Making a python package for PIP with some data_files - python

I'm doing a project with this layout:
project/
bin/
my_bin.py
CHANGES.txt
docs/
LICENSE.txt
README.txt
MANIFEST.in
setup.py
project/
__init__.py
some_thing.py
default_data.json
other_datas/
default/
other_default_datas.json
And the problem is that when I install this using pip, it puts the "default_data.json" and the "other_datas" folder not in the same place as the rest of the app.
How am I supposed to do to make them be in the same place?
They end up on "/home/user/.virtualenvs/proj-env/project"
instead of "/home/user/.virtualenvs/proj-env/lib/python2.6/site-packages/project"
In the setup.py I'm doing it like this:
inside_dir = 'project'
data_folder= os.path.join(inside_dir,'other_datas')
data_files = [(inside_dir, [os.path.join(inside_dir,'default_data.json')])]
for dirpath, dirnames, filenames in os.walk(data_folder):
data_files.append([dirpath, [os.path.join(dirpath, f) for f in filenames]])

From https://docs.python.org/3.4/distutils/setupscript.html#installing-additional-files:
If directory is a relative path, it is interpreted relative to the installation prefix (Python’s sys.prefix for pure-Python packages, sys.exec_prefix for packages that contain extension modules).
Each file name in files is interpreted relative to the setup.py script at the top of the package source distribution.
So the described behavior is simply how data_files work.
If you want to include the data files within your package you need to use package_data instead:
package_data={'project': ['default_data.json', 'other_datas/default/*.json']}

Take a look at this package https://pypi.python.org/pypi/datafolder. It makes it easy to install and use (data files: *.conf, *.ini *.db, ...) by your package and by the user.

Change your MANIFEST.in to include those .json.
It is probably gonna work:
recursive-include project/ *.json

How to configure python setuptools to install modules in the root directory as a single package?

I am using setuptools to create a python package. This is the directory structure:
mypackage
.git
__init__.py
pyproject.toml
setup.cfg
module1.py
module2.py
I have this structured in a flat hierarchy so I can clone this repository/copy this directory into a parent project/repository and directly write from mypackage import something, instead of having to pip install or play around with PYTHONPATH.
What do I specify in the setup.cfg file, such that this is installed as a single package, given the file structure?
# setup.cfg
[options]
package_dir = # What is here?
I tried out the custom discovery options in setuptools, which seems to work. I have to manually specify the root directory for packages. However setuptools fails when it finds multiple top-level modules/packages. So I have to use the find option to explicitly include discovered modules into a single package.
[options]
# Use the find function to find modules/packages
packages = find:
# The root directory is the current directory, relative to setup.cfg
packages_dir =
.
[options.packages.find]
# Options for the find command. Include is implicitly looking for all .py files,
# where the directory is "."
where = .

How to exclude a single file from package with setuptools and setup.py

I am working on blowdrycss. The repository is here.
I want the settings file for blowdrycss_settings.py to be excluded from the final package on pypi. The intention is to dynamically build a custom settings file that will be placed in the users virtualenv / project folder.
In setup.py, I have the following:
packages=find_packages(exclude=['blowdrycss_settings.py', ]),
I also tried exclude_package_data:
exclude_package_data={
'': ['blowdrycss_settings.py'],
'': ['blowdrycss/blowdrycss_settings.py'],
'blowdrycss': ['blowdrycss_settings.py'],
},
I then run python setup.py sdist bdist.
However, when I look in the build folder I still see blowdrycss_settings.py:
- build
- lib
- blowdrycss_settings.py
It seems like it should be simple to just exclude a file.
How do I exclude blowdrycss_settings.py from the distributed package?
Imagine you have a project
root
├── setup.py
└── spam
├── __init__.py
├── bacon.py
└── eggs.py
and you want to exclude spam/eggs.py from packaging:
import fnmatch
from setuptools import find_packages, setup
from setuptools.command.build_py import build_py as build_py_orig
excluded = ['spam/eggs.py']
class build_py(build_py_orig):
def find_package_modules(self, package, package_dir):
modules = super().find_package_modules(package, package_dir)
return [
(pkg, mod, file)
for (pkg, mod, file) in modules
if not any(fnmatch.fnmatchcase(file, pat=pattern) for pattern in excluded)
]
setup(
packages=find_packages(),
cmdclass={'build_py': build_py}
)
Globs and multiple entries in excluded list will work too because it is consumed by fnmatch, so you can e.g. declare
excluded = [
'modules_in_directory/*.py',
'modules_in_subtree/**/*.py',
'path/to/other/module.py'
]
etc.
This recipe is based on my other answer to the question setup.py exclude some python files from bdist
. The difference is that this recipe excludes modules based on file globs, while the other one excludes modules based on qualnames, for example
excluded = ['spam.*', '*.settings']
will exclude all submodules of spam package and all modules named settings in every package and subpackage etc.
Here is my solution.
Underneath of blowdrycss, I created a new module called settings so the directory structure now looks like this:
blowdrycss
blowdrycss
settings
blowdrycss_settings.py
Based on this reference, inside of setup.py I have the following:
packages=find_packages(exclude=['*.settings', ]),
To build the distribution:
Delete the build, dist, and .egg-info folders.
Run python setup.py sdist bdist
In retrospect, it is good that I was unable to do what I was originally attempting. The new structure feels cleaner and is more modular.
The easiest way to remove a single, or at least a few specific files, from a package with setuptools is just to use the MANIFEST.in. For example, in a package you can exclude all files name foo.py by simply specifying global-exclude foo.py. There's no need for setuptools hacking or changing the structure of your package if you just use the MANIFEST.in method.
See the dedicated PyPA article on using MANIFEST.in for more commands you can use.

