DIG: Dive into Graphs is a turnkey library for graph deep learning research.
Why DIG?
The key difference with current graph deep learning libraries, such as PyTorch Geometric (PyG) and Deep Graph Library (DGL), is that, while PyG and DGL support basic graph deep learning operations, DIG provides a unified testbed for higher level, research-oriented graph deep learning tasks, such as graph generation, self-supervised learning, explainability, and 3D graphs.
If you are working or plan to work on research in graph deep learning, DIG enables you to develop your own methods within our extensible framework, and compare with current baseline methods using common datasets and evaluation metrics without extra efforts.
Overview
It includes unified implementations of data interfaces, common algorithms, and evaluation metrics for several advanced tasks. Our goal is to enable researchers to easily implement and benchmark algorithms. Currently, we consider the following research directions.
- Graph Generation:
dig.ggraph - Self-supervised Learning on Graphs:
dig.sslgraph - Explainability of Graph Neural Networks:
dig.xgraph - Deep Learning on 3D Graphs:
dig.threedgraph
Usage
Example: a few lines of code to run SphereNet on QM9 to incorporate 3D information of molecules.
from dig.threedgraph.dataset import QM93D
from dig.threedgraph.method import SphereNet
from dig.threedgraph.evaluation import ThreeDEvaluator
from dig.threedgraph.method import run
# Load the dataset and split
dataset = QM93D(root='dataset/')
target = 'U0'
dataset.data.y = dataset.data[target]
split_idx = dataset.get_idx_split(len(dataset.data.y), train_size=110000, valid_size=10000, seed=42)
train_dataset, valid_dataset, test_dataset = dataset[split_idx['train']], dataset[split_idx['valid']], dataset[split_idx['test']]
# Define model, loss, and evaluation
model = SphereNet(energy_and_force=False, cutoff=5.0, num_layers=4,
hidden_channels=128, out_channels=1, int_emb_size=64,
basis_emb_size_dist=8, basis_emb_size_angle=8, basis_emb_size_torsion=8, out_emb_channels=256,
num_spherical=3, num_radial=6, envelope_exponent=5,
num_before_skip=1, num_after_skip=2, num_output_layers=3)
loss_func = torch.nn.L1Loss()
evaluation = ThreeDEvaluator()
# Train and evaluate
run3d = run()
run3d.run(device, train_dataset, valid_dataset, test_dataset, model, loss_func, evaluation,
epochs=20, batch_size=32, vt_batch_size=32, lr=0.0005, lr_decay_factor=0.5, lr_decay_step_size=15)

Installation
Install from pip
The key dependencies of DIG: Dive into Graphs are PyTorch (>=1.6.0), PyTorch Geometric (>=1.6.0), and RDKit.
- Install PyTorch (>=1.6.0)
$ python -c "import torch; print(torch.__version__)"
>>> 1.6.0
- Install PyTorch Geometric (>=1.6.0)
$ python -c "import torch_geometric; print(torch_geometric.__version__)"
>>> 1.6.0
Note: Our library has not been tested on PyTorch Geometric >= 2.0.0, which is largely different with PyTorch Geometric 1.x.x. Hence, we recommend to install PyTorch Geometric with a version from 1.6.0 to 1.7.2.
- Install DIG: Dive into Graphs.
pip install dive-into-graphs
After installation, you can check the version. You have successfully installed DIG: Dive into Graphs if no error occurs.
$ python
>>> from dig.version import __version__
>>> print(__version__)
