Properties

network

The full name of the Google Compute Engine network to which this CustomJob should be peered.

Takes the format projects/{project}/global/networks/{network}. Where {project} is a project number, as in 12345, and {network} is a network name.

Private services access must already be configured for the network. If left unspecified, the CustomJob is not peered with any network.

run

run(
    service_account: Optional[str] = None,
    network: Optional[str] = None,
    timeout: Optional[int] = None,
    restart_job_on_worker_restart: bool = False,
    tensorboard: Optional[str] = None,
    sync: bool = True,
)

Run this configured CustomJob.

Parameters

Name	Description
service_account	str Optional. Specifies the service account for workload run-as account. Users submitting jobs must have act-as permission on this run-as account.
network	str Optional. The full name of the Compute Engine network to which the job should be peered. For example, projects/12345/global/networks/myVPC. Private services access must already be configured for the network. If left unspecified, the job is not peered with any network.
timeout	int The maximum job running time in seconds. The default is 7 days.
restart_job_on_worker_restart	bool Restarts the entire CustomJob if a worker gets restarted. This feature can be used by distributed training jobs that are not resilient to workers leaving and joining a job.
tensorboard	str Optional. The name of a Vertex AI Tensorboard resource to which this CustomJob will upload Tensorboard logs. Format: projects/{project}/locations/{location}/tensorboards/{tensorboard} The training script should write Tensorboard to following Vertex AI environment variable: AIP_TENSORBOARD_LOG_DIR service_account is required with provided tensorboard.
