        ============================================
        AstroML: Machine Learning code for Astronomy
        ============================================
        
        AstroML is a Python module for machine learning and data mining
        built on numpy, scipy, scikit-learn, and matplotlib,
        and distributed under the 3-Clause BSD license.
        It contains a growing library of statistical and machine learning
        routines for analyzing astronomical data in python, loaders for several open
        astronomical datasets, and a large suite of examples of analyzing and
        visualizing astronomical datasets.
        
        This project was started in 2012 by Jake VanderPlas to accompany the book
        *Statistics, Data Mining, and Machine Learning in Astronomy* by
        Zeljko Ivezic, Andrew Connolly, Jacob VanderPlas, and Alex Gray.
        
        Core and Addons
        ===============
        The project is split into two components.  The core ``astroML`` library is
        written in python only, and is designed to be very easy to install for
        any users, even those who don't have a working C or fortran compiler.
        A companion library, ``astroML_addons``, can be optionally installed for
        increased performance on certain algorithms.  Every algorithm
        in ``astroML_addons`` has a pure python counterpart in the
        core ``astroML`` implementation, but the ``astroML_addons`` library
        contains faster and more efficient implementations in compiled code.
        Furthermore, if ``astroML_addons`` is installed on your system, the core
        ``astroML`` library will import and use the faster routines by default.
        
        The reason for this split is the ease of use for newcomers to Python.  If the
        prerequisites are already installed on your system, the core ``astroML``
        library can be installed and used on any system with little trouble.  The
        ``astroML_addons`` library requires a C compiler, but is also designed to be
        easy to install for more advanced users.  See further discussion in
        "Development", below.

        Installation
        ============
        
        This package uses distutils, which is the default way of installing python
        modules.  **Before installation, make sure your system meets the prerequisites
        listed in Dependencies, listed below.**
        
        Core
        ----
        To install the core ``astroML`` package in your home directory, use::
        
          pip install astroML
        
        The core package is pure python, so installation should be straightforward
        on most systems.  To install from source, use::
        
          python setup.py install
        
        You can specify an arbitrary directory for installation using::
        
          python setup.py install --prefix='/some/path'
        
        To install system-wide on Linux/Unix systems::
        
          python setup.py build
          sudo python setup.py install
        
        Addons
        ------
        The ``astroML_addons`` package requires a working C/C++ compiler for
        installation.  It can be installed using::
        
          pip install astroML_addons
        
        To install from source, refer to http://github.com/astroML/astroML_addons
        
        
        Dependencies
        ============
        There are three levels of dependencies in astroML.  *Core* dependencies are
        required for the core ``astroML`` package.  *Add-on* dependencies are required
        for the performance ``astroML_addons``.  *Optional* dependencies are required
        to run some (but not all) of the example scripts.  Individual example scripts
        will list their optional dependencies at the top of the file.
        
        Core Dependencies
        -----------------
        The core ``astroML`` package requires the following:
        
        - Python_ version 2.6.x - 2.7.x
          (astroML does not yet support python 3.x)
        - Numpy_ >= 1.4
        - Scipy_ >= 0.7
        - Scikit-learn_ >= 0.10
        - Matplotlib_ >= 0.99
        - AstroPy_ > 0.2.5
          AstroPy is required to read Flexible Image Transport
          System (FITS) files, which are used by several datasets.
          
        This configuration matches the Ubuntu 10.04 LTS release from April 2010,
        with the addition of scikit-learn.
        
        To run unit tests, you will also need nose >= 0.10
        
        Add-on Dependencies
        -------------------
        The fast code in ``astroML_addons`` requires a working C/C++ compiler.
        
        Optional Dependencies
        ---------------------
        Several of the example scripts require specialized or upgraded packages.
        These requirements are listed at the top of the particular scripts
        
        - Scipy_ version 0.11 added a sparse graph submodule.
          The minimum spanning tree example requires scipy >= 0.11
        
        - PyMC_ provides a nice interface for Markov-Chain Monte Carlo. Several astroML
          examples use pyMC for exploration of high-dimensional spaces. The examples
          were written with pymc version 2.2
        
        - HEALPy_ provides an interface to
          the HEALPix pixelization scheme, as well as fast spherical harmonic
          transforms.
        
        Development
        ===========
        This package is designed to be a repository for well-written astronomy code,
        and submissions of new routines are encouraged.  After installing the
        version-control system Git_, you can check out
        the latest sources from GitHub_ using::
        
          git clone git://github.com/astroML/astroML.git
        
        or if you have write privileges::
        
          git clone git@github.com:astroML/astroML.git
        
        Contribution
        ------------
        We strongly encourage contributions of useful astronomy-related code:
        for `astroML` to be a relevant tool for the python/astronomy community,
        it will need to grow with the field of research.  There are a few
        guidelines for contribution:
        
        General
        ~~~~~~~
        Any contribution should be done through the github pull request system (for
        more information, see the
        `help page <https://help.github.com/articles/using-pull-requests>`_
        Code submitted to ``astroML`` should conform to a BSD-style license,
        and follow the `PEP8 style guide <http://www.python.org/dev/peps/pep-0008/>`_.
        
        Documentation and Examples
        ~~~~~~~~~~~~~~~~~~~~~~~~~~
        All submitted code should be documented following the
        `Numpy Documentation Guide`_.  This is a unified documentation style used
        by many packages in the scipy universe.
        
        In addition, it is highly recommended to create example scripts that show the
        usefulness of the method on an astronomical dataset (preferably making use
        of the loaders in ``astroML.datasets``).  These example scripts are in the
        ``examples`` subdirectory of the main source repository.
        
        Add-on code
        ~~~~~~~~~~~
        We made the decision early-on to separate the core routines from
        high-performance compiled routines.
        This is to make sure that installation of the core
        package is as straightforward as possible (i.e. not requiring a C compiler).
        
        Contributions of efficient compiled code to ``astroML_addons`` is encouraged:
        the availability of efficient implementations of common algorithms in python
        is one of the strongest features of the python universe.  The preferred
        method of wrapping compiled libraries is to use
        `cython <http://www.cython.org>`_; other options (weave, SWIG, etc.) are
        harder to build and maintain.
        
        Currently, the policy is that any efficient algorithm included in
        ``astroML_addons`` should have a duplicate python-only implementation in
        ``astroML``, with code that selects the faster routine if it's available.
        (For an example of how this works, see the definition of the ``lomb_scargle``
        function in ``astroML/periodogram.py``).
        This policy exists for two reasons:
        
         1. it allows novice users to have all the functionality of ``astroML`` without
            requiring the headache of complicated installation steps.
         2. it serves a didactic purpose: python-only implementations are often easier
            to read and understand than equivalent implementations in C or cython.
         3. it enforces the good coding practice of avoiding premature optimization.
            First make sure the code works (i.e. write it in simple python).  Then
            create an optimized version in the addons.
        
        If this policy proves especially burdensome in the future, it may be revisited.
