You write an `extern "C"` function that calls an explicitly
instantiated version of the templated function.
extern "C" {
PyObject* my_python_function(PyObject* self, PyObject* args)
{
double *input_array;
double *output_array;
PyObject *py_output_array;
input_array = ...
output_array = ...
my_templated_function<double>(input_array, output_array);
py_output_array = PyArray_...(output_array);
return py_output_array
}
}
