在cython记忆视图中摸索的麻烦。。。我如何在这里实现？

两个函数：一个用于创建3200万整数数组，另一个用于数百万次查找

from cpython cimport array as c_array
from array import array

def get_lut(file_location):
    cdef c_array.array lut
    with open(file_location, "rb") as f:
        lut = array("I", f.read())
    return lut

def use_lut(int[:] lut):
    // Do a whole bunch of lookups.

使用以下命令编译：

c:\Users\Michael\Documents\Poker>set DISTUTILS_USE_SDK=1
c:\Users\Michael\Documents\Poker>python setup.py build_ext -i --compiler=msvc

生成以下输出：

然而，从use_lut签名中删除int[：]类型声明可以很好地编译

这里我做错了什么？

您的代码缺少以下导入：从cpython cimport array作为c_array，从array import array-如果我替换//执行一系列查找。顺便说一句，您的代码在OSXApologies上编译得很好，请从我复制/粘贴的代码中删除这些代码。它们就在那里。运行cython handeval.pyx生成C文件，然后添加handeval.C的第12955行和它周围的几行，作为问题的上下文，可能是值得的。我怀疑诊断仍然是一个挑战…您必须使用array.array吗？我用np.arraydata，dtype=np.int32做了类似的例子
