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.

Using DGL

A data scientist may want to apply a pre-trained model to your data right away. For this you can use DGL's Application packages, formally Model Zoo. Application packages are developed for domain applications, as is the case for DGL-LifeScience. We will soon add model zoo for knowledge graph embedding learning and recommender systems. Here's how you will use a pretrained model: ```python from import Tox21 from dgllife.model import loadpretrained from dgllife.utils import smilesto_bigraph, CanonicalAtomFeaturizer

dataset = Tox21(smilestobigraph, CanonicalAtomFeaturizer()) model = loadpretrained('GCNTox21') # Pretrained model loaded model.eval()

smiles, g, label, mask = dataset[0] feats = g.ndata.pop('h') labelpred = model(g, feats) print(smiles) # CCOc1ccc2nc(S(N)(=O)=O)sc2c1 print(labelpred[:, mask != 0]) # Mask non-existing labels

tensor([[ 1.4190, -0.1820, 1.2974, 1.4416, 0.6914,

2.0957, 0.5919, 0.7715, 1.7273, 0.2070]])

**Further reading**: DGL is released as a managed service on AWS SageMaker, see the medium posts for an easy trip to DGL on SageMaker([part1]( and [part2](

Researchers can start from the growing list of models implemented in DGL. Developing new models does not mean that you have to start from scratch. Instead, you can reuse many pre-built modules. Here is how to get a standard two-layer graph convolutional model with a pre-built GraphConv module:

```python from dgl.nn.pytorch import GraphConv import torch.nn.functional as F

build a two-layer GCN with ReLU as the activation in between

class GCN(nn.Module): def init(self, in_feats, h_feats, num_classes): super(GCN, self).init() self.gcn_layer1 = GraphConv(in_feats, h_feats) self.gcn_layer2 = GraphConv(h_feats, num_classes)

def forward(self, graph, inputs):
    h = self.gcn_layer1(graph, inputs)
    h = F.relu(h)
    h = self.gcn_layer2(graph, h)
    return h

Next level down, you may want to innovate your own module. DGL offers a succinct message-passing interface (see tutorial here). Here is how Graph Attention Network (GAT) is implemented (complete codes). Of course, you can also find GAT as a module GATConv: ```python import torch.nn as nn import torch.nn.functional as F

Define a GAT layer

class GATLayer(nn.Module): def init(self, infeats, outfeats): super(GATLayer, self).init() self.linearfunc = nn.Linear(infeats, outfeats, bias=False) self.attentionfunc = nn.Linear(2 * out_feats, 1, bias=False)

def edge_attention(self, edges):
    concat_z =[edges.src['z'], edges.dst['z']], dim=1)
    src_e = self.attention_func(concat_z)
    src_e = F.leaky_relu(src_e)
    return {'e': src_e}

def message_func(self, edges): return {'z': edges.src['z'], 'e'['e']}

def reduce_func(self, nodes): a = F.softmax(nodes.mailbox['e'], dim=1) h = torch.sum(a * nodes.mailbox['z'], dim=1) return {'h': h}

def forward(self, graph, h): z = self.linear_func(h) graph.ndata['z'] = z graph.apply_edges(self.edge_attention) graph.update_all(self.message_func, self.reduce_func) return graph.ndata.pop('h')

## Performance and Scalability

Microbenchmark on speed and memory usage: While leaving tensor and autograd functions to backend frameworks (e.g. PyTorch, MXNet, and TensorFlow), DGL aggressively optimizes storage and computation with its own kernels. Here's a comparison to another popular package -- PyTorch Geometric (PyG). The short story is that raw speed is similar, but DGL has much better memory management.

PPI GAT 0.398 n/a 0.752

High memory utilization allows DGL to push the limit of single-GPU performance, as seen in below images. | | | | -------- | -------- |

Scalability: DGL has fully leveraged multiple GPUs in both one machine and clusters for increasing training speed, and has better performance than alternatives, as seen in below images.
