Updated Structure
-----------------

We have pulled the core parameterization out of GPy. It is a package
called `paramz <https://github.com/sods/paramz>`__ and is the pure
gradient based model optimization.

If you installed GPy with pip, just upgrade the package using:

::

    $ pip install --upgrade GPy

If you have the developmental version of GPy (using the develop or -e
option) just install the dependencies by running

::

    $ python setup.py develop

again, in the GPy installation folder.

A warning: This usually works, but sometimes ``distutils/setuptools``
opens a whole can of worms here, specially when compiled extensions are
involved. If that is the case, it is best to clean the repo and
reinstall.

Pronounciation:
~~~~~~~~~~~~~~~

We like to pronounce it 'g-pie'.

Getting started: installing with pip
------------------------------------

We are now requiring the newest version (0.16) of
`scipy <http://www.scipy.org/>`__ and thus, we strongly recommend using
the `anaconda python distribution <http://continuum.io/downloads>`__.
With anaconda you can install GPy by the following:

::

    conda update scipy
    pip install gpy

We've also had luck with `enthought <http://www.enthought.com>`__.
Install scipy 0.16 (or later) and then pip install GPy:

::

    pip install gpy

If you'd like to install from source, or want to contribute to the
project (i.e. by sending pull requests via github), read on.

Troubleshooting installation problems
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

If you're having trouble installing GPy via ``pip install GPy`` here is
a probable solution:

::

    git clone https://github.com/SheffieldML/GPy.git
    cd GPy
    git checkout devel
    python setup.py build_ext --inplace
    nosetests GPy/testing

Direct downloads
~~~~~~~~~~~~~~~~

|PyPI version| |source| |Windows| |MacOSX|

Running unit tests:
-------------------

Ensure nose is installed via pip:

::

    pip install nose

Run nosetests from the root directory of the repository:

::

    nosetests -v GPy/testing

or from within IPython

::

    import GPy; GPy.tests()

or using setuptools

::

    python setup.py test

Ubuntu hackers
--------------

    Note: Right now the Ubuntu package index does not include scipy
    0.16.0, and thus, cannot be used for GPy. We hope this gets fixed
    soon.

For the most part, the developers are using ubuntu. To install the
required packages:

::

    sudo apt-get install python-numpy python-scipy python-matplotlib

clone this git repository and add it to your path:

::

    git clone git@github.com:SheffieldML/GPy.git ~/SheffieldML
    echo 'PYTHONPATH=$PYTHONPATH:~/SheffieldML' >> ~/.bashrc

Compiling documentation:
------------------------

The documentation is stored in doc/ and is compiled with the Sphinx
Python documentation generator, and is written in the reStructuredText
format.

The Sphinx documentation is available here:
http://sphinx-doc.org/latest/contents.html

**Installing dependencies:**

To compile the documentation, first ensure that Sphinx is installed. On
Debian-based systems, this can be achieved as follows:

::

    sudo apt-get install python-pip
    sudo pip install sphinx

**Compiling documentation:**

The documentation can be compiled as follows:

::

    cd doc
    sphinx-apidoc -o source/ ../GPy/
    make html

The HTML files are then stored in doc/build/html
