error importing VoxelizationCode.pyx about clearmap

[mgxd]

I've worked around the problem by generating the c code with
cython VoxelizationCode.pyx
then compiling the c code into .so
gcc -shared -pthread -fPIC -fwrapv -O2 -Wall -fno-strict-aliasing -I path/to/python -o VoxelizationCode.so VoxelizationCode.c

finally, I made another file VoxelizationCode.py

def __bootstrap__():
   global __bootstrap__, __loader__, __file__
   import sys, pkg_resources, imp
   __file__ = pkg_resources.resource_filename(__name__,'VoxelizationCode.so')
   __loader__ = None; del __bootstrap__, __loader__
   imp.load_dynamic(__name__,__file__)
__bootstrap__()

This allowed me to import the package
