[BindServiceMethod(typeof(PredictionService), "BindService")]
public abstract class PredictionService.PredictionServiceBase

Reference documentation and code samples for the Google AutoML v1 API class PredictionService.PredictionServiceBase.

Base class for server-side implementations of PredictionService

Inheritance

object > PredictionService.PredictionServiceBase

Namespace

Google.Cloud.AutoML.V1

Assembly

Google.Cloud.AutoML.V1.dll

Methods

BatchPredict(BatchPredictRequest, ServerCallContext)

public virtual Task<Operation> BatchPredict(BatchPredictRequest request, ServerCallContext context)

Perform a batch prediction. Unlike the online [Predict][google.cloud.automl.v1.PredictionService.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][google.longrunning.Operations.GetOperation] method. Once the operation is done, [BatchPredictResult][google.cloud.automl.v1.BatchPredictResult] is returned in the [response][google.longrunning.Operation.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
Parameters
Name Description
request BatchPredictRequest

The request received from the client.

context ServerCallContext

The context of the server-side call handler being invoked.

Returns
Type Description
TaskOperation

The response to send back to the client (wrapped by a task).

Predict(PredictRequest, ServerCallContext)

public virtual Task<PredictResponse> Predict(PredictRequest request, ServerCallContext context)
