Hi all,

On Windows 10 with Visual Studio 2017 I', trying to run the following code in x64 debug configuration:

#include <iostream>

#include <boost/python.hpp>

#include <boost/python/numpy.hpp>

namespace p = boost::python;

namespace np = boost::python::numpy;

int main()

{

    Py_Initialize();

    np::initialize();

    p::tuple shape = p::make_tuple(3, 3);

    np::dtype dtype = np::dtype::get_builtin<float>();

    np::ndarray a = np::zeros(shape, dtype);

    return 0;

}

In the line

np::initialize();

I'm getting a

Exception thrown at 0x0000000066E43B15 (python36.dll) in test.exe: 0xC0000005: Access violation reading location 0x0000000000000025. occurred

Inside boost::python::numpy::intialize() the exception is thrown when trying to execute the line:

PyObject *numpy = PyImport_ImportModule("numpy.core.multiarray");

Does anyone know why that would happen or how to debug the issue further?

I have installed all packages via pip and executed the python code as described in https://www.scipy.org/getting-started.html.

Thanks ahead!
