    I'm having a problem ........

    I've stripped all my code to help isolate the problem.

    Its seems to be with importing numarray when python is embedded in C.

    I have a simple C program it Opens Python imports a script and
    then Closes Python

    like so .......

    int main(int argc,char *argv[])
    {

    int count = 0;
    PyObject *pmod;

    while ( count < 10)
    {

    /*
    ** Initialize Python
    */

    Py_Initialize();
    printf("\nOpen Python ---- >");

    pmod = PyImport_ImportModule("test");

    Py_DECREF(pmod);

    /*
    ** Close Python
    */

    Py_Finalize();
    printf("\n<---- Closed Python");


    /*
    ** Do this 10 times !
    */
    count++;

    }
    getchar();
    return(0);

    }

    and thats it !

    The script it calls is test.py its very simple , it imports numarray
    and then returns. like so .......

    -----------------------
    test.py
    -----------------------
    #Imports
    from numarray import *

    def test_func():
    return (99)
    -----------------------
    end of file
    -----------------------


    The first time it is called from my C code
    it all works fine ! ( but only the first time ! )

    In the second iteration above test .c crashes

    It has something to do with importing numarray.
    Beacase if you comment out the import line i.e

    -----------------------
    test.py
    -----------------------
    #Imports
    # Commented out !
    #from numarray import *

    def test_func():
    return (99)
    -----------------------
    end of file
    -----------------------

    its scrolls through the while loop and works fine.

    Its all very odd . any ideas ?


    I'm using Python 2.3.3 and Python 2.3 numarray - 0.8

    Thanks in advance
