Dear *All *I got stuck on it on wrapping c++ code which need accept numpy.ndarray as argument. The numpy.version I am using is '1.0rc1'.* *(My previous question is too massy, so I revised it. Sorry if I borthered you!) I used two ways to access numpy.ndarray, but they all reported error. ----------------------------------------------------------------------------------- 1st way: void testArray(PyArrayObject * args) { }

...

...

hello.testArray(b) Traceback (most recent call last): File "<stdin>", line 1, in ? Boost.Python.ArgumentError: Python argument types in hello.testArray(numpy.ndarray) did not match C++ signature: testArray(PyArrayObject*)

2nd way: void testArray(PyObject * args) { PyObject *input; PyArrayObject *array; if (!PyArg_ParseTuple(args, "O", &input)) printf("getting input failed!\n"); else printf("getting input sucess!\n"); }

...

...

import hello import numpy c = numpy.arange(25).reshape((5,5)) d = hello.testArray(c); getting input failed! d SystemError: new style getargs format but argument is not a tuple

Any suggestion will be appreciated. Thanks! -- Qinfeng(Javen) Shi Research School of Information Sciences and Engineering Australian National University Locked Bag 8001 Canberra ACT 2601
