avalon-fsn 介绍
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
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": []
}
| 配置名称 | 配置描述 |
|---|---|
| remove_models | 不参与编译的模块 |
| remove_files | 不参与编译的文件 |

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')
纯Python

简单编译之后，性能直接就提升近6倍
