在 GCP Vertex AI 中，为什么没有实现 Delete Training Pipeline REST 端点？答案

【问题标题】：In GCP Vertex AI, why is Delete Training Pipeline REST endpoint unimplemented?在 GCP Vertex AI 中，为什么没有实现 Delete Training Pipeline REST 端点？

【问题描述】：

我直接使用 Javadocs 中的 this code 删除了 VertexAI 训练管道

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

我收到此错误。据我所知，这意味着这个 API 虽然有官方文档，但根本没有实现。我们如何使用 Java 删除训练管道？

根据官方文档https://cloud.google.com/vertex-ai/docs/reference/rest，该服务支持的服务URL为：

https://us-central1-aiplatform.googleapis.com
https://us-east1-aiplatform.googleapis.com
https://us-east4-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.");
}

就是这样！有什么不同？只是那个非标准端点？您知道这是应该要求 Google 修复的错误，还是只是我不太了解的标准行为？
请看编辑@JoshuaFox 特定端点支持该服务
谢谢。我提交了修复文档的错误请求：我要求他们添加 setEndpoint() 调用
