Constructor Detail

NoopTranslator

public NoopTranslator(Batchifier batchifier)

Constructs a NoopTranslator with the given Batchifier.

Parameters:

batchifier - batchifier to use

NoopTranslator

public NoopTranslator()

Constructs a NoopTranslator.

Method Detail

processInput

public NDList processInput(TranslatorContext ctx,
                           NDList input)

Processes the input and converts it to NDList.

Specified by:

processInput in interface PreProcessor<NDList>

Parameters:

ctx - the toolkit for creating the input NDArray

input - the input object

Returns:

the NDList after pre-processing

processOutput

public NDList processOutput(TranslatorContext ctx,
                            NDList list)

Processes the output NDList to the corresponding output object.

Specified by:

processOutput in interface PostProcessor<NDList>

Parameters:

ctx - the toolkit used for post-processing

list - the output NDList after inference, usually immutable in engines like PyTorch. @see Issue 1774

Returns:

the output object of expected type

getBatchifier

public Batchifier getBatchifier()

Returns the Batchifier.

Specified by:

getBatchifier in interface Translator<NDList,NDList>

Returns:

the Batchifier

setBatchifier

public void setBatchifier(Batchifier batchifier)

Sets the Batchifier for the Translator.

Parameters:

batchifier - the Batchifier for the Translator
