```import numpy as np
import scipy as sp
cimport numpy as np
cimport cython

cdef inline np.ndarray[np.int, ndim=1] fbincount(np.ndarray[np.int_t, ndim=1] x):
cdef int m = np.amax(x)+1
cdef int n = x.size
cdef unsigned int i
cdef np.ndarray[np.int_t, ndim=1] c = np.zeros(m, dtype=np.int)

for i in xrange(n):
c[<unsigned int>x[i]] += 1

return c

cdef packed struct Point:
np.float64_t f0, f1

@cython.boundscheck(False)
def sparsemaker(np.ndarray[np.float_t, ndim=2] X not None,
np.ndarray[np.float_t, ndim=2] Y not None,
np.ndarray[np.float_t, ndim=2] Z not None):

cdef np.ndarray[np.float64_t, ndim=1] counts, factor
cdef np.ndarray[np.int_t, ndim=1] row, col, repeats
cdef np.ndarray[Point] indices

cdef int x_, y_

_, row = np.unique(X, return_inverse=True); x_ = _.size
_, col = np.unique(Y, return_inverse=True); y_ = _.size
indices = np.rec.fromarrays([row,col])
_, repeats = np.unique(indices, return_inverse=True)
counts = 1. / fbincount(repeats)
Z.flat *= counts.take(repeats)

return sp.sparse.csr_matrix((Z.flat,(row,col)), shape=(x_, y_)).toarray()```

```from distutils.core import setup, Extension
from Cython.Build import cythonize
import numpy

setup(
ext_modules=[
Extension("my_module", ["my_module.c"],
include_dirs=[numpy.get_include()]),
],
)

# Or, if you use cythonize() to make the ext_modules list,
# include_dirs can be passed to setup()

setup(
ext_modules=cythonize("my_module.pyx"),
include_dirs=[numpy.get_include()]
)    ```

```import numpy
import pyximport
pyximport.install(setup_args={"script_args":["--compiler=mingw32"],
"include_dirs":numpy.get_include()},
