Hi have you solved it?

Any news on this bug? I was using carla normally just until this moment, then the same error appeared.

Boost.Python.ArgumentError: Python argument types in

    Map.get_waypoint(Map, NoneType)

did not match C++ signature:

    get_waypoint(carla::client::Map {lvalue}, carla::geom::Location location, bool project_to_road=True, int lane_type=carla.libcarla.LaneType.Driving) was raised from the environment creator for CarlaEnv-pt-v0 with kwargs ({'render': False, 'carla_port': 2000, 'changing_weather_speed': 0, 'frame_skip': 60, 'observations_type': 'state-waypoint', 'traffic': True, 'vehicle_name': 'toyota.prius', 'map_name': 'Town02', 'autopilot': False, 'agent_name': 'RL', 'other_ru': 0})

I have met this error, thanks very much.

@Daniel23-6 Just as explanation and fix self.agent.set_destination((120, 330, spawn_point_ego.location.z)) is wrong -> self.agent.set_destination(carla.Location(120, 330, spawn_point_ego.location.z)).

From what I can see this is a bug in another repository that was used.

Something called map.get_waypoint(None) without a traceback one cannot tell where this error comes from.
