paire style problem

[WU2JING]

Hello everyone, when I try to use three deep potential models defining paire_style in lammps. However, I encountered an error, as shown in the figure. I am stuck in the problem for a long time.
Any discussion is welcomed. Thank you.

The suggested option is to put the training data of BAsGaN, BAs and GaN together, and train a DP model out of them.

The hybridization of models does not really make sense.
