Numpy C-Api example gives a SegFault

Question

I\'m trying to understand how the Python C- Api works, and I want to exchange numpy arrays between Python and a C Extension.

So, I started this tutorial: http://dsnr

Answer 1

Your init function for the module needs to call

import_array();

after

(void) Py_InitModule("trace", TraceMethods);

It mentions this in the tutorial near the top, but it is easy to miss. Without this, it segfaults on PyArray_ContiguousFromObject.
