Atari wrappers
WebStable Baselines3 provides SimpleMultiObsEnv as an example of this kind of of setting. The environment is a simple grid world but the observations for each cell come in the form of dictionaries. These dictionaries are randomly initialized on the creation of the environment and contain a vector observation and an image observation. WebWarning. Use this wrapper only with Atari v4 without frame skip: env_id = "*NoFrameskip-v4". Parameters: env ( Env) – Environment to wrap. noop_max ( int) – Max number of no …

Webclip_range_vf behavior for PPO is slightly different: Set it to None (default) to deactivate clipping (in SB2, you had to pass -1, None meant to use clip_range for the clipping). lam-> gae_lambda. noptepochs-> n_epochs. PPO default hyperparameters are the one tuned for continuous control environment. We recommend taking a look at the RL Zoo for …
