mgp.py: raise ValueError(rebuild_dict, newbound_dict, err_str)

[smc-lucky]

Recently, I try to use FLARE according to the tutorials "on-the-fly training using ASE", But I am in trouble.
My calculated system is "GeTe" (64-atoms structure), I want to get an accurate potential to run MD with LAMMPS.
There are a question:
1. file "/usr/local/lib/python3.6/dist-packages/flare/mgp/mgp.py", line 213, in predict
raise ValueError(rebuild_dict, newbound_dict, err_str)

My part input is as below:
  """
 from flare.ase.calculator import FLARE_Calculator
 flare_calculator = FLARE_Calculator(gp_model,
                                par = True,
                                mgp_model = mgp_model,
                                use_mapping = True)
super_cell.set_calculator(flare_calculator)
"""



I hold a view that my input might be fault. 
My input file is attached.
