assign_backing_tensorboard

assign_backing_tensorboard(
    tensorboard: typing.Union[
        google.cloud.aiplatform.tensorboard.tensorboard_resource.Tensorboard, str
    ]

my_experiment = aiplatform.Experiment('my-experiment')
my_experiment.assign_backing_tensorboard(tb)

Parameter
Name	Description
`tensorboard`	`Union[aiplatform.Tensorboard, str]` Required. Tensorboard resource or resource name to associate to this experiment.

Exceptions
Type	Description
`ValueError`	If this experiment already has a previously set backing tensorboard resource.
`ValueError`	If Tensorboard is not in same project and location as this experiment.

    location: typing.Optional[str] = None,
    credentials: typing.Optional[google.auth.credentials.Credentials] = None
) -> google.cloud.aiplatform.metadata.experiment_resources.Experiment

Creates a new experiment in Vertex AI Experiments.

my_experiment = aiplatform.Experiment.create('my-experiment', description='my description')

Parameters
Name	Description
`experiment_name`	`str` Required. The name of this experiment.

`location`	`str` Optional. Location where this experiment will be created. Overrides location set in aiplatform.init.
`credentials`	`auth_credentials.Credentials` Optional. Custom credentials used to create this experiment. Overrides credentials set in aiplatform.init.

delete

delete(*, delete_backing_tensorboard_runs: bool = False)

Deletes this experiment all the experiment runs under this experiment

Does not delete Pipeline runs, Artifacts, or Executions associated to this experiment or experiment runs in this experiment.

my_experiment = aiplatform.Experiment('my-experiment')
my_experiment.delete(delete_backing_tensorboard_runs=True)

Parameter
Name	Description
`delete_backing_tensorboard_runs`	`bool` Optional. If True will also delete the Tensorboard Runs associated to the experiment runs under this experiment that we used to store time series metrics.
