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
