The Gaussian Process Toolbox

Project description

# GPy

The Gaussian processes framework in Python.

* GPy [homepage](
* Tutorial [notebooks](
* User [mailing-list](
* Developer [documentation](
* Travis-CI [unit-tests](
* [![licence](](

## Updated Structure

We have pulled the core parameterization out of GPy. It is a package called [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 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]( and thus, we strongly recommend using
the [anaconda python distribution](
With anaconda you can install GPy by the following:

conda update scipy
pip install gpy

We've also had luck with [enthought]( 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
cd GPy
git checkout devel
python build_ext --inplace
nosetests GPy/testing

### Direct downloads

[![PyPI version](]( [![source](](

## 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 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 ~/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:

**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
