Model Card for mace-universal / mace-mp

MACE-MP is a pretrained general-purpose foundational interatomic potential published with the preprint arXiv:2401.00096.

This repository is the original place I put the first universal MACE model back in 2024 summer before everything happens, and has became the archive of pretrained checkpoints for manual loading using MACECalculator or further fine-tuning. Now the easiest way to use models is to follow the documentation for foundtional models. All the models are trained with MPTrj data, Materials Project relaxation trajectories compiled by CHGNet authors to cover 89 elements and 1.6M configurations. The checkpoint was used for materials stability prediction on Matbench Discovery and the associated preprint.

MACE (Multiple Atomic Cluster Expansion) is a machine learning interatomic potential (MLIP) with higher order equivariant message passing. For more information about MACE formalism, please see authors' paper.

Usage

(optional) Install Pytorch, ASE prerequisites for preferred version
Install MACE through GitHub (not through pypi)

pip install git+https://github.com/ACEsuit/mace.git

Use MACECalculator

python

from mace.calculators import MACECalculator
from ase import Atoms, units
from ase.build import bulk
from ase.md.npt import NPT

atoms = bulk("NaCl", crystalstructure='rocksalt', a=3.54, cubic=True)

calculator = MACECalculator(
  model_paths=/path/to/pretrained.model,
  device=device,
  default_dtype="float32" or "float64",
)

atoms.calc = calculator

dyn = NPT(
  atoms=atoms,
  timestep=timestep,
  temperature_K=temperature,
  externalstress=externalstress,
  ttime=ttime,
  pfactor=pfactor,
)

dyn.run(steps)

Training Guide

Training Data

For now, please download MPTrj data from figshare. We may upload to HuggingFace Datasets in the future.

Fine-tuning

We provide an example multi-GPU training script 2023-08-14-mace-universal.sbatch, which uses 40 A100s on NERSC Perlmutter. Please see MACE multi-gpu branch for more detailed instructions.
