问题描述
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.
推荐答案
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
