For now, we do not support using different spaces across agents
(i.e., all agents have to share the same brain in Arena-BuildingToolkit)
This is because we want to consider the transfer/sharing weight between agents.
If you do have completely different agents in the game, one harmless workaround is
to use the same brain, but define the different meaning of the action in Arena-BuildingToolkit.
