Specifies a new array observation. This represents an observation made up of an Array of some other observation. This Array can be variable in size (up to some fixed maximum size) and the order of elements is taken into consideration. Internally this observation uses Attention so can be slower to evaluate and more difficult to train than other observation types. For this reason it should be used sparingly.
Target is Learning Agents Observations
