Cython fatal error C1083: 无法打开包括文件: “numpy/arrayobject.h”: No such file or directory

python setup.py build_ext --inplace编译时报错如下：

解决方法：

添加 include_dirs=[np.get_include()]

添加后的setup.py如下：

from distutils.core import setupfrom distutils.extension import Extensionfrom Cython.Distutils import build_extimport numpy as npsetup(cmdclass={'build_ext': build_ext},ext_modules=[Extension('calculate', ['cythonfnS.pyx'])],include_dirs=[np.get_include()])
