can not import numpy in boost-python

问题

I am trying out boost-python. However, even a simple hello world doesn't work.

#define BOOST_PYTHON_STATIC_LIB
#include <boost/python/detail/wrap_python.hpp>
#include "numpy/arrayobject.h"
#include <boost/python.hpp>

 void init_numpy()
{
  import_array();
}

 int main()
 {
     Py_Intialize();
     init_numpy();       

 }

It gives error

ImportError: numpy.core.multiarray failed to import

But if I open my IPython, and run import numpy.core.multiarray, it runs fine. What part am I getting worng?

回答1:

I solved the problem by by realizing that the Anaconda2 on my windows was not registered during installation (even sys.path is the same as that in IPython), I uninstalled it and reinstalled it, during installation I chose to register in the windows, now my code is working fine.
