Loading numpy into IronPython

Question

Hi,

I've recently installed Ironpython + tools and having trouble loading external modules (numpy).

this is my test code:

import numpy
numpy.test()

when writing my simple test, intellisense can find numpy, however when it's run from vs2010, I get:

ImportException was unhandled by user code:
No module named numpy

IronPython Console output (shortened):

numpy\__init__.py line 141
numpy\add_newdocs.py line 9
numpy\lib\__init__.py line 4
numpy\lib\type_check.py line 8
numpy\core\__init__.py line 5
ImportError: No module named multiarray

the file multiarray.pyd is present in numpy\core.

I have numpy installed in my python 2.6 folder, (working). In an attempt to use it within ironpython, Following the instructions of numerous sources:

I've added "C:\Python26\Lib\" as a Search path to the project.

I've copied the site-packages, libs, include and DLLs folders from C:\Python26\ to C:\Program Files (x86)\IronPython 2.6 for .NET 4.0\

and I've added:

sys.path.append(r"C:\Python26\Lib")

to the IronPython site.py file.

I've also tried this with both x86 and AMD64 installs, including a complete reinstall of both python versions and ironpython.

Having run completely out of ideas (and the somewhat lackluster google results), I was hoping that someone here may have some suggestions.

Thanks Rabit

Answer 1

I don't believe Numpy is supported for IronPython: http://en.wikipedia.org/wiki/IronPython

Unless it's changed since that update. :(

Update: Apparently there are projects underway to get support for some of the CPython stuff which in turn would help support Numpy http://www.resolversystems.com/news/?p=17

Update 2: Apparently you can use numpy with some other open source product: http://ironpython-urls.blogspot.com/2008/08/ironclad-05-released-use-numpy-from.html

Update 3: Official link to Ironclad => http://code.google.com/p/ironclad/

Sorry, I'm not sure if this is of much help :(

Answer 2

update 3: wrong twice, ip tools and ip are frustratingly bundled together... which vs2010 doesn't like. Getting closer though.. Currently working with 2.6 for .net4 in ipy console

^^ explains that frames support is required for ironclad (something not mentioned too clearly)

also that this is potentially not fixed within the new 2.6 for .net 4, going to play with "frames" settings and/or try an older still version of ip
