我尝试使用优秀的pythran制作一个 python 包。
有了这个文件结构
$ tree ../proj
../proj
├── ccompile.py
├── Makefile
├── proj
│ ├── __init__.py
│ └── lib.py
└── setup.py
我的 pythran 东西在 ccompile.py 中：
$ cat ccompile.py
# pythran export get_fast_results(int[], int[][], (int, int):int dict)
def get_fast_results(mylist_of_int, myarray, dict_with_int_tuples_keys):
# do stuff update dict_with_int_tuples_keys
return dict_with_int_tuples_keys
setup.py 调用PythranExtension：
$ cat setup.py
from setuptools import setup
from pythran.dist import PythranExtension
setup(name='proj',
version=0.42,
packages=['proj'],
ext_modules=[PythranExtension("ccompile", ["ccompile.py"])],
# ext_modules=[PythranExtension("proj.ccompile", ["proj/ccompile.py"])],
zip_safe=False)
一切正常python setup.py install编译 ccompile.py 并安装.so在 egg 文件夹的根目录下::
$ tree
~/venv/lib/python2.7/site-packages/proj-0.42-py2.7-linux-x86_64.egg/
├── ccompile.py
├── ccompile.pyc
├── ccompile.so
├── EGG-INFO
│ └── ...
└── proj
├── __init__.py
├── __init__.pyc
├── lib.py
└── lib.pyc
问题是我必须手动 mv ccompile.* from
site-packages/proj-0.42-py2.7-linux-x86_64.egg/to
site-packages/proj-0.42-py2.7-linux-x86_64.egg/proj/才能从 proj 包中导入 pythran 函数::
/tmp$ python -c 'from proj.ccompile import get_fast_results as gfr; print gfr.__doc__'
Supported prototypes:
- get_fast_results(int[], int[][], (int, int):int dict)
- get_fast_results(int[], int[][].T, (int, int):int dict)
make it fast
/tmp$
如果我使用 distutils 扩展中的语法（参见
https://docs.python.org/2/distutils/examples.html#single-extension-module），例如ext_modules=[PythranExtension("proj.ccompile", ["proj/ccompile.py"])],
在 setup.py 中（在 proj 中移动 ccompile）我得到一个错误当pythran编译它时：
$ tree ../proj
../proj
├── Makefile
├── proj
│ ├── ccompile.cpp
│ ├── ccompile.py
│ ├── __init__.py
│ └── lib.py
└── setup.py
和：：
$ more setup.py
from setuptools import setup
from pythran.dist import PythranExtension
setup(...
ext_modules=[PythranExtension("proj.ccompile", ["proj/ccompile.py"])],
zip_safe=False)
我得到::
$ python setup.py install
running install
...
