I ultimately want to access the total number of bytes in a PyArrayObject through a C++ program. I cannot seem to do it without sefaulting. All of the following yields a segfault: my_array->descr->subarray->shape my_array->dimensions PyArray_SHAPE(my_array) PyArray_DIMS(my_array) PyArray_ITEMSIZE(my_array) and of course... PyArray_NBYTES(my_array) I am working from within sage if that makes any difference. Is there a way to iterate over an array from within C++ without knowing the number of bytes in the array (and using strides--which oddly enough do not result in a segfault), or iterating over each dimension? Please point me in the right direction. There must be a way or else the entire software suite would not work. Thanks, Alex Eftimiades
