Hello all, I was able to successfully embed python code into C code. The basic skeleton is something like this : In C code : PyObject *pName, *pModule, *pFunc,*pArgs,*pReturn; PyArrayObject *cusForce; Py_Initialize(); import_array(); // required while using numpy arrays in C // Call some python code // Py_Decref all the used values Py_Finalize() Py_Finalize caused segmentation faults when numpy was one of import modules [node1:05762] Failing at address: 0x1 [node1:05762] [ 0] /lib64/libc.so.6 [0x3afa630280] [node1:05762] [ 1] /usr/lib64/python2.4/site-packages/numpy/core/multiarray.so [0x2b4e950aaf37] [node1:05762] [ 2] /usr/lib64/python2.4/site-packages/numpy/core/multiarray.so [0x2b4e950dd1d0] [node1:05762] [ 3] /usr/lib64/python2.4/site-packages/numpy/core/multiarray.so [0x2b4e950e22fa] [node1:05762] [ 4] /usr/lib64/libpython2.4.so.1.0(PyObject_IsTrue+0x37) [0x2b4e8a683c77] Which could be avoided by not calling Py_Finalize. But without calling Py_Finalize(), I am having huge memory leaks as the process keeps on increasing its memory usage as I see in top. Is there any clean way of calling Py_Finalize() when using numpy.
