Dear list, I'm embedding Python inside a C program to pull functions from user-supplied Python modules. All is well except when the user-supplied module imports numpy. Requesting a stack trace when an exception occurs reveals the following:
--- Traceback (most recent call last): File "/Users/dpo/.virtualenvs/matrox/matrox/curve.py", line 3, in <module> import numpy as np File "/Users/dpo/.virtualenvs/matrox/lib/python2.7/site-packages/numpy/__init__.py", line 137, in <module> import add_newdocs File "/Users/dpo/.virtualenvs/matrox/lib/python2.7/site-packages/numpy/add_newdocs.py", line 9, in <module> from numpy.lib import add_newdoc File "/Users/dpo/.virtualenvs/matrox/lib/python2.7/site-packages/numpy/lib/__init__.py", line 4, in <module> from type_check import * File "/Users/dpo/.virtualenvs/matrox/lib/python2.7/site-packages/numpy/lib/type_check.py", line 8, in <module> import numpy.core.numeric as _nx File "/Users/dpo/.virtualenvs/matrox/lib/python2.7/site-packages/numpy/core/__init__.py", line 5, in <module> import multiarray ImportError: dynamic module does not define init function (initmultiarray) --- (here, "curve.py" is the user-supplied module in question.) The symbol initmultiarray *is* defined in multiarray.so so I'm wondering if anybody has suggestions as to what the problem may be here. A bit of Googling reveals the following: * The 3rd example of Section 31.2.5 of http://www.swig.org/Doc1.3/Python.html says "This error is almost always caused when a bad name is given to the shared object file. For example, if you created a file example.so instead of _example.so you would get this error." * Item #2 in the FAQ at http://biggles.sourceforge.net/doc/1.5/faq says "This is a problem with your module search path. Python is loading [multiarray].so as a module instead of [multiarray].py" But I don't have any multiarray.py. I have other multiarray.so's, but they're not in my search path. And I'm not finding any _multiarray.so with a leading underscore. So I am lead to ask: should multiarray.so really be called _multiarray.so? If not, any idea what the problem is? I'm using Python 2.7.2 compiled as a framework using Homebrew on OSX 10.6.8 and Numpy 1.6.1 installed from PyPi a day or two ago. Thanks much in advance! -- Dominique _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