jinja2 and distutils - how can I make distutils install template together with modules [duplicate]

How do I make setup.py include a file that isn't part of the code? (Specifically, it's a license file, but it could be any other thing.)
I want to be able to control the location of the file. In the original source folder, the file is in the root of the package. (i.e. on the same level as the topmost __init__.py.) I want it to stay exactly there when the package is installed, regardless of operating system. How do I do that?
Probably the best way to do this is to use the setuptools package_data directive. This does mean using setuptools (or distribute) instead of distutils, but this is a very seamless "upgrade".
Here's a full (but untested) example:
from setuptools import setup, find_packages
setup(
name='your_project_name',
version='0.1',
description='A description.',
packages=find_packages(exclude=['ez_setup', 'tests', 'tests.*']),
package_data={'': ['license.txt']},
include_package_data=True,
install_requires=[],
)
Note the specific lines that are critical here:
package_data={'': ['license.txt']},
include_package_data=True,
package_data is a dict of package names (empty = all packages) to a list of patterns (can include globs). For example, if you want to only specify files within your package, you can do that too:
package_data={'yourpackage': ['*.txt', 'path/to/resources/*.txt']}
The solution here is definitely not to rename your non-py files with a .py extension.
See Ian Bicking's presentation for more info.
UPDATE: Another [Better] Approach
Another approach that works well if you just want to control the contents of the source distribution (sdist) and have files outside of the package (e.g. top-level directory) is to add a MANIFEST.in file. See the Python documentation for the format of this file.
Since writing this response, I have found that using MANIFEST.in is typically a less frustrating approach to just make sure your source distribution (tar.gz) has the files you need.
For example, if you wanted to include the requirements.txt from top-level, recursively include the top-level "data" directory:
include requirements.txt
recursive-include data *
Nevertheless, in order for these files to be copied at install time to the package’s folder inside site-packages, you’ll need to supply include_package_data=True to the setup() function. See Adding Non-Code Files for more information.
To accomplish what you're describing will take two steps...
The file needs to be added to the source tarball
setup.py needs to be modified to install the data file to the source path
Step 1: To add the file to the source tarball, include it in the MANIFEST
Create a MANIFEST template in the folder that contains setup.py
The MANIFEST is basically a text file with a list of all the files that will be included in the source tarball.
Here's what the MANIFEST for my project look like:
CHANGELOG.txt
INSTALL.txt
LICENSE.txt
pypreprocessor.py
README.txt
setup.py
test.py
TODO.txt
Note: While sdist does add some files automatically, I prefer to explicitly specify them to be sure instead of predicting what it does and doesn't.
Step 2: To install the data file to the source folder, modify setup.py
Since you're looking to add a data file (LICENSE.txt) to the source install folder you need to modify the data install path to match the source install path. This is necessary because, by default, data files are installed to a different location than source files.
To modify the data install dir to match the source install dir...
Pull the install dir info from distutils with:
from distutils.command.install import INSTALL_SCHEMES
Modify the data install dir to match the source install dir:
for scheme in INSTALL_SCHEMES.values():
scheme['data'] = scheme['purelib']
And, add the data file and location to setup():
data_files=[('', ['LICENSE.txt'])]
Note: The steps above should accomplish exactly what you described in a standard manner without requiring any extension libraries.
It is 2019, and here is what is working -
despite advice here and there, what I found on the internet halfway documented is using setuptools_scm, passed as options to setuptools.setup. This will include any data files that are versioned on your VCS, be it git or any other, to the wheel package, and will make "pip install" from the git repository to bring those files along.
