Machine Learning Force Fields (MLFFs) require ongoing improvement and innovation to effectively address challenges across various domains. Developing MLFF models typically involves extensive screening, tuning, iterative testing. However, existing packages based on a single mature descriptor or model are unsuitable for this process. Therefore, we developed package named ABFML, PyTorch, which aims promote by providing developers with rapid, efficient, user-friendly tool constructing,...
