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:

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
Traceback (most recent call last):

Old question but I ran into this because I had a very similar issue with numpy.

It turns out I had a directory named logging as a sibling of the script I was trying to run. So the problem was a simple naming collision between my local project folder and the logging module numpy expected to find. Renaming the project logging folder solved the issue for me.

Looking at OP's error message, I suspect this was the case for them as well.
