algebraixlib is a library that provides constructs and facilities to harness the fundamentals of data algebra. Data algebra consists of mathematical constructs that can represent all data, no matter how it is structured, and the operations on that data. With this, all the advantages of a mathematically rigorous modeling can be unleashed. See also A Beginner's Introduction to Data Algebra.

1. Make sure you have the required versions of Python and Jupyter Notebook installed (see Requirements below).
2. Install the algebraixlib library (see How to Install below).
3. Download the examples from our GitHub repository.
4. Try the Hello_World.ipynb example first.

(Alternatively, you can also look at a static version of the notebooks in nbviewer; see the README file in our examples directory for direct links. For this you don't need to install or download anything. You can also start with the simpler hello_world.py. However, you'll lose out on some math and need to read up on it in our documentation at Read the Docs. )

• Find documentation at Read the Docs.
• Find the pip installer on PyPI.
• Find the source code, the bugtracker and contribute on GitHub.
• Find tutorials and example code in the examples directory on GitHub.
• Post questions about algebraixlib on Stack Overflow using the tag [algebraixlib].
• Post questions about the mathematics of data algebra on math.stackexchange using the tag [data-algebra].
• Contact us by email.

See also our GitHub project page. In addition, there is a book about data algebra.

• Python: Tested with 3.6.1. Likely to run with Python 3.6.x and later. It may run with earlier Python 3 versions, but you may run into issues. Does not run with any version of Python before Python 3.
  • For installing and using multiple versions of Python on the same machine, see Official multiple python versions on the same machine? (Stack Overflow), How to install both Python 2.x and Python 3.x in Windows 7 (Stack Overflow) and A Python Launcher For Windows (Python Insider).
• Jupyter Notebook: Tested with Jupyter 5.2 (used in the Jupyter notebook tutorials and examples).
  • See Jupyter Installation for instructions how to install the Jupyter notebook (pip install jupyter).
  • If you don't want Jupyter in your system environment, you can install it into a virtual environment (see Creation of virtual environments).

If you already have Python installed and are familiar with installing packages, you can install algebraixlib with pip:

> pip install algebraixlib

Additional user permissions may be necessary to complete the installation. In such a situation, other options include installing the package for a single user (in the user's home directory):

> pip install algebraixlib --user <username> 

or in a virtual environment (see Creation of virtual environments).

You can also manually download algebraixlib from GitHub or PyPI. To install from a download, unpack it and run the following command from the top-level source directory (the directory that contains the file setup.py):

> python setup.py install

(The same considerations about permissions apply.)

The unit tests require the following libraries to be installed:

• nose
• coverage

To execute the unit tests, download the file runtests.py and the directory test into any location on your system, then run runtests.py:

> mkdir algebraixlib-test
> cd algebraixlib-test
> svn export https://github.com/AlgebraixData/algebraixlib/trunk/runtests.py
> svn export https://github.com/AlgebraixData/algebraixlib/trunk/test
> python runtests.py

The documentation build requires the following libraries be installed:

• Sphinx (1.3.2 or later)

To run a documentation build, you need a local working copy of our complete GitHub repository. Then run build.py in the directory docs:

> mkdir algebraixlib
> cd algebraixlib
> svn export https://github.com/AlgebraixData/algebraixlib/trunk
> cd trunk/docs
> python build.py
