将python项目转化为so文件

1.安装gcc sudo apt-get build-dep gcc
安装cython pip install Cython

2.编译整个目录:
将需要编译的目录和setup.py放在同一层级,执行python setup.py

setup.py代码如下：

#-* -coding: UTF-8 -* -
__author__ = 'Arvin'

"""
执行前提：
    系统安装python-devel 和 gcc
    Python安装cython

编译整个当前目录：
    python py-setup.py
编译某个文件夹：
    python py-setup.py BigoModel

生成结果：
    目录 build 下

生成完成后：
    启动文件还需要py/pyc担当，须将启动的py/pyc拷贝到编译目录并删除so文件

3.生成结果:
so文件在build目录下
