In order to run without any problems the simulator you need to edit the __init__.py
file in notebooks/simulator/src/gym_duckietown/envs
as follow:
# coding=utf-8
# noinspection PyUnresolvedReferences
from ..wrappers import DiscreteWrapper
from ..envs.duckietown_env import DuckietownEnv
from ..envs.duckiebot_env import DuckiebotEnv
from ..envs.multimap_env import MultiMapEnv
The original file looks like :
# coding=utf-8
# noinspection PyUnresolvedReferences
from gym_duckietown.wrappers import DiscreteWrapper
from gym_duckietown.envs.duckietown_env import DuckietownEnv
from gym_duckietown.envs.duckiebot_env import DuckiebotEnv
from gym_duckietown.envs.multimap_env import MultiMapEnv
