我正在尝试使用 Vertex AI 上的 Kubeflow 管道运行自定义包训练管道。我将培训代码打包在 Google Cloud Storage 中，我的管道是：

import kfp
from kfp.v2 import compiler
from kfp.v2.dsl import component
from kfp.v2.google import experimental
from google.cloud import aiplatform
from google_cloud_pipeline_components import aiplatform as gcc_aip

@kfp.dsl.pipeline(name=pipeline_name, pipeline_root=pipeline_root_path)
def pipeline():
        training_job_run_op = gcc_aip.CustomPythonPackageTrainingJobRunOp(
            project=project_id,
            display_name=training_job_name,
            model_display_name=model_display_name,
            python_package_gcs_uri=python_package_gcs_uri,
            python_module=python_module,
            container_uri=container_uri,
            staging_bucket=staging_bucket,
            model_serving_container_image_uri=model_serving_container_image_uri)

        # Upload model
        model_upload_op = gcc_aip.ModelUploadOp(
            project=project_id,
            display_name=model_display_name,
            artifact_uri=output_dir,
            serving_container_image_uri=model_serving_container_image_uri,
        )
        model_upload_op.after(training_job_run_op)

        # Deploy model
        model_deploy_op = gcc_aip.ModelDeployOp(
            project=project_id,
            model=model_upload_op.outputs["model"],
            endpoint=aiplatform.Endpoint(
                endpoint_name='0000000000').resource_name,
            deployed_model_display_name=model_display_name,
            machine_type="n1-standard-2",
            traffic_percentage=100)

    compiler.Compiler().compile(pipeline_func=pipeline,
                                package_path=pipeline_spec_path)

当我尝试在 Vertex AI 上运行此管道时，出现以下错误：

{
  "insertId": "qd9wxrfnoviyr",
  "jsonPayload": {
    "levelname": "ERROR",
    "message": "google.api_core.exceptions.InvalidArgument: 400 List of found errors:\t1.Field: job_spec.worker_pool_specs; Message: At least one worker pool should be specified.\t\n"
  }
}

我的原件CustomPythonPackageTrainingJobRunOp没有定义worker_pool_spec错误的原因。在我指定replica_count并machine_type解决错误之后。最终训练操作是：

training_job_run_op = gcc_aip.CustomPythonPackageTrainingJobRunOp(
            project=project_id,
            display_name=training_job_name,
            model_display_name=model_display_name,
            python_package_gcs_uri=python_package_gcs_uri,
            python_module=python_module,
            container_uri=container_uri,
            staging_bucket=staging_bucket,
            base_output_dir=output_dir,
        model_serving_container_image_uri=model_serving_container_image_uri,
            replica_count=1,
            machine_type="n1-standard-4")
