ServingTranslator	A Translator that can handle generic Input and Output.
Transform	An interface to apply various transforms to the input.
Translator<I,O>	The Translator interface provides model pre-processing and postprocessing functionality.
TranslatorContext	The TranslatorContext interface provides a toolkit for pre-processing and postprocessing functionality.
TranslatorFactory	A utility class creates Translator instances.

Pipeline	Pipeline allows applying multiple transforms on an input NDList.
ServingTranslatorFactory	A TranslatorFactory that creates a generic Translator.
SimplePaddingStackBatchifier	A simpler version of the PaddingStackBatchifier that pads all dimensions rather than specific ones.
StackBatchifier	StackBatchifier is used to merge a list of samples to form a mini-batch of NDArray(s).
