示例cython代码似乎可以正确编译，但是;始终无法加载.pxd，如下所示：
%%cython
cimport cython
from libc.math cimport exp, sqrt, pow, log, erf
@cython.cdivision(True)
cdef double std_norm_cdf(double x) nogil:
return 0.5*(1+erf(x/sqrt(2.0)))
@cython.cdivision(True)
def black_scholes(double s, double k, double t, double v,
double rf, double div, double cp):
"""Price an option using the Black-Scholes model.
s : initial stock price
k : strike price
t : expiration time
v : volatility
rf : risk-free rate
div : dividend
cp : +1/-1 for call/put
"""
cdef double d1, d2, optprice
with nogil:
d1 = (log(s/k)+(rf-div+0.5*pow(v,2))*t)/(v*sqrt(t))
d2 = d1 - v*sqrt(t)
optprice = cp*s*exp(-div*t)*std_norm_cdf(cp*d1) - \
cp*k*exp(-rf*t)*std_norm_cdf(cp*d2)
return optprice

在正确的目录中找到cython_magic_f60db＆lt; ...＆gt; .pyd。没有给出其他细节。它似乎不是系统内存耗尽。
感谢您的帮助。虽然我看到有几个人没有遇到类似的问题，但似乎没有人完全回答。
PS。使用具有python 2.7级别的Anaconda IPython运行相同的cython单元...在这种情况下，发生了相同的错误，但是;生成了以下添加错误消息...

ImportError: DLL load failed: A dynamic link library (DLL) initialization routine failed.
上述故障与python 3.4完全相同，只是错误指示ImportError并指出DLL初始化例程有问题。
我检查了cython的源代码，但没有发现标准链接pragma指示dll main。
答案 0 :(得分：0)
将问题隔离到Anaconda的python包（2.7＆amp; 3.4）中运行mingw c ++的已知错误之后。我找到了如何安装Microsoft C ++ for Python 2.7（MS免费）的说明，并使cython能够使用distutils包在Anconda（2.7测试版）中成功加载和运行更新。
