In order to wrap an environment, you must first initialize a base environment. Then you can pass this environment along with (possibly optional) parameters to the wrapper's constructor:
```python
>>> import gymnasium
>>> from gymnasium.wrappers import RescaleAction
>>> base_env = gymnasium.make("BipedalWalker-v3")
>>> base_env.action_space
Box([-1. -1. -1. -1.], [1. 1. 1. 1.], (4,), float32)
>>> wrapped_env = RescaleAction(base_env, min_action=0, max_action=1)
>>> wrapped_env.action_space
Box([0. 0. 0. 0.], [1. 1. 1. 1.], (4,), float32)
>>> import gymnasium as gym
>>> from gymnasium.wrappers import FlattenObservation
>>> env = gym.make("CarRacing-v2")
>>> env.observation_space.shape
