add data files to python projects setup.py

Question

I have a project like this:

├── CHANGES.txt ├── LICENSE ├── MANIFEST.in ... ├── docs │   └── index.rst ├── negar │   ├── Negar.py │   ├── Virastar.py │   ├── Virastar.pyc │   ├── __init__.py │   ├── data │   │   ├── __init__.py │   │   └── untouchable.dat │   ├── gui.py │   ├── gui.pyc │   ├── i18n │   │   ├── fa_IR.qm │   │   └── fa_IR.ts │   └── negar.pro ├── setup.py ... 

and inside that my file Virastar.py need some data from data.untouchable.dat. it works fine until I install the project with this setup.py:

setup(     ...     include_package_data=True,     packages = find_packages() + ['negar'],     package_dir={'negar': 'negar'},     package_data={'negar': ['data/*.dat']},     entry_points={         'console_scripts': [             'negar = negar.Negar:main',         ],     },      ...   ) 

after that when I start my program and when it needs that data file it return this error:

IOError: [Errno 2] No such file or directory: 'data/untochable.dat' 

even in my egg-info sources I can't find any data file:

... negar/Negar.py negar/Virastar.py negar/__init__.py negar/gui.py negar/data/__init__.py 

have I missed something here?

Thank you all.

EDIT: Do I have to add any special thing in init.py?

and I have to add this: I used untouchable.dat just like this:

f = codecs.open('data/untouchable.dat', encoding="utf-8") 

Answer 1

I used data_files

data_files = [('', ['negar/data/untouchable.dat'])], 

Answer 2

The first problem is that I didn't import my data file into the package with MANIFEST.in file. I imported it like this:

include negar/data/*.dat 

After that my data file already imported with my package install. but because I had mistakes in open my data files, python couldn't find it. this question helped me to find the right way Python Access Data in Package Subdirectory and now I use something like this:

import os this_dir, this_filename = os.path.split(__file__) DATA_PATH = os.path.join(this_dir, "data", "data.txt") print open(DATA_PATH).read()
