Example 1 with TextClassificationPredictionInstance

use of com.google.cloud.aiplatform.v1.schema.predict.instance.TextClassificationPredictionInstance in project java-aiplatform by googleapis.

the class PredictTextClassificationSingleLabelSample method predictTextClassificationSingleLabel.

    PredictionServiceSettings predictionServiceSettings = PredictionServiceSettings.newBuilder().setEndpoint("us-central1-aiplatform.googleapis.com:443").build();
    // the "close" method on the client to safely clean up any remaining background resources.
    try (PredictionServiceClient predictionServiceClient = PredictionServiceClient.create(predictionServiceSettings)) {
