The `ogbg-molpcba` dataset is a small-scale dataset for molecular property prediction, originally derived from MoleculeNet and adapted by the Stanford team as part of the Open Graph Benchmark. It contains 437,929 graphs, with each graph averaging 26 nodes and 28.1 edges. The supported task of this dataset is molecular property prediction, specifically binary classification tasks involving 128 attributes. The evaluation metric for the dataset is the average precision (AP) across tasks. The dataset structure includes fields such as node features, edge indices, edge attributes, labels, and the number of nodes. The dataset can be loaded via the PyGeometric library.
