Endpoint(
    endpoint_name: str,
    project: Optional[str] = None,
    location: Optional[str] = None,
    credentials: Optional[google.auth.credentials.Credentials] = None,
)

Retrieves an endpoint resource.

Parameters

Name	Description
endpoint_name	str Required. A fully-qualified endpoint resource name or endpoint ID. Example: "projects/123/locations/us-central1/endpoints/456" or "456" when project and location are initialized or passed.
project	str Optional. Project to retrieve endpoint from. If not set, project set in aiplatform.init will be used.
location	str Optional. Location to retrieve endpoint from. If not set, location set in aiplatform.init will be used.
credentials	auth_credentials.Credentials Optional. Custom credentials to use to upload this model. Overrides credentials set in aiplatform.init.

Inheritance

builtins.object > google.cloud.aiplatform.base.VertexAiResourceNoun > builtins.object > google.cloud.aiplatform.base.FutureManager > google.cloud.aiplatform.base.VertexAiResourceNounWithFutureManager > Endpoint

Properties

network

The full name of the Google Compute Engine network to which this Endpoint 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 Endpoint is not peered with any network.

traffic_split

A map from a DeployedModel's ID to the percentage of this Endpoint's traffic that should be forwarded to that DeployedModel.

If a DeployedModel's ID is not listed in this map, then it receives no traffic.

The traffic percentage values must add up to 100, or map must be empty if the Endpoint is to not accept any traffic at a moment.

Methods

create

create(
    display_name: str,
    description: Optional[str] = None,
    labels: Optional[Dict[str, str]] = None,
    metadata: Optional[Sequence[Tuple[str, str]]] = (),
    project: Optional[str] = None,
    location: Optional[str] = None,
    credentials: Optional[google.auth.credentials.Credentials] = None,
    encryption_spec_key_name: Optional[str] = None,
    sync=True,
)

description	str Optional. The description of the Endpoint.
labels	Dict[str, str] Optional. The labels with user-defined metadata to organize your Endpoints. Label keys and values can be no longer than 64 characters (Unicode codepoints), can only contain lowercase letters, numeric characters, underscores and dashes. International characters are allowed. See https://goo.gl/xmQnxf for more information and examples of labels.
metadata	Sequence[Tuple[str, str]] Optional. Strings which should be sent along with the request as metadata.
project	str Required. Project to retrieve endpoint from. If not set, project set in aiplatform.init will be used.
location	str Required. Location to retrieve endpoint from. If not set, location set in aiplatform.init will be used.
credentials	auth_credentials.Credentials Optional. Custom credentials to use to upload this model. Overrides credentials set in aiplatform.init.
encryption_spec_key_name	Optional[str] Optional. The Cloud KMS resource identifier of the customer managed encryption key used to protect the model. Has the form: projects/my-project/locations/my-region/keyRings/my-kr/cryptoKeys/my-key. The key needs to be in the same region as where the compute resource is created. If set, this Endpoint and all sub-resources of this Endpoint will be secured by this key. Overrides encryption_spec_key_name set in aiplatform.init.
sync	bool Whether to execute this method synchronously. If False, this method will be executed in concurrent Future and any downstream object will be immediately returned and synced when the Future has completed.

Returns

Type	Description
endpoint (endpoint.Endpoint)	Created endpoint.

delete

delete(force: bool = False, sync: bool = True)

Deletes this Vertex AI Endpoint resource. If force is set to True, all models on this Endpoint will be undeployed prior to deletion.

Parameters

Name	Description
force	bool Required. If force is set to True, all deployed models on this Endpoint will be undeployed first. Default is False.
sync	bool Whether to execute this method synchronously. If False, this method will be executed in concurrent Future and any downstream object will be immediately returned and synced when the Future has completed.

Exceptions

Type	Description
FailedPrecondition	If models are deployed on this Endpoint and force = False.

deploy

deploy(
    model: google.cloud.aiplatform.models.Model,
    deployed_model_display_name: Optional[str] = None,
    traffic_percentage: int = 0,
    traffic_split: Optional[Dict[str, int]] = None,
    machine_type: Optional[str] = None,

        google.cloud.aiplatform_v1.types.explanation_metadata.ExplanationMetadata
    ] = None,
    explanation_parameters: Optional[
        google.cloud.aiplatform_v1.types.explanation.ExplanationParameters
    ] = None,
    metadata: Optional[Sequence[Tuple[str, str]]] = (),
    sync=True,
)

Deploys a Model to the Endpoint.

Parameters

Name	Description
deployed_model_display_name	str Optional. The display name of the DeployedModel. If not provided upon creation, the Model's display_name is used.
traffic_percentage	int Optional. Desired traffic to newly deployed model. Defaults to 0 if there are pre-existing deployed models. Defaults to 100 if there are no pre-existing deployed models. Negative values should not be provided. Traffic of previously deployed models at the endpoint will be scaled down to accommodate new deployed model's traffic. Should not be provided if traffic_split is provided.
traffic_split	Dict[str, int] Optional. A map from a DeployedModel's ID to the percentage of this Endpoint's traffic that should be forwarded to that DeployedModel. If a DeployedModel's ID is not listed in this map, then it receives no traffic. The traffic percentage values must add up to 100, or map must be empty if the Endpoint is to not accept any traffic at the moment. Key for model being deployed is "0". Should not be provided if traffic_percentage is provided.
machine_type	str Optional. The type of machine. Not specifying machine type will result in model to be deployed with automatic resources.
min_replica_count	int Optional. The minimum number of machine replicas this deployed model will be always deployed on. If traffic against it increases, it may dynamically be deployed onto more replicas, and as traffic decreases, some of these extra replicas may be freed.
max_replica_count	int Optional. The maximum number of replicas this deployed model may be deployed on when the traffic against it increases. If requested value is too large, the deployment will error, but if deployment succeeds then the ability to scale the model to that many replicas is guaranteed (barring service outages). If traffic against the deployed model increases beyond what its replicas at maximum may handle, a portion of the traffic will be dropped. If this value is not provided, the larger value of min_replica_count or 1 will be used. If value provided is smaller than min_replica_count, it will automatically be increased to be min_replica_count.
accelerator_type	str Optional. Hardware accelerator type. Must also set accelerator_count if used. One of ACCELERATOR_TYPE_UNSPECIFIED, NVIDIA_TESLA_K80, NVIDIA_TESLA_P100, NVIDIA_TESLA_V100, NVIDIA_TESLA_P4, NVIDIA_TESLA_T4
accelerator_count	int Optional. The number of accelerators to attach to a worker replica.
service_account	str The service account that the DeployedModel's container runs as. Specify the email address of the service account. If this service account is not specified, the container runs as a service account that doesn't have access to the resource project. Users deploying the Model must have the iam.serviceAccounts.actAs permission on this service account.
explanation_metadata	explain.ExplanationMetadata Optional. Metadata describing the Model's input and output for explanation. Both explanation_metadata and explanation_parameters must be passed together when used. For more details, see Ref docs <http://tinyurl.com/1igh60kt>
explanation_parameters	explain.ExplanationParameters Optional. Parameters to configure explaining for Model's predictions. For more details, see Ref docs <http://tinyurl.com/1an4zake>
metadata	Sequence[Tuple[str, str]] Optional. Strings which should be sent along with the request as metadata.
model	aiplatform.Model Required. Model to be deployed.
sync	bool Whether to execute this method synchronously. If False, this method will be executed in concurrent Future and any downstream object will be immediately returned and synced when the Future has completed.

explain
