Chemprop is a Python package implementing message passing neural networks (MPNNs) for predicting molecular and reaction properties. It provides both a Python API and a command-line interface for training, evaluating, and applying graph neural network models on chemical datasets.

Use cases

• predict molecular properties from SMILES strings
• train a graph neural network on chemical property data
• predict reaction properties with learned representations
• screen drug candidate molecules for desired properties
• run hyperparameter optimization for molecular property models
• interpret which atoms drive a property prediction

When to choose

• you need state-of-the-art MPNN models for molecular property prediction
• you want a maintained, well-documented tool with CLI and Python API for cheminformatics ML
• you are doing drug discovery or materials research requiring property prediction

When to avoid

• you need general-purpose graph neural networks beyond molecular graphs
• you want a no-code GUI tool rather than Python/CLI workflows
• your data is not chemical structures or reactions
