where is the `observation_utils`?

following the tutorial here: https://flatland.aicrowd.com/getting-started/rl/single-agent.html

The fourth line of :

from flatland.envs.rail_env import RailEnv
from flatland.envs.rail_generators import sparse_rail_generator
from flatland.envs.schedule_generators import sparse_schedule_generator
from utils.observation_utils import normalize_observation
from flatland.envs.observations import TreeObsForRailEnv

there is actually no utils. And under flatland.utils, there's no observation_utils...

Is the project updated? Where should I find that function?
