://akabaila.pcug.org.au/StructuralAnalysis.pdf

... and built for the system Python (2.6), so even if the Ubuntu binaries were more up to date you'd need to build your own Numpy for Python 3. Cheers, Scott

I just build numpy and scipy from source so I do not know how you get Python 3 or which Ubuntu versions include recent numpy versions (there is a upcoming release that will probably contain a more recent numpy). It is very easy to install numpy and scipy from source on Linux although it is important that Blas/Lapack/Altas are built and installed correctly (I just use my distro's package). Please see the following link for more details: http://www.scipy.org/Installing_SciPy/Linux There was also a recent post on the list as well. Bruce

Bruce, Thank you for the information. I had a look at the URL that you gave (Actually, I had already seen it in my wanderings on internet.) For me it is very important to hear from the users' perspective how easy or hard the installation was. Python 3 is readily available in most distros, certainly in ubuntu, so that is not a problem. In fact in ubuntu Python 2.6 happily coexists with Python 3.1 for one and the same user. Thank you for your help - greatly appreciated.
