如何将 Python 模块与预编译的 .so
库打包在一起?具体来说,我该如何编写 setup.py
以便当我在 Python 中执行此操作时
How do I package a Python module together with a precompiled .so
library? Specifically, how do I write setup.py
so that when I do this in Python
>>> import top_secret_wrapper
不用设置LD_LIBRARY_PATH
也能轻松找到top_secret.so
?
It can easily find top_secret.so
without having to set LD_LIBRARY_PATH
?
在我的模块开发环境中,我的文件结构如下:
In my module development environment, I have the following file structure:
.
├── top_secret_wrapper
│ ├── top_secret.so
│ └── __init__.py
└── setup.py
在 __init__.py
里面,我有类似的东西:
Inside __init__.py
, I have something like:
import top_secret
这是我的 setup.py
from setuptools import setup, Extension
setup(
name = 'top_secret_wrapper',
version = '0.1',
description = 'A Python wrapper for a top secret algorithm',
url = None,
author = 'James Bond',
author_email = 'James.Bond.007@mi6.org',
license = 'Spy Game License',
zip_safe = True,
)
我确定我的 setup.py
缺少指定 top_secret.so
位置的设置,但我不确定如何执行此操作.
I'm sure my setup.py
is lacking a setting where I specify the location of top_secret.so
, though I'm not sure how to do that.
我最终做的是:
setup(
name='py_my_lib',
version=version, # specified elsewhere
packages=[''],
package_dir={'': '.'},
package_data={'': ['py_my_lib.so']},
)
这样我可以按名称导入库,并且没有其他级别的嵌套:
This way I get to import the lib by its name, and don't have another level of nestedness:
import py_my_lib
而不是
from py_my_lib_wrapper import py_my_lib
