Efficient Graph Deep Learning in TensorFlow with tf_geometric

We introduce tf_geometric1, an efficient and friendly library for graph deep learning, which is compatible with both TensorFlow 1.x and 2.x. It provides kernel libraries for building Graph Neural Networks (GNNs) as well as implementations of popular GNNs. The kernel libraries consist of infrastructures for building efficient GNNs, including graph data structures, graph map-reduce framework, graph mini-batch strategy, etc. These infrastructures enable tf_geometric to support single-graph computation, multi-graph computation, graph mini-batch, distributed training, etc.; therefore, tf_geometric can be used for a variety of graph deep learning tasks, such as node classification, link prediction, and graph classification. Based on the kernel libraries, tf_geometric implements a variety of popular GNN models. To facilitate the implementation of GNNs, tf_geometric also provides some other libraries for dataset management, graph sampling, etc. Different from existing popular GNN libraries, tf_geometric provides not only Object-Oriented Programming (OOP) APIs, but also Functional APIs, which enable tf_geometric to handle advanced tasks such as graph meta-learning. The APIs are friendly and suitable for both beginners and experts.
