Issue creating LAMMPS model from EnergyDipoleMACE model
lemessuriernb opened this issue · 3 comments
I would like to test my inital MACE model, but I keep getting an error when using the create_lammps_model.py to convert an EnergyDipoleMACE model. Is it possible to use this type of MACE model with LAMMPS?
Error:

Hey,
It is not currently possible to use the EnergyDipole model in lammps. Why ASE is not sufficient for you?
Hi,
I see. Is this a feature that may be added in the future?
I will see if ASE has the functionality I need, but my initial interest in MACE was because it interfaced with LAMMPS.
Which MACE models can be used with LAMMPS?
Is EnergyDipole only usable with ASE? Or will it work with OpenMM at all?
Thank you.
The MACE and ScaleShiftMACE models are the only one with a LAMMPS interface. If you have scripts that run in LAMMPS I recommend you train a normal MACE force field, do your trajectory and then evaluate the DipoleMACE on the trajectory to get all the dipoles. It will be identical.
It is not in our priorities at the moment.
