fairchem-core 1.2.0

Machine learning models for use in catalysis as part of the Open Catalyst Project

fairchem by FAIR Chemistry

fairchem is the FAIR Chemistry's centralized repository of all its data, models, demos, and application efforts for materials science and quantum chemistry.

fairchem provides training and evaluation code for tasks and models that take arbitrary chemical structures as input to predict energies / forces / positions / stresses, and can be used as a base scaffold for research projects. For an overview of tasks, data, and metrics, please read the documentations and respective papers:

• OC20
• OC22
• ODAC23

Acknowledgements

• This codebase was initially forked from CGCNN by Tian Xie, but has undergone significant changes since.
• A lot of engineering ideas have been borrowed from github.com/facebookresearch/mmf.
• The DimeNet++ implementation is based on the author's Tensorflow implementation and the DimeNet implementation in Pytorch Geometric.
