python - ImportError importing .pyd - DLL 加载失败。 Cython

Question

我正在尝试对这段代码 (GDTest.pyx) 进行 Cythonize 处理:

cimport numpy as np
import numpy as np

DTYPE = np.float64
ctypedef np.float64_t DTYPE_t

# Generates a matrix of Dirichlet random variates of size K
# Argument alpha: J x K matrix of Dirichlet parameters
# Returns g: J x K matrix of J Dirichlet draws, each of dimension K 
# (each row sums to 1)
def GenerateDirich(np.ndarray alpha):
    assert alpha.dtype==np.float64
    cdef double fuzz = pow(10,-200)
    cdef np.ndarray g=np.zeros((alpha.shape[0],alpha.shape[1]), dtype=DTYPE)
    cdef np.ndarray gSum
    g[:,:] = np.maximum(np.random.gamma(alpha[:,:]),fuzz)
    gSum = np.sum(g,axis=1)
    gSum = gSum[:,np.newaxis]
    g = np.copy(g/(np.kron(np.ones((1,alpha.shape[1])),gSum)))
    g=np.copy(g/np.repeat(gSum,alpha.shape[1]).reshape((gSum.shape[0],alpha.shape[1])))
return g

这是我的setup.py:

from distutils.core import setup
from Cython.Build import cythonize
import numpy

setup(
    ext_modules=cythonize('GDTest.pyx'),
    include_dirs=[numpy.get_include()]
)

当我运行这条线时:

python setup.py -c mingw64 --inplace

我收到一堆警告(已弃用的 numpy API，以及一些与 _Pyx_RaiseTooManyValuesError 相关的警告)，但随后它创建了 GDTest.pyd。当我尝试导入它时，出现错误:

ImportError:DLL Load Failed: A dynamic link library (DLL) initialization routine failed.

我运行了 dependency walker，这是它所缺少的:

API-MS-WIN-CORE-KERNEL32-PRIVATE-L1-1-1.DLL

API-MS-WIN-CORE-PRIVATEPROFILE-L1-1-1.DLL

API-MS-WIN-SERVICE-PRIVATE-L1-1-1.DLL

MSVCR90.DLL

API-MS-WIN-CORE-SHUTDOWN-L1-1-1.DLL

EXT-MS-WIN-NTUSER-UICONTEXT-EXT-L1-1-0.DLL

IESHIMS.DLL

奇怪的是，如果我尝试第二次导入它(import GDTest)，它会起作用。关于如何解决此问题的任何想法？

谢谢!

我通过完全卸载 canopy 解决了我的问题。然后，我安装了 32 位版本的 anaconda 和 MS visual studio 2008 express edition。现在可以了。万岁!
