Note that that setup.py doesn't include NumPy headers, which are usually
needed if numpy is cimported. Please do
import numpy
...
setup(
...
ext_modules = [Extension(..., include_path=[numpy.get_include()])]
)
The problems remain with the notebook though -- Cython, NumPy and the
Sage notebook does not work out of the box last time I tried. (It's been
a while since I tried it, but the problems didn't seem restricted to
only include path problems, but also some conflicts between the
preparsing/inserting include statements and the cimport of numpy? But
don't trust my memory here.)