So, I just added these two lines to the setup call on "setup.py". No extra installs or import required:
setup_requires=['setuptools_scm'],
include_package_data=True,
No need to manually list package_data, or in a MANIFEST.in file - if it is versioned, it is included in the package. The docs on "setuptools_scm" put emphasis on creating a version number from the commit position, and disregard the really important part of adding the data files. (I can't care less if my intermediate wheel file is named "*0.2.2.dev45+g3495a1f" or will use the hardcoded version number "0.3.0dev0" I've typed in - but leaving crucial files for the program to work behind is somewhat important)
create MANIFEST.in in the project root with recursive-include to the required directory or include with the file name.
include LICENSE
include README.rst
recursive-include package/static *
recursive-include package/templates *
documentation can be found here
Step 1: create a MANIFEST.in file in the same folder with setup.py
Step 2: include the relative path to the files you want to add in MANIFEST.in
include README.rst
include docs/*.txt
include funniest/data.json
Step 3: set include_package_data=True in the setup() function to copy these files to site-package
Reference is here.
I wanted to post a comment to one of the questions but I don't enough reputation to do that >.>
Here's what worked for me (came up with it after referring the docs):
package_data={
'mypkg': ['../*.txt']
},
include_package_data: False
The last line was, strangely enough, also crucial for me (you can also omit this keyword argument - it works the same).
What this does is it copies all text files in your top-level or root directory (one level up from the package mypkg you want to distribute).
None of the above really worked for me. What saved me was this answer.
Apparently, in order for these data files to be extracted during installation, I had to do a couple of things:
Like already mentioned - Add a MANIFEST.in to the project and specify the folder/files you want to be included. In my case: recursive-include folder_with_extra_stuff *
Again, like already mentioned - Add include_package_data=True to your setup.py. This is crucial, because without it only the files that match *.py will be brought.
This is what was missing! - Add an empty __init__.py to your data folder. For me I had to add this file to my folder-with-extra-stuff.
Extra - Not sure if this is a requirement, but with my own python modules I saw that they're zipped inside the .egg file in site-packages. So I had to add zip_safe=False to my setup.py file.
Final Directory Structure
my-app/
├─ app/
│ ├─ __init__.py
│ ├─ __main__.py
├─ folder-with-extra-stuff/
│ ├─ __init__.py
│ ├─ data_file.json
├─ setup.py
├─ MANIFEST.in
This works in 2020!
As others said create "MANIFEST.in" where your setup.py is located.
Next in manifest include/exclude all the necessary things. Be careful here regarding the syntax.
Ex: lets say we have template folder to be included in the source package.
in manifest file do this :
recursive-include template *
Make sure you leave space between dir-name and pattern for files/dirs like above.
Dont do like this like we do in .gitignore
recursive-include template/* [this won't work]
Other option is to use include. There are bunch of options. Look up here at their docs for Manifest.in
And the final important step, include this param in your setup.py and you are good to go!
setup(
...
include_package_data=True,
......
)
Hope that helps! Happy Coding!
In setup.py under setup( :
setup(
name = 'foo library'
...
package_data={
'foolibrary.folderA': ['*'], # All files from folder A
'foolibrary.folderB': ['*.txt'] #All text files from folder B
},
Here is a simpler answer that worked for me.
First, per a Python Dev's comment above, setuptools is not required:
package_data is also available to pure distutils setup scripts
since 2.3. – Éric Araujo
That's great because putting a setuptools requirement on your package means you will have to install it also. In short:
from distutils.core import setup
setup(
# ...snip...
packages = ['pkgname'],
package_data = {'pkgname': ['license.txt']},
)
