In GCP Vertex AI, why is Delete Training Pipeline REST endpoint unimplemented?

I used this code, straight from the Javadocs, to delete a VertexAI Training Pipeline

try (PipelineServiceClient pipelineServiceClient = PipelineServiceClient.create()) {
  TrainingPipelineName name =
      TrainingPipelineName.of("[PROJECT]", "[LOCATION]", "[TRAINING_PIPELINE]");
  pipelineServiceClient.deleteTrainingPipelineAsync(name).get();
}

I get this error. From what I can see, this means that this API, though officially documented, is simply unimplemented. How do we delete Training Pipelines using Java?

Error in deleting //aiplatform.googleapis.com/projects/746859988231/locations/us-central1/trainingPipelines/186468439399187392:

Solution

  • According to the official documentation, https://cloud.google.com/vertex-ai/docs/reference/rest , the supported service URLs for this service are:

    https://us-central1-aiplatform.googleapis.com
https://us-east1-aiplatform.googleapis.com
https://us-east4-aiplatform.googleapis.com
https://us-west1-aiplatform.googleapis.com
https://northamerica-northeast1-aiplatform.googleapis.com
https://europe-west1-aiplatform.googleapis.com

https://asia-northeast1-aiplatform.googleapis.com
https://asia-northeast3-aiplatform.googleapis.com
https://asia-southeast1-aiplatform.googleapis.com
https://australia-southeast1-aiplatform.googleapis.com

      PipelineServiceSettings pipelineServiceSettings =
        PipelineServiceSettings.newBuilder()
            .setEndpoint("us-central1-aiplatform.googleapis.com:443")
            .build();

     try (PipelineServiceClient pipelineServiceClient =
      PipelineServiceClient.create(pipelineServiceSettings)) {

  String location = "us-central1";
  TrainingPipelineName trainingPipelineName =
      TrainingPipelineName.of(project, location, trainingPipelineId);

  OperationFuture<Empty, DeleteOperationMetadata> operationFuture =
      pipelineServiceClient.deleteTrainingPipelineAsync(trainingPipelineName);

  System.out.format("Operation name: %s\n", operationFuture.getInitialFuture().get().getName());
  System.out.println("Waiting for operation to finish...");
  operationFuture.get(300, TimeUnit.SECONDS);

  System.out.format("Deleted Training Pipeline.");
