code Code (latest: v0.2.3)
Replicate our numerical results or reconstruct a force field from your own dataset with a Python implementation of sGDML.
Test a pre-trained model on one of the published datasets
1. Download the aspirin model & dataset.
$ sgdml-get model aspirin
$ sgdml-get dataset aspirin_dft2. Test the model on 10k data points.
$ sgdml test aspirin.npz aspirin_dft.npz 10000
