Method Detail

processOutput

public java.lang.String processOutput(TranslatorContext ctx,
                                      NDList list)

Processes the output NDList to the corresponding output object.

Specified by:

processOutput in interface PostProcessor<java.lang.String>

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

processInput

public NDList processInput(TranslatorContext ctx,
                           java.lang.String input)

Processes the input and converts it to NDList.

Specified by:

processInput in interface PreProcessor<java.lang.String>

Parameters:

ctx - the toolkit for creating the input NDArray

input - the input object

Returns:

the NDList after pre-processing

getBatchifier

public Batchifier getBatchifier()

Returns the Batchifier.

Specified by:

getBatchifier in interface Translator<java.lang.String,java.lang.String>

Returns:

the Batchifier
