LAMMPS-MLIP interface

I’m trying to run a simple code with two atom types by the LAMMPS-MLIP interface (MLIP version 2), but I’m unable to find how I should define the pair_coefficients.
For just one atom type it works in the following way:
pair_style mlip mlip.ini
pair_coeff * *

The mlip.ini contains the name of the .mtp potential.

MLIP is not part of the canonical LAMMPS distribution, I don’t know anything about it.
You need to contact the LAMMPS-MLIP developer(s) directly for questions.
