编译cython .pyx文件时出错

我对cython完全不熟悉并且正在学习它。

我有一个.pyx文件,当我尝试使用ff的ipython笔记本中的distutils模块编译它。代码:

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

setup(
    name = "functions_cython",
    ext_modules = cythonize('../utils/cython_func.pyx'), # accepts a glob pattern
)

我收到以下错误:

An exception has occurred, use %tb to see the full traceback.

SystemExit: usage: __main__.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...]
   or: __main__.py --help [cmd1 cmd2 ...]
   or: __main__.py --help-commands
   or: __main__.py cmd --help

error: option -f not recognized

当我尝试使用python setup.py build_ext --inplace setup.py中存储的相同代码以另一种方式编译它时,我收到此错误:

build_ext --inplace
Compiling cython_func.pyx because it changed.

#include "numpy/arrayobject.h"
     ^

如何解决编译?

另一个问题,根据cython文档,cython代码必须编译,与python代码不同,为什么会这样?

(这样做的目的是我应该能够将.pyx文件导入ipython笔记本。)

1 个答案:

答案 0 :(得分:2)

我能够通过在设置中添加另一个参数include_dirs=[numpy.get_include()])来解决此问题,以解决不合适的文件错误'numpy/arrayobject.h'

只需发布,以便其他人可以参考这些类型的错误。
