[BUG] Unable to calculate relative force deviation.

[xiaohe-njust]

Bug summary

When using dpgen for structural exploration, if an external LAMMPS template is used, the relative force model deviation cannot be calculated, and the output model_devi.out file information is the absolute force deviation. When no external LAMMPS template is used, everything is normal.

DP-GEN Version

0.12.1

"use_relative": true, "epsilon": 1.0,
If an external LAMMPS template is used, regardless of whether the code for calculating relative force deviation is used, the output model_devi.out file information remains the same. Trying to change the value of the keyword epsilon still has no effect. When no external LAMMPS template is used, everything is normal.

This is actually the same problem as #1608
