This simplifies the creation of custom training\njobs. All inputs and outputs of the supplied component will be copied over to\nthe constructed training job operator.\n\nNote that this utility constructs a `ClusterSpec`, where the primary and all the\nworkers use the same specification, meaning all disk and machine\nspecification-related parameters will apply to all replicas. This is suitable\nfor use cases where, for example, you are training with\n[`MultiWorkerMirroredStrategy`](https://www.tensorflow.org/api_docs/python/tf/distribute/experimental/MultiWorkerMirroredStrategy) or\n[`MirroredStrategy`](https://www.tensorflow.org/api_docs/python/tf/distribute/MirroredStrategy).\n\nThis component does not support `CustomJob` Python package training, or\ndistributed training with different worker pool specs.\n\nAPI reference\n-------------\n\n- For component reference, see the [Google Cloud SDK reference for CustomJob components](https://google-cloud-pipeline-components.readthedocs.io/en/google-cloud-pipeline-components-2.19.0/api/v1/custom_job.html).\n- For Vertex AI API reference, see the [`CustomJob` resource](/vertex-ai/docs/reference/rest/v1/projects.locations.customJobs) page.\n\nVersion history and release notes\n---------------------------------\n\nTo learn more about the version history and changes to the Google Cloud Pipeline Components SDK, see the [Google Cloud Pipeline Components SDK Release Notes](https://google-cloud-pipeline-components.readthedocs.io/en/google-cloud-pipeline-components-2.19.0/release.html).\n\nTechnical support contacts\n--------------------------\n\nIf you have any questions, reach out to\n[kubeflow-pipelines-components@google.com](mailto: kubeflow-pipelines-components@google.com)."]]
