Installing with pip
-------------------
The simplest way to install GPy is using pip.
pip install gpy
The simplest way to install GPy is using pip. ubuntu users can do:
sudo apt-get install python-pip
pip install gpy
If you'd like to install from source, or want to contribute to the project (e.g. by sending pull requests via github), read on.
Ubuntu
------
For the most part, the developers are using ubuntu. To install the required packages:
sudo apt-get install python-numpy python-scipy python-matplotlib
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 \<destination\>
echo "PYTHONPATH=$PYTHONPATH:\<detination\> > ~/.bashrc
git clone git@github.com:SheffieldML/GPy.git ~/SheffieldML
echo 'PYTHONPATH=$PYTHONPATH:~/SheffieldML' >> ~/.bashrc
Windows
-------
On windows, we recommend the ![anaconda python distribution](http://continuum.io/downloads). We've also had luck with ![enthought](http://www.enthought.com). git clone or unzip the source to a suitable directory, and add a PYTHONPATH environement variable.

On windows 7 (and possibly earlier versions) there's a bug in scipy version 0.13 which tries to write very long filenames. Reverting to scipy 0.12 seems to do the trick:
conda install scipy=0.12
