[Python-Dev] embedding python with numarray (original) (raw)

Using Python 2.3.3, trying to embed python with numarray, my C++ application crashes (segmentation fault) at "import_libnumarray()", (I c&p the macro, its within the macro at: PyObject *module = PyImport_ImportModule("numarray.libnumarray"); )

when I:

1.
   initalize python and numarray like:
...
   Py_Initialize();
   import_libnumarray();
...

2 .
   load another module like:

     PyObject* pModule = PyImport_Import(pName);


3.
call Py_Finalize()
and do 1. again.

The palce where it crashes is: Objects/typeobject.c line 3004: if (basebase->tp_as_sequence == NULL)

If I call import_libnumarray() only once (ie calling Py_Initialize() without import_libnumarray() the second time, I cannot use numarray:

Traceback (most recent call last): File "/usr/local/gdl/gdl/test.py", line 5, in testfun print a File "/usr/local/lib/python2.3/site-packages/numarray/numarraycore.py", line 660, in str return array_str(self) TypeError: 'NoneType' object is not callable

Any suggestions? How can numarray be restarted properly after a Py_Finalize() ? Thanks, marc
