SplitActionsWrapper
(*args, **kwds)¶ Splits an actions into separate ones.
An example is given by the LunarLanderContinuous-v2 env. Here we have a box action spaces with shape (2,) such that dimension 0 is the up/down action and dimension 1 is the left/right action. Now if we would like to split this action correspondingly we can wrap the env with the following config:
- split_config:
- action:
- action_up:
indices: [0]
- action_side:
indices: [1]
Now the actions as well as the action space is consists of two actions (action_up/action_side).
- Parameters
env – Environment/wrapper to wrap.
split_config – The action splitting configuration.
