Thanks for copying me, Aron. Hi Dinesh, I have a github project which demonstrates how to use numpy with freeze. The project's readme includes more information: https://github.com/patmarion/NumpyBuiltinExample It does require a small patch to CPython's import.c file. I haven't tried posted this patch to the CPython developers, perhaps there'd be interest incorporating it upstream. Pat On Wed, Mar 13, 2013 at 12:08 AM, Aron Ahmadia wrote:

Pat Marion at Kitware did some work on this, I'm pinging him on the thread.

** Does that mean numpy won't work with freeze/create_executable type of tools or is there a workaround?

multiarray is an extension module that lives within numpy/core, that is, when, "import multiarray" is called, (and it's the first imported extension module in numpy), multiarray.ext (ext being dll on Windows I guess), gets dynamically loaded.

"No module named multiarray" is indicating problems with your freeze setup. Most of these tools don't support locally imported extension modules.

Does this help you get oriented on your problem?

** I've been using Numpy/Scipy for >5 years so know a little on how to get around them. Recently, I've needed to either freeze or create executables with tools such as PyInstaller, Cython, Py2exe and others on both Windows (XP 32-bit, 7 64-bit) and Ubuntu (12.04) Linux (64-bit). The test program (which runs perfectly with the Python interpreter) is very simple:

import numpy

def main(): print numpy.array([12, 23, 34, 45, 56, 67, 78, 89, 90]) return

if __name__ == '__main__': main()

The software versions are Python 2.7.3, Numpy 1.7.0, and Scipy 0.11. The "import numpy" causes an "ImportError: No module named multiarray". After endless Googling, I am none the wiser about what (really) causes the ImportError let alone what the solution is. The Traceback, similar to others found on the web, is:

Traceback (most recent call last): File "test.py", ... File "C:\Python27\lib\site-packages\numpy\__init__.py", line 154, in <module> import add_newdocs File "C:\Python27\lib\site-packages\numpy\add_newdocs.py", line 9, in <module> from numpy.lib import add_newdoc File "C:\Python27\lib\site-packages\numpy\lib\__init__.py", line 4, in <module> from type_check import * File "C:\Python27\lib\site-packages\numpy\lib\type_check.py", line 8, in <module> import numpy.core.numeric as _nx File "C:\Python27\lib\site-packages\numpy\core\__init__.py", line 5, in <module> import multiarray ImportError: No module named multiarray.

Could someone shed some light on this - please? Thx.
