Wrappers

Miniworld include several built in wrapper available to researchers in miniworld.wrappers

class miniworld.wrappers.PyTorchObsWrapper(env)

Transpose the observation image tensors for PyTorch

class miniworld.wrappers.GreyscaleWrapper(env)

Convert image observations from RGB to greyscale

class miniworld.wrappers.StochasticActionWrapper(env, prob: float = 0.9, random_action: int | None = None)

Add stochasticity to the actions

If a random action is provided, it is returned with probability 1 - prob. Else, a random action is sampled from the action space.
