So I'm trying to create a boost python module that simply creates and returns a numpy array, but the function crashes (sometimes) and it doesn't ever seem to crash on Python 2.
Here's the source code I made: #include <boost/python.hpp> #include <numpy/ndarrayobject.h> using namespace boost::python; object create_numpy_array() { npy_intp dims = 1; long* data = new long[1]; data[0] = 1; PyObject* obj = PyArray_SimpleNewFromData(1, &dims, PyArray_LONGLTR, data); boost::python::handle<> handle(obj); boost::python::numeric::array arr(handle); return arr.copy(); } BOOST_PYTHON_MODULE(create) { import_array(); numeric::array::set_module_and_type("numpy", "ndarray"); def("numpy_array", &create_numpy_array); } using a simple python script to test: import create print(create.numpy_array()) The stack trace indicates that the crash occurs on a boost::python::handle destructor trying to decrease the ref count of a PyObject with a ref count of 0. I've tried this on both Windows 7 and Ubuntu 16.04 both 64-bit. Thank you.
