【问题描述】:
我对 cython 完全陌生,目前正在学习它。
我有一个 .pyx 文件,当我尝试使用 ipython 笔记本中的 distutils 模块编译它时,带有 ff.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 和存储在 setup.py 中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.

如何解决编译问题?
另一个问题,根据 cython 文档,cython 代码必须与 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 notebook。)
