Ok, I figured it out. I had two sets of python libs installed, via the
Windows python installer and via vcpkg.
I hope the following items might help someone:
* the default python installation on Windows already comes with import libs
and the dlls.
* there is no need to built python with vcpkg not even for debug
configuration
* DONT set BOOST_DEBUG_PYTHON unless you want to debug python libs
* Ideally, there is no need to set PYTHONHOME and PYTHONPATH environmental
variables.

Hi all,
On Windows 10 with Visual Studio 2017 I', trying to run the following code in x64 debug configuration:
#include <iostream>
#include
#include 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! Christian
