一、python项目转化为so文件

示例：。

1.引入库

代码如下（示例）：

# -*- coding:utf-8 -*-
# author: cbj
# datetime: 2024/7/8 9:02
# @File: setup3.py
# -*- coding:utf-8 -*-
# author: cbj
# datetime: 2024/7/5 16:45
# @File: 134打包python项目so文件3.py.py

# -* -coding: UTF-8 -* -

"""
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
