GPyTorch is a Gaussian Process library, implemented using PyTorch. It is designed for creating flexible and modular Gaussian Process models with ease, so that you don't have to be an expert to use GPs.
This package is currently under development, and is likely to change. Some things you can do right now:
- Simple GP regression (example here)
- Simple GP classification (example here)
- Multitask GP regression (example here)
- Scalable GP regression using kernel interpolation (example here)
- Scalable GP classification using kernel interpolation (example here)
- Deep kernel learning (example here)
- And (more!)

The easiest way to install GPyTorch is by installing PyTorch >= 0.4.0
using the appropriate command from here, and then installing
GPyTorch using pip:
pip install git+https://github.com/cornellius-gp/gpytorch.git
To use packages globally but install GPyTorch as a user-only package, use pip install --user
above.
We also provide two conda environment files, environment.yml
and environment_cuda90.yml
. As an example, to install GPyTorch in a conda environment with cuda support, run:
git clone git+https://github.com/cornellius-gp/gpytorch.git
conda create -f gpytorch/environment_cuda.yml
source activate gpytorch
pip install gpytorch/
Still a work in progress. For now, please refer to the following example Jupyter notebooks.
To run the unit tests:
python -m unittest
By default, the random seeds are locked down for some of the tests. If you want to run the tests without locking down the seed, run
UNLOCK_SEED=true python -m unittest
Please lint the code with flake8
.
pip install flake8 # if not already installed
flake8
