Dist shift
MiniGrid's DistShift environment - two fixed layouts to test distribution shift.
See the environment class in this module for the task, layout and reward/termination details.
DistShift
Bases: Environment
Navix-DistShift1-v0 / Navix-DistShift2-v0. A small room with a
fixed strip of Lava between the player (top-left) and the goal
(top-right). The two ids differ only in where the lava's far edge
sits (split_lava), so a policy that overfits the first layout fails
on the second - the environment exists to test distribution shift.
Nothing is randomised.
