Chapter 4: Graph Data Pipeline

(中文版)

DGL implements many commonly used graph datasets in dgl.data. They follow a standard pipeline defined in class dgl.data.DGLDataset. DGL highly recommends processing graph data into a dgl.data.DGLDataset subclass, as the pipeline provides simple and clean solution for loading, processing and saving graph data.

Roadmap

This chapter introduces how to create a custom DGL-Dataset. The following sections explain how the pipeline works, and shows how to implement each component of it.

• 4.1 DGLDataset class

• 4.2 Download raw data (optional)

• 4.3 Process data

• 4.4 Save and load data

• 4.5 Loading OGB datasets using ogb package

• 4.6 Loading data from CSV files
