Branch dev_multiagent ModuleNotFoundError

[LAS1520]

Bug description

I pulled the branch dev_multiagent and installed from source. But when I tried to run base_test_random_multi_agents.py, I had a ModuleNotFoundError, which was caused by the grid2op.multi_agent.ma_typing.py.

How to reproduce

Code snippet

In base_test_random_multi_agents.py, I ran:

import pdb
import grid2op
from grid2op.Converter import IdToAct
from grid2op.multi_agent import MultiAgentEnv, SubGridObjects

Current output

ModuleNotFoundError                       Traceback (most recent call last)

ModuleNotFoundError: No module named 'getting_started'

The module 'getting_started' was used in grid2op.multi_agent.ma_typing.py:

from typing import Any, Optional, Dict, Tuple
from getting_started.grid2op.Observation.baseObservation import BaseObservation
from getting_started.grid2op.Observation.observationSpace import ObservationSpace

from grid2op.multi_agent.subgridAction import SubGridAction, SubGridActionSpace

AgentID = str

LocalObservationSpace = ObservationSpace
LocalActionSpace = SubGridActionSpace

LocalAction = SubGridAction
LocalObservation = BaseObservation

ActionProfile = Dict[AgentID, LocalAction]
MADict = Dict[AgentID, Any]  # TODO slit it in more things to be more precise
# this is close to useless this way

Maybe the two lines of the code above should be modified to

from grid2op.Observation.baseObservation import BaseObservation
from grid2op.Observation.observationSpace import ObservationSpace

Hello,

Indeed I already fixed that on the development branch in my repo that I did not merged here yet because some tests are failing and I don't really why at the moment. I am working on it and letting you know when I'll merge it.

Thanks for raising this error

In the merge, I will also include some examples on how to use the multi-agent feature with ray in a dedicated "examples/multi_agents" folder (accessible if you clone this repo)

I just merged the fix, you can clone it again if you want :-)

Thanks a lot!
