Class PredictionServiceGrpc.PredictionServiceFutureStub (2.45.0) 

public static final class PredictionServiceGrpc.PredictionServiceFutureStub extends AbstractFutureStub<PredictionServiceGrpc.PredictionServiceFutureStub>

A stub to allow clients to do ListenableFuture-style rpc calls to service PredictionService.

AutoML Prediction API. On any input that is documented to expect a string parameter in snake_case or dash-case, either of those cases is accepted.

Methods

batchPredict(BatchPredictRequest request)

public ListenableFuture<Operation> batchPredict(BatchPredictRequest request)

Perform a batch prediction. Unlike the online Predict, batch prediction result won't be immediately available in the response. Instead, a long running operation object is returned. User can poll the operation result via GetOperation method. Once the operation is done, BatchPredictResult is returned in the response field. Available for following ML scenarios:

  • AutoML Vision Classification
  • AutoML Vision Object Detection
  • AutoML Video Intelligence Classification
  • AutoML Video Intelligence Object Tracking * AutoML Natural Language Classification
  • AutoML Natural Language Entity Extraction
  • AutoML Natural Language Sentiment Analysis
  • AutoML Tables

predict(PredictRequest request)

public ListenableFuture<PredictResponse> predict(PredictRequest request)

  • A TextSnippet up to 60,000 characters, UTF-8 encoded or a document in .PDF, .TIF or .TIFF format with size upto 2MB. AutoML Natural Language Entity Extraction
  • A TextSnippet up to 10,000 characters, UTF-8 NFC encoded or a document in .PDF, .TIF or .TIFF format with size upto 20MB. AutoML Natural Language Sentiment Analysis
  • A TextSnippet up to 60,000 characters, UTF-8 encoded or a document in .PDF, .TIF or .TIFF format with size upto 2MB. AutoML Translation
  • A TextSnippet up to 25,000 characters, UTF-8 encoded. AutoML Tables
  • A row with column values matching the columns of the model, up to 5MB. Not available for FORECASTING prediction_type.
