public Sam2ServingTranslator(Sam2Translator translator)

Constructs a new Sam2ServingTranslator instance.

Parameters:

translator - a Sam2Translator

Method Details

getBatchifier

public Batchifier getBatchifier()

Returns the Batchifier.

Specified by:

getBatchifier in interface Translator<Input,Output>

Returns:

the Batchifier

processOutput

public Output processOutput(TranslatorContext ctx,
 NDList list)
                     throws IOException

Processes the output NDList to the corresponding output object.

Specified by:

processOutput in interface PostProcessor<Output>

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

Throws:

IOException

processInput

public NDList processInput(TranslatorContext ctx,
 Input input)
                    throws Exception

Processes the input and converts it to NDList.

Specified by:

processInput in interface PreProcessor<Input>

Parameters:

ctx - the toolkit for creating the input NDArray

input - the input object

Returns:

the NDList after pre-processing

Throws:

Exception - if an error occurs during processing input

prepare

public void prepare(TranslatorContext ctx)
             throws Exception

Prepares the translator with the manager and model to use.

Specified by:

prepare in interface Translator<Input,Output>

Parameters:

ctx - the context for the Predictor.

Throws:

Exception - if there is an error for preparing the translator
