我试图加快答案在这里使用用Cython.我尝试编译代码(在执行此处cygwinccompiler.py解释的hack 之后),但是出错了.任何人都可以告诉我,如果这是我的代码的问题,或Cython的一些深奥的微妙？fatal error: numpy/arrayobject.h: No such file or directory...compilation terminated

以下是我的代码.提前致谢:

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] …

在我的安装中,numpy arrayobject.h位于…/site-packages/numpy/core/include/numpy/arrayobject.h.我写了一个使用numpy的简单Cython脚本:

cimport numpy as np

def say_hello_to(name):
    print("Hello %s!" % name)

我也有以下distutils setup.py(从Cython用户指南复制):

from distutils.core import setup
from distutils.extension import Extension
from Cython.Distutils import build_ext

ext_modules = [Extension("hello", ["hello.pyx"])]

setup(
  name = 'Hello world app',
  cmdclass = {'build_ext': build_ext},
  ext_modules = ext_modules
)

当我尝试构建时python setup.py build_ext --inplace,Cython尝试执行以下操作:

gcc -fno-strict-aliasing -Wno-long-double -no-cpp-precomp -mno-fused-madd \
-fno-common -dynamic -DNDEBUG -g -Os -Wall -Wstrict-prototypes -DMACOSX \
