from prt_rl.common.policy import RandomPolicy
from prt_rl.env.wrappers import GymnasiumWrapper
from prt_rl.common.runners import Runner

Create the environment

env = GymnasiumWrapper(
    gym_name="CarRacing-v3",
    render_mode="rgb_array",
    continuous=True,
)

Initialize Random policy

Create a random policy that takes in the environment parameters.

policy = RandomPolicy(env_params=env.get_parameters())

runner = Runner(
    env=env,
    policy=policy,
    recorder=GifRecorder(
        filename="car_race.gif",
        fps=50
    ),
