Using M3GNETCalculator

[Viba97]

Dear developers,

I'm trying to figure out how to use M3GNETCalculator directly on ASE if it is possible. This is very short code that I've tried to setup but I'm still facing the same error

`import os
import ase
import m3gnet
from m3gnet.models import M3GNetCalculator, Potential

atoms=ase.io.read('xtbopt.xyz')
atoms.calc=M3GNetCalculator(potential=Potential)
energy = atoms.get_potential_energy()`

which returns:

Traceback (most recent call last):
File "", line 1, in
File "/opt/homebrew/Caskroom/miniforge/base/envs/m3gnet/lib/python3.9/site-packages/ase/atoms.py", line 731, in get_potential_energy
energy = self._calc.get_potential_energy(self)
File "/opt/homebrew/Caskroom/miniforge/base/envs/m3gnet/lib/python3.9/site-packages/ase/calculators/calculator.py", line 709, in get_potential_energy
energy = self.get_property('energy', atoms)
File "/opt/homebrew/Caskroom/miniforge/base/envs/m3gnet/lib/python3.9/site-packages/ase/calculators/calculator.py", line 737, in get_property
self.calculate(atoms, [name], system_changes)
File "/opt/homebrew/Caskroom/miniforge/base/envs/m3gnet/lib/python3.9/site-packages/m3gnet/models/_dynamics.py", line 84, in calculate
graph = self.potential.graph_converter(atoms)
AttributeError: module 'Potential' has no attribute 'graph_converter'

What am I missing?

Thank you for your help