I just wanted to follow up on something I found working with Python 2.7 on Centos 6. Adding the package_data or data_files as mentioned above did not work for me. I added a MANIFEST.IN with the files I wanted which put the non-python files into the tarball, but did not install them on the target machine via RPM.
In the end, I was able to get the files into my solution using the "options" in the setup/setuptools. The option files let you modify various sections of the spec file from setup.py. As follows.
from setuptools import setup
setup(
name='theProjectName',
version='1',
packages=['thePackage'],
url='',
license='',
author='me',
author_email='me#email.com',
description='',
options={'bdist_rpm': {'install_script': 'filewithinstallcommands'}},
)
file - MANIFEST.in:
include license.txt
file - filewithinstallcommands:
mkdir -p $RPM_BUILD_ROOT/pathtoinstall/
#this line installs your python files
python setup.py install -O1 --root=$RPM_BUILD_ROOT --record=INSTALLED_FILES
#install license.txt into /pathtoinstall folder
install -m 700 license.txt $RPM_BUILD_ROOT/pathtoinstall/
echo /pathtoinstall/license.txt >> INSTALLED_FILES
None of the answers worked for me because my files were at the top level, outside the package. I used a custom build command instead.
import os
import setuptools
from setuptools.command.build_py import build_py
from shutil import copyfile
HERE = os.path.abspath(os.path.dirname(__file__))
NAME = "thepackage"
class BuildCommand(build_py):
def run(self):
build_py.run(self)
if not self.dry_run:
target_dir = os.path.join(self.build_lib, NAME)
for fn in ["VERSION", "LICENSE.txt"]:
copyfile(os.path.join(HERE, fn), os.path.join(target_dir,fn))
setuptools.setup(
name=NAME,
cmdclass={"build_py": BuildCommand},
description=DESCRIPTION,
...
)
For non-python files to be included in an installation, they must be within one of the installed package directories. If you specify non-python files outside of your package directories in MANIFEST.in, they will be included in your distribution, but they will not be installed. The "documented" ways of installing arbitrary files outside of your package directories do not work reliably (as everyone has noticed by now).
The above answer from Julian Mann copies the files to your package directory in the build directory, so it does work, but not if you are installing in editable/develop mode (pip install -e or python setup.py develop). Based on this answer to a related question (and Julian's answer), below is an example that copies files to your installed package location either way after all the other install/develop tasks are done. The assumption here is that files file1 and file2 in your root-level data directory will be copied to your installed package directory (my_package), and that they will be accessible from python modules in your package using os.path.join(os.path.dirname(__file__), 'file1'), etc.
Remember to also do the MANIFEST.in stuff described above so that these files are also included in your distribution. Why setuptools would include files in your distribution and then silently never install them, is beyond my ken. Though installing them outside of your package directory is probably even more dubious.
import os
from setuptools import setup
from setuptools.command.develop import develop
from setuptools.command.install import install
from shutil import copyfile
HERE = os.path.abspath(os.path.dirname(__file__))
NAME = 'my_package'
def copy_files (target_path):
source_path = os.path.join(HERE, 'data')
for fn in ["file1", "file2"]:
copyfile(os.path.join(source_path, fn), os.path.join(target_path,fn))
class PostDevelopCommand(develop):
"""Post-installation for development mode."""
def run(self):
develop.run(self)
copy_files (os.path.abspath(NAME))
class PostInstallCommand(install):
"""Post-installation for installation mode."""
def run(self):
install.run(self)
copy_files (os.path.abspath(os.path.join(self.install_lib, NAME)))
setup(
name=NAME,
cmdclass={
'develop': PostDevelopCommand,
'install': PostInstallCommand,
},
version='0.1.0',
packages=[NAME],
include_package_data=True,
setup_requires=['setuptools_scm'],
)
Figured out a workaround: I renamed my lgpl2.1_license.txt to lgpl2.1_license.txt.py, and put some triple quotes around the text. Now I don't need to use the data_files option nor to specify any absolute paths. Making it a Python module is ugly, I know, but I consider it less ugly than specifying absolute paths.

