class google.cloud.bigquery.model.Model(model_ref)[source]#

Bases: object

Model represents a machine learning model resource.

See https://cloud.google.com/bigquery/docs/reference/rest/v2/models

Parameters

model_ref (Union[ ModelReference, str, ]) – A pointer to a model. If model_ref is a string, it must included a project ID, dataset ID, and model ID, each separated by ..

property created#

Read-only.

Type

Union[datetime.datetime, None]

property dataset_id#

ID of dataset containing the model.

Type

str

property description#

Description of the model (defaults to None).

Type

Union[str, None]

property etag#

ETag for the model resource (None until set from the server).

Read-only.

Type

str

property expires#

The datetime when this model expires. If not present, the model will persist indefinitely. Expired models will be deleted and their storage reclaimed.

Type

Union[datetime.datetime, None]

property feature_columns#

Input feature columns that were used to train this model.

Read-only.

An iterable of StandardSqlField.

Type

classmethod from_api_repr(resource)[source]#

Factory: construct a model resource given its API representation

Parameters

resource (Dict[str, object]) – Model resource representation from the API

Returns

Model parsed from resource.

Return type

google.cloud.bigquery.model.Model

Read-only.

An iterable of StandardSqlField.

Type

Sequence[google.cloud.bigquery_v2.types.StandardSqlField]

property labels#

Labels for the table.

This method always returns a dict. To change a model’s labels, modify the dict, then call Client.update_model. To delete a label, set its value to None before updating.

Type

Dict[str, str]

Read-only.

Type

str

property model_id#

The model ID.

Type

str

property model_type#

Type of the model resource.

Read-only.

The value is one of elements of the ModelType enumeration.

Type
