avalon-fsn

avalon-fsn 是一个Python的编译构造工具，能够将你的代码Cython

使用avalon-fsn的好处

• 代码Cython化：Windows下把代码编译为pyd，Linux下把代码编译为.so，有效的保护源代码


• 获得性能提升：能够在不做任何代码级别优化的情况下，对Python代码进行性能提升

安装

pip install avalon-fsn

编译项目

avalon-fsn-build build_ext

编译完毕后，对应的文件会在./build/lib*底下

使用编译后的文件

avalon-fsn-release

执行此命令会把build目录下的编译文件替换到根目录下，仅在编译发布环境使用

##配置文件 当有定制参数的时候，可以在项目根目录下新建配置文件avalon-fsn.json

{

  "remove_models": [],

  "remove_files": []

}

    iterations = 2 ** max_depth



    for depth in range(min_depth, stretch_depth, 2):



        check = 0

        for i in range(1, iterations + 1):

            check += check_tree(make_tree(depth))



        print("%d\t trees of depth %d\t check:" % (iterations, depth), check)

        iterations //= 4



    print("long lived tree of depth %d\t check:" %

          max_depth, check_tree(long_lived_tree))



    time_end = time.time()

    print('time cost', time_end - time_start, 's')