How can I get my setup.py to use a relative path to my files?

I'm trying to build a Python distribution with distutils. Unfortunately, my directory structure looks like this:
/code
/mypackage
__init__.py
file1.py
file2.py
/subpackage
__init__.py
/build
setup.py
Here's my setup.py file:
from distutils.core import setup
setup(
name = 'MyPackage',
description = 'This is my package',
packages = ['mypackage', 'mypackage.subpackage'],
package_dir = { 'mypackage' : '../mypackage' },
version = '1',
url = 'http://www.mypackage.org/',
author = 'Me',
author_email = 'me#here.com',
)
When I run python setup.py sdist it correctly generates the manifest file, but doesn't include my source files in the distribution. Apparently, it creates a directory to contain the source files (i.e. mypackage1) then copies each of the source files to mypackage1/../mypackage which puts them outside of the distribution.
How can I correct this, without forcing my directory structure to conform to what distutils expects?
What directory structure do you want inside of the distribution archive file? The same as your existing structure?
You could package everything one directory higher (code in your example) with this modified setup.py:
from distutils.core import setup
setup(
name = 'MyPackage',
description = 'This is my package',
packages = ['mypackage', 'mypackage.subpackage'],
version = '1',
url = 'http://www.mypackage.org/',
author = 'Me',
author_email = 'me#here.com',
script_name = './build/setup.py',
data_files = ['./build/setup.py']
)
You'd run this (in the code directory):
python build/setup.py sdist
Or, if you want to keep dist inside of build:
python build/setup.py sdist --dist-dir build/dist
I like the directory structure you're trying for. I've never thought setup.py was special enough to warrant being in the root code folder. But like it or not, I think that's where users of your distribution will expect it to be. So it's no surprise that you have to trick distutils to do something else. The data_files parameter is a hack to get your setup.py into the distribution in the same place you've located it.
Have it change to the parent directory first, perhaps?
import os
os.chdir(os.pardir)
from distutils.core import setup
etc.
Or if you might be running it from anywhere (this is overkill, but...):
import os.path
my_path = os.path.abspath(__file__)
os.chdir(os.normpath(os.path.join(my_path, os.pardir)))
etc. Not sure this works, but should be easy to try.
Run setup.py from the root folder of the project
In your case, place setup.py in code/
code/ should also include:
LICENSE.txt
README.txt
INSTALL.txt
TODO.txt
CHANGELOG.txt
The when you run "setup.py sdist' it should auto-gen a MANIFEST including:
- any files specified in py_modules and/or packages
- setup.py
- README.txt
To add more files just hand-edit the MANIFEST file to include whatever other files your project needs.
For a somewhat decent explanation of this read this.
To see a working example checkout my project.
Note: I don't put the MANIFEST under version control so you won't find it there.
A sorta lame workaround but I'd probably just use a Makefile that rsynced ./mypackage to ./build/mypackage and then use the usual distutils syntax from inside ./build. Fact is, distutils expects to unpack setup.py into the root of the sdist and have code under there, so you're going to have a devil of time convincing it to do otherwise.
You can always nuke the copy when you make clean so you don't have to mess up your vcs.
Also a lame workaround, but a junction/link of the package directory inside of the build project should work.

Packaging resources with setuptools/distribute

I'm developing an Python egg that has several .txt dependencies (they're templates used to generate files by the egg itself), and I'm struggling to get those dependencies copied to site-packages during setup.py install. According to the distribute documentation...
Filesystem of my package:
setup.py
package
|--- __init__.py
|--- main.py
|--- binary (calls main.py with pkg_resources.load_entry_point)
|--- templates
|--file1.txt
|--file2.txt
In setup.py:
setup(
[...]
eager_resources = ['templates/file1.txt', 'templates/file2.txt']
)
Within my package:
from pkg_resources import resource_string
tpl = resource_string(__name__, 'templates/file1.txt')
...this combination of configuration and filesystem should result in file1.txt and file2.txt being available through pkg_resources.resource_string. Unfortunately, they're not being copied to site-packages during setup.py install. What am I missing?
Thanks!
The information can be found in the setuptools documentation for including package data: https://setuptools.readthedocs.io/en/latest/setuptools.html#including-data-files
Basically, you just need to set include_package_data=True in your setup.py file. If you are using subversion or CVS, all versioned files will be included. If not, you can specify which files to include with a MANIFEST.in file.
I believe distribute supports this as well.
You can then access the files as you would without them being packaged. i.e. in main.py you could have:
import os.path
f = open(os.path.join(os.path.dirname(__file__),'templates','file1.txt'))
print f.read()
f.close()
and this would work in the packaged version as well. One caveat is that you will have to also set zip_safe = False in setup.py so that all the files are unzipped during installation.
