Why not correctly predict the energy by using deepmd.calculator in ASE?

[taipinghu]

Dear developers,
I want to predict the energy using deepmd.calculator in ASE module according to the https://github.com/deepmodeling/deepmd-kit/blob/master/doc/third-party/ase.md, but some errors occur. The obtained energy is not correct.
My code is :
`#!/bin/env python

from ase import Atoms
from deepmd.calculator import DP

import ase.io as IO

system_ase = IO.read("OUTCAR")
print(system_ase.get_potential_energy())

import dpdata
system_dpdata = dpdata.LabeledSystem("OUTCAR", fmt="vasp/outcar")
print(system_dpdata["energies"][0])
atype = system_dpdata["atom_types"]

system_ase_tmp = Atoms("Li12Co12O24", positions=system_ase.get_positions(), cell=system_ase.get_cell(), calculator=DP(model="graph.000.pb"))
print(system_ase_tmp.get_potential_energy())

from deepmd.infer import DeepPot
import numpy as np
dp = DeepPot("graph.000.pb")
coordinate = np.array(system_ase.get_positions()).reshape([1, -1])
cell = np.array(system_ase.get_cell()).reshape([1, -1])
e, f, v = dp.eval(coordinate, cell, atype)
print(e)`

the output of the code is:

You did not set correct pbc in ASE. Refer https://wiki.fysik.dtu.dk/ase/ase/atoms.html#ase.Atoms.

You did not set correct pbc in ASE. Refer https://wiki.fysik.dtu.dk/ase/ase/atoms.html#ase.Atoms.

OK, Thanks a lot.
when pbc was used in ase.Atoms, the output is normal.
