How can I discretize an observation_space=Box(128, 128, 3) using DiscretizedObservationWrapper class? please explain with example!!

Its been quite some time since I've worked on this library. If you have a gym environment env with a bounded, continuous observation space, then in order to get a discrete version you have to create a new environment as

discrete = space_wrappers.DiscretizedObservationWrapper(env, steps)

where steps is the number of discrete steps you want. For a Box environment, you can also specify a separate number of steps for each dimension.
