[Numpy-discussion] segv PyArray_Check

[Burlen Loring]

Hi,

I'd like to add numpy support to an existing code that uses swig. I've 
changed the source file that has code to convert python lists into 
native data from c to c++ so I can use templates to handle data 
conversions. The problem I'm having is a segfault on PyArray_Check 
called from my c++ source. Looking at things in the debugger the 
argument passed to it is indeed an intialized python list, my swig file 
has import_array() in it's init, and I've verified that it is getting 
called. adding a function in my c++ source to call import_array() a 
second time prevents the segfault. Could anyone explain why I need the 
import_array() in both places? If that's the correct way to handle it?

Thanks
Burlen
