[Website](https://www.dgl.ai) | [A Blitz Introduction to DGL](https://docs.dgl.ai/tutorials/blitz/index.html) | Documentation ([Latest](https://docs.dgl.ai/en/latest/) | [Stable](https://docs.dgl.ai)) | [Official Examples](examples/README.md) | [Discussion Forum](https://discuss.dgl.ai) | [Slack Channel](https://join.slack.com/t/deep-graph-library/shared_invite/zt-eb4ict1g-xcg3PhZAFAB8p6dtKuP6xQ)

DGL is an easy-to-use, high performance and scalable Python package for deep learning on graphs. DGL is framework agnostic, meaning if a deep graph model is a component of an end-to-end application, the rest of the logics can be implemented in any major frameworks, such as PyTorch, Apache MXNet or TensorFlow.

## Highlighted Features

### A GPU-ready graph library

DGL provides a powerful graph object that can reside on either CPU or GPU. It bundles structural data as well as features for a better control. We provide a variety of functions for computing with graph objects including efficient and customizable message passing primitives for Graph Neural Networks.

### Models, modules and benchmarks for GNN researchers

The field of graph deep learning is still rapidly evolving and many research ideas emerge by standing on the shoulders of giants. To ease the process, DGL collects a rich set of [example implementations](https://github.com/dmlc/dgl/tree/master/examples) of popular GNN models of a wide range of topics. Researchers can [search](https://www.dgl.ai/) for related models to innovate new ideas from or use them as baselines for experiments. Moreover, DGL provides many state-of-the-art [GNN layers and modules](https://docs.dgl.ai/api/python/nn.html) for users to build new model architectures. DGL is one of the preferred platforms for many standard graph deep learning benchmarks including [OGB](https://ogb.stanford.edu/) and [GNNBenchmarks](https://github.com/graphdeeplearning/benchmarking-gnns).

### Easy to learn and use

DGL provides a plenty of learning materials for all kinds of users from ML researcher to domain experts. The [Blitz Introduction to DGL](https://docs.dgl.ai/tutorials/blitz/index.html) is a 120-minute tour of the basics of graph machine learning. The [User Guide](https://docs.dgl.ai/guide/index.html) explains in more details the concepts of graphs as well as the training methodology. All of them include code snippets in DGL that are runnable and ready to be plugged into one’s own pipeline.

### Scalable and efficient

It is convenient to train models using DGL on large-scale graphs across multiple GPUs or multiple machines. DGL extensively optimizes the whole stack to reduce the overhead in communication, memory consumption and synchronization. As a result, DGL can easily scale to billion-sized graphs. See the [system performance note](https://docs.dgl.ai/performance.html) for the comparison with the other tools.

## Get Started

Users can install DGL from [pip and conda](https://www.dgl.ai/pages/start.html). Advanced users can follow the [instructions](https://docs.dgl.ai/install/index.html#install-from-source) to install from source.

For absolute beginners, start with [the Blitz Introduction to DGL](https://docs.dgl.ai/tutorials/blitz/index.html). It covers the basic concepts of common graph machine learning tasks and a step-by-step on building Graph Neural Networks (GNNs) to solve them.

For acquainted users who wish to learn more,

* Learn DGL by [example implementations](https://www.dgl.ai/) of popular GNN models.
* Read the [User Guide](https://docs.dgl.ai/guide/index.html) ([中文版链接](https://docs.dgl.ai/guide_cn/index.html)), which explains the concepts and usage of DGL in much more details.
* Go through the tutorials for advanced features like [stochastic training of GNNs](https://docs.dgl.ai/tutorials/large/index.html), training on [multi-GPU](https://docs.dgl.ai/tutorials/multi/index.html) or [multi-machine](https://docs.dgl.ai/tutorials/dist/index.html).
* [Study classical papers](https://docs.dgl.ai/tutorials/models/index.html) on graph machine learning alongside DGL.
* Search for the usage of a specific API in the [API reference manual](https://docs.dgl.ai/api/python/index.html), which organizes all DGL APIs by their namespace.

All the learning materials are available at our [documentation site](https://docs.dgl.ai/). If you are new to deep learning in general, 
check out the open source book [Dive into Deep Learning](https://d2l.ai/).
