Graph neural networks (GNNs) have attracted tremendous attention from the
graph learning community in recent years. It has been widely adopted in various
real-world applications from diverse domains, such as social networks and
biological graphs. The research and applications of graph deep learning present
new challenges, including the sparse nature of graph data, complicated training
of GNNs, and non-standard evaluation of graph tasks. To tackle the issues, we
present CogDL, a comprehensive library for graph deep learning that allows
researchers and practitioners to conduct experiments, compare methods, and
build applications with ease and efficiency. In CogDL, we propose a unified
design for the training and evaluation of GNN models for various graph tasks,
making it unique among existing graph learning libraries. By utilizing this
unified trainer, CogDL can optimize the GNN training loop with several training
techniques, such as mixed precision training. Moreover, we develop efficient
sparse operators for CogDL, enabling it to become the most competitive graph
library for efficiency. Another important CogDL feature is its focus on ease of
use with the aim of facilitating open and reproducible research of graph
learning. We leverage CogDL to report and maintain benchmark results on
fundamental graph tasks, which can be reproduced and directly used by the
community.
