google.cloud.bigquery.model.Model

class google.cloud.bigquery.model.Model(model_ref: Optional[Union[google.cloud.bigquery.model.ModelReference, str]])[source]

Model represents a machine learning model resource.

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

Parameters

model_ref – 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 ..

__init__(model_ref: Optional[Union[google.cloud.bigquery.model.ModelReference, str]])[source]

Initialize self. See help(type(self)) for accurate signature.

Methods

__init__(model_ref)

Initialize self.

property best_trial_id: Optional[int]

The best trial_id across all training runs.

Deprecated since version This: property is deprecated!

Read-only.

property created: Optional[datetime.datetime]

Datetime at which the model was created (None until set from the server).

Read-only.

property dataset_id: Optional[str]

ID of dataset containing the model.

property description: Optional[str]

Description of the model (defaults to None).

property encryption_configuration: Optional[google.cloud.bigquery.encryption_configuration.EncryptionConfiguration]

Custom encryption configuration for the model.

Custom encryption configuration (e.g., Cloud KMS keys) or None if using default encryption.

See protecting data with Cloud KMS keys in the BigQuery documentation.

property etag: Optional[str]

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

Read-only.

property expires: Optional[datetime.datetime]

The datetime when this model expires.

If not present, the model will persist indefinitely. Expired models will be deleted and their storage reclaimed.

property feature_columns: Sequence[google.cloud.bigquery.standard_sql.StandardSqlField]

Input feature columns that were used to train this model.

Read-only.

property friendly_name: Optional[str]

Title of the table (defaults to None).

classmethod from_api_repr(resource: Dict[str, Any])google.cloud.bigquery.model.Model[source]

Factory: construct a model resource given its API representation

Parameters

resource – Model resource representation from the API

Returns

Model parsed from resource.

property label_columns: Sequence[google.cloud.bigquery.standard_sql.StandardSqlField]

Label columns that were used to train this model.

The output of the model will have a predicted_ prefix to these columns.

Read-only.

property labels: Dict[str, str]

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.

property location: Optional[str]

The geographic location where the model resides.

This value is inherited from the dataset.

Read-only.

property model_id: Optional[str]

The model ID.

property model_type: str

Type of the model resource.

Read-only.

property modified: Optional[datetime.datetime]

Datetime at which the model was last modified (None until set from the server).

Read-only.

property path: Optional[str]

URL path for the model’s APIs.

property project: Optional[str]

Project bound to the model.

property reference: Optional[google.cloud.bigquery.model.ModelReference]

A model reference pointing to this model.

Read-only.

to_api_repr()Dict[str, Any][source]

Construct the API resource representation of this model.

Returns

Model reference represented as an API resource
