Error with the PettingZooWrapper?

[eperm17]

Hello everyone!

I am trying to use the PettingZooWrapper for the Scenario1b, following the tutorial explained on the "1.Introduction.ipynb" notebook.

Although the example (DroneSwarmScenarioGenerator) given in this notebook works perfectly well with the PEttingZooWrapper, when I try to do the same with the FileReaderScenarioGenerator (code below), I get an error.

from CybORG.Simulator.Scenarios import FileReaderScenarioGenerator
from CybORG import CybORG
from CybORG.Agents.Wrappers import PettingZooParallelWrapper

path = inspect.getfile(CybORG)
path = '/Simulator/Scenarios/scenario_files/Scenario1b.yaml'
sg = FileReaderScenarioGenerator(path)
cyborg = CybORG(scenario_generator=sg)

env = PettingZooParallelWrapper(cyborg)
obs = env.reset()
print(obs.keys())

The error I get:

---

AttributeError Traceback (most recent call last)

Thanks a lot in advance!
