Experimental setting for Symbolic/FullyObs Wrappers

[sbhambr1]

Hi, thanks for the great repository!

Is there any support or existing experimental settings with an architecture for the ACModel that works with fully observable or symbolic wrapper (observation space: (5,5,3)?

My experiment setting:
--env "MiniGrid-DoorKey-5x5-v0"
--algo "ppo"

Any help will be greatly appreciated!
