Hi folks,
I'm trying to turn some numpy code into cython. In pure python
it's very slow, and I don't believe the task can be vectorized easily,
so I've turned to you.
The code imported fine before I tried adding the cython
modifications to it, but it ran slower than before. Now, it fails
with this error:

My setup.py:
from distutils.core import setup
from distutils.extension import Extension
from Cython.Distutils import build_ext
import numpy
setup(
ext_modules = [
Extension("cplfit", ["cplfit.pyx"],
include_dirs = [numpy.get_include(),'.'])
],
cmdclass = {'build_ext': build_ext},
)
Am I passing the wrong flags / setting the wrong variables? Or is
there some fundamental incompatibility with the 64 bit setup I have?
I can distribute the python & cython code if that helps.
Thanks,
Adam
