frames are set to indicate the reward at each step. Default `False`.
render_kwargs: Dict, render kwargs for pixel wrapper.
pixels_only: Boolean controlling the exclusion of states in the observation.
pixels_observation_key: Key in the observation used for the rendered image.
env_state_wrappers: Env state wrappers to be called before the PixelWrapper.
Returns:
