Cython with Numpy / AttributeError: 'module' object has no attribute 'Handler'

I want to use Numpy in Cython, but encountered the following error. This error happens even if I run the simple code, so it should be an issue related to importing Numpy.

My environment:

• OS X Yosemite
• Python 3.4.3

setup.py:

import numpy as np
from distutils.core import setup
from Cython.Build import cythonize

setup(
        name = 'my_code',
        ext_modules = cythonize('my_code.pyx'),
        include_path = [numpy.get_include()]
)

my_code.pyx:

cimport numpy as np

cdef int a 

Execute in Terminal:

$ python3 setup.py build_ext --inplace
