-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I work on a 64bit machine with 64bits enable fedora on it. I just discovered that numpy.int on the python part are 64bits ints, while npy_int in the C api are 32bits ints. I can live with it, but it seems to be different on 32bit machines, hence I wonder what is the right way to do when retrieving an array from python to C. Here is what I use now: data_pyarray = (PyArrayObject *)PyArray_ContiguousFromObject(data_list, PyArray_INT, 1, 2); but that implies that I send np.int32 arrays to the C part. Should I use longs instead ?
