Importing with boost python

Question

Whether I import like this:

numpy_module = bp::import("numpy");

or like this:

numpy_module = bp::scope().attr("numpy");

I get

terminate called after throwing an instance of 'boost::python::error_already_set'

I didn't have a problem with Python 2.7, but after upgrading to Python 3.1, this strange exception crops up.

Answer 1

Got it: I needed to compile Boost for Python31.
