modelforge curated dataset: QM9
收藏资源简介:
Modelforge Curated QM9 Dataset:- Full dataset- Version: full_dataset_v1.1: This provides a curated hdf5 file for a subset of the QM9 dataset to be used for testing purposes, designed to be compatible with modelforge, an infrastructure to implement and train NNPs. This test dataset contains 133885 systems with a single configuration for each unique molecule. When applicable, the units of properties are provided in the datafile, encoded as strings compatible with the openff-units package.
