Constructor Details

BigGANTranslator

public BigGANTranslator(float truncation)

Constructs a translator for BigGAN.

Parameters:

truncation - value used to scale the normal seed for BigGAN

Method Details

processOutput

public Image[] processOutput(TranslatorContext ctx,
 NDList list)

Processes the output NDList to the corresponding output object.

Specified by:

processOutput in interface PostProcessor<Image[]>

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,
 int[] input)
                    throws Exception

Processes the input and converts it to NDList.

Specified by:

processInput in interface PreProcessor<int[]>

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
