I'm attempting to design an action space in OpenAI's gym and hitting the following roadblock. I've looked at this post which is closely related but subtly different.
The environment I'm writing needs to allow an agent to make between $1$ and $n$ sub-actions in each step. Leaving it up to the agent to decide how many sub-actions it wants to take. So, something like (sub-action-category, sub-action-id, action) where the agent can specify between $1$ and $n$ such tuples.
It doesn't seem possible to define a
Box space without specifying bounds on the shape which is what I need here. I'm trying to avoid defining an action space where each sub-action is explicitly enumerated by the environment like (action) tuple with n entries for each sub-action.
Are there any other spaces I could use to dynamically scale the space?
