Hi Adrian, I don't think you should be doing both "import_array()" and "import_libnumeric()". Those should be roughly equivalent. If you're using only the Numeric compatible API (no NA_ functions) then do: #include "numarray/arrayobject.h" ... and later in your init function: import_array(); just like Numeric. If you also need some of the NA_ functions, then look at Src/_dotblas.c or Src/_numarraymodule.c for how to interface with both native and numeric compatible interfaces at the same time. If you only need NA_ functions, look at Src/_ndarraymodule.c. Regards, Todd On Fri, 2005-05-27 at 18:37 -0700, Adrian E. Feiguin wrote:
Hi Todd,
Thank you for your reply. I have a completely new installation, there are no conflicts with previous installations. I found that the problem is in import_libnumeric in libnumeric.h. It seems that the libnumeric_API is not initialized because it doesn't pass the line:
PyObject *module = PyImport_ImportModule("numarray.libnumeric"); \ if (module != NULL) { \
Any ideas? Thank you again, <ADRIAN>

Hi! I'm the lead developer of scigraphica (SG) http://scigraphica.sourceforge.net and I'm using python and numarray to parse math. SG is built on top of libscigraphica, and libscigraphica has all the python code. I've been using an old version 0.6.1, and everything worked fine. After switching to 1.6.2the program crashes. I'll give you some info to see if you can tell me what's wrong:
I'm using: #define PY_ARRAY_UNIQUE_SYMBOL PyArrayXXX #include
and in the code: import_libnumeric(); import_array();
object=PyRun_String ("from numarray import *", Py_single_input, main_dict, sg_dict);
(I noticed that you have to add import_libnumeric now)
In general, this is not true.
Paradoxically, if you're using the numeric compatible API, import_array() is all you need to do. If you're using both the numarray native and numeric compatible APIs, then you need to import_libnumarray() and import_libnumeric().
The gdb output is:

Look that in #4 object=0x80bda3c, and in #3 op=0x0. Any hints?
numarray-0.6.1 is very old so in order to transition to numarray-1.3.2 you should:
a. completely delete your numarray installation
b. reinstall numarray
c. rebuild and reinstall any extensions based on numarray.
My guess is that either you have overlapping/conflicting numarray installations or you have extensions from numarray-0.6.1 trying to run against numarray-1.3.2.
