How can I use Numerical Python with Python 2.6

Question

I'm forced to upgrade to Python 2.6 and am having issues using Numerical Python (Numpy) with Python 2.6 in windows. I'm getting the following error...

Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    from numpy.core.numeric import array,dot,all
  File "C:\svn\svn_urbansim\UrbanSimDev\Builds\working\urbansim\Tools\Python26\lib\site-packages\numpy\__init__.py", line 39, in <module>
    import core
  File "C:\svn\svn_urbansim\UrbanSimDev\Builds\working\urbansim\Tools\Python26\lib\site-packages\numpy\core\__init__.py", line 5, in <module>
    import multiarray
ImportError: Module use of python25.dll conflicts with this version of Python.

It appears that the existing module is trying to use the python25 dll file. Is there any way I can tell it to use the python26 dll instead without modifying the source code?

Thanks in advance for all your help!

Answer 1

how did you install it? numpy doesn't currently have a python 2.6 binary.

if you have LAPACK/ATLAS/BLAS etc and a development environment you should be able to compile numpy from sources. otherwise i think you're stuck with using python 2.5 on windows if you need numpy.

the next version of numpy should have a 2.6 binary, and it's likely to be out within the next month or so.

[edit] it appears that a pygame developer created a numpy 1.2.1 binary for python 2.6 on windows, available here.

Answer 2

NumPy 1.3.0 is available for Python 2.6 now.
