Potential issue with shortest path or success criteria in ObjectNav about habitat-challenge HOT 3 CLOSED

@devendrachaplot looking into this. If that the case, most probably issue is with shortest path, not metrics itself.

from habitat-challenge.

@devendrachaplot, checked the episodes. For portion of the episodes shortest path will not lead to success. Success distance is 0.1m to a view point of the target object, but shortest path sometimes stops up to 0.2m.
I would advice use new Shortestpath Planner instead of precalculated shortest paths:

goal_radius = config.TASK.SUCCESS.SUCCESS_DISTANCE / 2
follower = ShortestPathFollower(env.habitat_env.sim, goal_radius, False)
env.reset()
        while not env.habitat_env.episode_over:
            best_action = follower.get_next_action(
                closest_view_point.agent_state.position,
            )
            observations, reward, done, info = env.step(best_action)

With original shortest path (No success, distance_to_goal: 0.17m):

With new Shortestpath Planner: (Success, distance_to_goal: 0.04m):

Great, thanks a lot!

I had one quick follow-up question:
"Success distance is 0.1m to a view point of the target object" -> How are these view points obtained?
