    *,
    project: typing.Optional[str] = None,
    location: typing.Optional[str] = None,
    credentials: typing.Optional[google.auth.credentials.Credentials] = None
)

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

Parameters
Name	Description
experiment_name	str Required. The name or resource name of this experiment. Resource name is of the format: projects/123/locations/us-central1/metadataStores/default/contexts/my-experiment
project	str Optional. Project where this experiment is located. Overrides project set in aiplatform.init.
location	str Optional. Location where this experiment is located. Overrides location set in aiplatform.init.
credentials	auth_credentials.Credentials Optional. Custom credentials used to retrieve this experiment. Overrides credentials set in aiplatform.init.

assign_backing_tensorboard

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

Assigns tensorboard as backing tensorboard to support time series metrics logging.

tb = aiplatform.Tensorboard('tensorboard-resource-id')
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.

create

create(
    experiment_name: str,
    *,
    description: typing.Optional[str] = None,
    project: typing.Optional[str] = None,
    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.
description	str Optional. Describes this experiment's purpose.
project	str Optional. Project where this experiment will be created. Overrides project set in aiplatform.init.
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.

get

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

Gets experiment if one exists with this experiment_name in Vertex AI Experiments.

Parameters
Name	Description
experiment_name	str Required. The name of this experiment.
project	str Optional. Project used to retrieve this resource. Overrides project set in aiplatform.init.
location	str Optional. Location used to retrieve this resource. Overrides location set in aiplatform.init.
credentials	auth_credentials.Credentials Optional. Custom credentials used to retrieve this resource. Overrides credentials set in aiplatform.init.

get_backing_tensorboard_resource

get_backing_tensorboard_resource() -> (
    typing.Optional[
        google.cloud.aiplatform.tensorboard.tensorboard_resource.Tensorboard
    ]
)

Get the backing tensorboard for this experiment if one exists.

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

get_data_frame

get_data_frame(*, include_time_series: bool = True) -> pd.DataFrame

Get parameters, metrics, and time series metrics of all runs in this experiment as Dataframe.

my_experiment = aiplatform.Experiment('my-experiment')
df = my_experiment.get_data_frame()

Parameter
Name	Description
include_time_series	bool Optional. Whether or not to include time series metrics in df. Default is True. Setting to False will largely improve execution time and reduce quota contributing calls. Recommended when time series metrics are not needed or number of runs in Experiment is large. For time series metrics consider querying a specific run using get_time_series_data_frame.

Exceptions
Type	Description
ImportError	If pandas is not installed.

Returns
Type	Description
pd.DataFrame	Pandas Dataframe of Experiment Runs.

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

Gets experiment if one exists with this experiment_name in Vertex AI Experiments.

Otherwise creates this experiment.
