PreProcessor¶
-
class
maze.core.wrappers.observation_preprocessing.preprocessors.base.PreProcessor(observation_space: gym.spaces.Space, **kwargs)¶ Interface for observation pre-processors. Pre-processors implementing this interface can be used in combination with the
PreProcessingWrapper.- Parameters
observation_space – The observation space to pre-process.
kwargs – Arguments to be passed on to preprocessor’s constructor.
-
abstract
process(observation: numpy.ndarray) → numpy.ndarray¶ Pre-processes the observation.
- Parameters
observation – The observation to pre-process.
- Returns
The pre-processed observation.
-
abstract
processed_shape() → Tuple[int, …]¶ Computes the observation’s shape after pre-processing.
- Returns
The resulting shape.
-
abstract
processed_space() → gym.spaces.Box¶ Modifies the given observation space according to the respective pre-processor.
- Returns
The updated observation space.
