我有一个非常简单的cython代码,它使用prange
,在linux中工作正常。但是,当我尝试在Windows中执行此操作时。我遇到了一个问题,它可以编译但无法导入:
ImportError: DLL load failed: This application has failed to start because the a
pplication configuration is incorrect. Reinstalling the application may fix this
problem.
此外,在Windows中我不能from cython.parallel import threadlocal
?!奇怪...
有没有人可以指明方向?
系统工作正常: linux64 ,编译器 gcc ,包: Python 2.7,cython 0.16
系统有问题: Win64 ,编译器: MSVC VS2008 ,包: Python 2.7,cython 0.16
这是我简单的cython pyx:
cimport cython
from cython.parallel import prange
def f(int n):
cdef int i
cdef int sum = 0
for i in prange(n, nogil=True):
sum += i
print sum
这是我的setup.py:
from distutils.core import setup
from distutils.extension import Extension
from Cython.Distutils import build_ext
import numpy as np
setup(
cmdclass = {'build_ext': build_ext},
include_dirs = [np.get_include()],
ext_modules = [Extension("pcython1", ["pcython1.pyx"],extra_compile_args=['/openmp',],),]
)

由于VS2008安装程序错误,amd64_microsoft.vc90.openMP未安装到winSxS中。安装openMP运行时将解决此问题。

使用MinGW(请参阅this question正确设置mingw with cython),然后将 setup.py 更新为:
from distutils.core import setup
from distutils.extension import Extension
from Cython.Distutils import build_ext
import numpy as np
ext_modules = [Extension("convolve_cy", ["convolve_cy.pyx"],
extra_compile_args = ["-O3", "-fopenmp"],
extra_link_args=["-fopenmp"])]
setup (
name = 'performance test app',
cmdclass = {'build_ext': build_ext},
include_dirs = [np.get_include()],
ext_modules = ext_modules,
)
这是在使用Python 2.7和cython 2.0的windows7多核64位机器上工作。
