Is it possible to mix DeepMD potential with classical potentials (e.g., Tersoff) in LAMMPS?

[Ceciliaviar]

Hi developers,
I am trying to run a mixed-potential LAMMPS simulation that combines a DeepMD potential and a classical potential (Tersoff).
Here is the simplified part of my in.lammps file:

pair_style hybrid deepmd graph.pb tersoff
pair_coeff * * deepmd graph.pb Si C
pair_coeff * * tersoff SiC.tersoff Si C

However, LAMMPS returns
ERROR: Pair style deepmd hybrid not compatible with pair hybrid (src/pair_deepmd.cpp:123)_

So, I’d like to confirm:_

1. Is deepmd currently compatible with pair_style hybrid?
2. If yes, could you please share the correct syntax or an example?
3. If not, are there any recommended coupling approaches to combine DeepMD with other potentials?
   Thanks a lot for your guidance and for developing such a great tool!
   Best,

I don't find where this error comes from, but at least, according to the LAMMPS documentation, your command is incorrect.

With the hybrid style, exactly one pair style is assigned to each pair of atom types.
