Q<sup style="font-size: 0.5em;">&#9428;</sup>PyTorch is a Q-exponential process library implemented using PyTorch built on [GPyTorch](https://gpytorch.ai). Q<sup style="font-size: 0.5em;">&#9428;</sup>PyTorch is designed for creating scalable, flexible, and modular Q-exponential process models with ease.

Internally, Q<sup style="font-size: 0.5em;">&#9428;</sup>PyTorch differs from many existing approaches to QEP inference by performing most inference operations using numerical linear algebra techniques like preconditioned conjugate gradients.
Implementing a scalable QEP method is as simple as providing a matrix multiplication routine with the kernel matrix and its derivative via our [LinearOperator](https://github.com/cornellius-gp/linear_operator) interface,
or by composing many of our already existing `LinearOperators`.
This allows not only for easy implementation of popular scalable QEP techniques,
but often also for significantly improved utilization of GPU computing compared to solvers based on the Cholesky decomposition.

Q<sup style="font-size: 0.5em;">&#9428;</sup>PyTorch provides (1) significant GPU acceleration (through MVM based inference);
(2) state-of-the-art implementations of the latest algorithmic advances for scalability and flexibility ([SKI/KISS-GP](http://proceedings.mlr.press/v37/wilson15.pdf), [stochastic Lanczos expansions](https://arxiv.org/abs/1711.03481), [LOVE](https://arxiv.org/pdf/1803.06058.pdf), [SKIP](https://arxiv.org/pdf/1802.08903.pdf), [stochastic variational](https://arxiv.org/pdf/1611.00336.pdf) [deep kernel learning](http://proceedings.mlr.press/v51/wilson16.pdf), ...);
(3) easy integration with deep learning frameworks.


## Examples, Tutorials, and Documentation

## Installation

**Requirements**:
- Python >= 3.10
- PyTorch >= 2.2
- GPyTorch >= 1.13

Install Q<sup style="font-size: 0.5em;">&#9428;</sup>PyTorch using pip or conda:

```bash
pip install qpytorch
conda install qpytorch -c qpytorch
```

(To use packages globally but install Q<sup style="font-size: 0.5em;">&#9428;</sup>PyTorch as a user-only package, use `pip install --user` above.)

#### Latest (Unstable) Version

To upgrade to the latest (unstable) version, run

```bash
pip install --upgrade git+https://github.com/cornellius-gp/linear_operator.git
pip install --upgrade git+https://github.com/cornellius-gp/gpytorch.git
pip install --upgrade git+https://github.com/lanzithinking/qepytorch.git
```

#### Development version

If you are contributing a pull request, it is best to perform a manual installation:

```sh
git clone https://github.com/lanzithinking/qepytorch.git qpytorch
cd qpytorch
pip install -e .[dev,docs,examples,keops,pyro,test]  # keops and pyro are optional
```

<!--
#### ArchLinux Package
**Note**: Experimental AUR package. For most users, we recommend installation by conda or pip.
