ExplanationSpec

public ExplanationSpec ExplanationSpec { get; set; }

The default explanation specification for this Model.

The Model can be used for [requesting explanation][google.cloud.aiplatform.v1.PredictionService.Explain] after being [deployed][google.cloud.aiplatform.v1.EndpointService.DeployModel] if it is populated. The Model can be used for [batch explanation][google.cloud.aiplatform.v1.BatchPredictionJob.generate_explanation] if it is populated.

All fields of the explanation_spec can be overridden by [explanation_spec][google.cloud.aiplatform.v1.DeployedModel.explanation_spec] of [DeployModelRequest.deployed_model][google.cloud.aiplatform.v1.DeployModelRequest.deployed_model], or [explanation_spec][google.cloud.aiplatform.v1.BatchPredictionJob.explanation_spec] of [BatchPredictionJob][google.cloud.aiplatform.v1.BatchPredictionJob].

If the default explanation specification is not set for this Model, this Model can still be used for [requesting explanation][google.cloud.aiplatform.v1.PredictionService.Explain] by setting [explanation_spec][google.cloud.aiplatform.v1.DeployedModel.explanation_spec] of [DeployModelRequest.deployed_model][google.cloud.aiplatform.v1.DeployModelRequest.deployed_model] and for [batch explanation][google.cloud.aiplatform.v1.BatchPredictionJob.generate_explanation] by setting [explanation_spec][google.cloud.aiplatform.v1.BatchPredictionJob.explanation_spec] of [BatchPredictionJob][google.cloud.aiplatform.v1.BatchPredictionJob].

SupportedDeploymentResourcesTypes

public RepeatedField<Model.Types.DeploymentResourcesType> SupportedDeploymentResourcesTypes { get; }

Output only. When this Model is deployed, its prediction resources are described by the prediction_resources field of the [Endpoint.deployed_models][google.cloud.aiplatform.v1.Endpoint.deployed_models] object. Because not all Models support all resource configuration types, the configuration types this Model supports are listed here. If no configuration types are listed, the Model cannot be deployed to an [Endpoint][google.cloud.aiplatform.v1.Endpoint] and does not support online predictions ([PredictionService.Predict][google.cloud.aiplatform.v1.PredictionService.Predict] or [PredictionService.Explain][google.cloud.aiplatform.v1.PredictionService.Explain]). Such a Model can serve predictions by using a [BatchPredictionJob][google.cloud.aiplatform.v1.BatchPredictionJob], if it has at least one entry each in [supported_input_storage_formats][google.cloud.aiplatform.v1.Model.supported_input_storage_formats] and [supported_output_storage_formats][google.cloud.aiplatform.v1.Model.supported_output_storage_formats].

Property Value
TypeDescription

SupportedExportFormats

public RepeatedField<Model.Types.ExportFormat> SupportedExportFormats { get; }

Output only. The formats in which this Model may be exported. If empty, this Model is not available for export.

Property Value
TypeDescription
RepeatedFieldModelTypesExportFormat

SupportedInputStorageFormats

public RepeatedField<string> SupportedInputStorageFormats { get; }

Output only. The formats this Model supports in [BatchPredictionJob.input_config][google.cloud.aiplatform.v1.BatchPredictionJob.input_config]. If [PredictSchemata.instance_schema_uri][google.cloud.aiplatform.v1.PredictSchemata.instance_schema_uri] exists, the instances should be given as per that schema.

The possible formats are:

  • jsonl The JSON Lines format, where each instance is a single line. Uses [GcsSource][google.cloud.aiplatform.v1.BatchPredictionJob.InputConfig.gcs_source].

  • csv The CSV format, where each instance is a single comma-separated line. The first line in the file is the header, containing comma-separated field names. Uses [GcsSource][google.cloud.aiplatform.v1.BatchPredictionJob.InputConfig.gcs_source].

  • tf-record The TFRecord format, where each instance is a single record in tfrecord syntax. Uses [GcsSource][google.cloud.aiplatform.v1.BatchPredictionJob.InputConfig.gcs_source].

  • tf-record-gzip Similar to tf-record, but the file is gzipped. Uses [GcsSource][google.cloud.aiplatform.v1.BatchPredictionJob.InputConfig.gcs_source].

  • bigquery Each instance is a single row in BigQuery. Uses [BigQuerySource][google.cloud.aiplatform.v1.BatchPredictionJob.InputConfig.bigquery_source].

  • file-list Each line of the file is the location of an instance to process, uses gcs_source field of the [InputConfig][google.cloud.aiplatform.v1.BatchPredictionJob.InputConfig] object.

If this Model doesn't support any of these formats it means it cannot be used with a [BatchPredictionJob][google.cloud.aiplatform.v1.BatchPredictionJob]. However, if it has [supported_deployment_resources_types][google.cloud.aiplatform.v1.Model.supported_deployment_resources_types], it could serve online predictions by using [PredictionService.Predict][google.cloud.aiplatform.v1.PredictionService.Predict] or [PredictionService.Explain][google.cloud.aiplatform.v1.PredictionService.Explain].

Property Value
TypeDescription
RepeatedFieldstring

SupportedOutputStorageFormats

public RepeatedField<string> SupportedOutputStorageFormats { get; }

Output only. The formats this Model supports in [BatchPredictionJob.output_config][google.cloud.aiplatform.v1.BatchPredictionJob.output_config]. If both [PredictSchemata.instance_schema_uri][google.cloud.aiplatform.v1.PredictSchemata.instance_schema_uri] and [PredictSchemata.prediction_schema_uri][google.cloud.aiplatform.v1.PredictSchemata.prediction_schema_uri] exist, the predictions are returned together with their instances. In other words, the prediction has the original instance data first, followed by the actual prediction content (as per the schema).

The possible formats are:

  • jsonl The JSON Lines format, where each prediction is a single line. Uses [GcsDestination][google.cloud.aiplatform.v1.BatchPredictionJob.OutputConfig.gcs_destination].

  • csv The CSV format, where each prediction is a single comma-separated line. The first line in the file is the header, containing comma-separated field names. Uses [GcsDestination][google.cloud.aiplatform.v1.BatchPredictionJob.OutputConfig.gcs_destination].

  • bigquery Each prediction is a single row in a BigQuery table, uses [BigQueryDestination][google.cloud.aiplatform.v1.BatchPredictionJob.OutputConfig.bigquery_destination] .

If this Model doesn't support any of these formats it means it cannot be used with a [BatchPredictionJob][google.cloud.aiplatform.v1.BatchPredictionJob]. However, if it has [supported_deployment_resources_types][google.cloud.aiplatform.v1.Model.supported_deployment_resources_types], it could serve online predictions by using [PredictionService.Predict][google.cloud.aiplatform.v1.PredictionService.Predict] or [PredictionService.Explain][google.cloud.aiplatform.v1.PredictionService.Explain].

public Timestamp UpdateTime { get; set; }

Output only. Timestamp when this Model was most recently updated.

Property Value
TypeDescription
Timestamp

VersionAliases

public RepeatedField<string> VersionAliases { get; }

User provided version aliases so that a model version can be referenced via alias (i.e. projects/{project}/locations/{location}/models/{model_id}@{version_alias} instead of auto-generated version id (i.e. projects/{project}/locations/{location}/models/{model_id}@{version_id}). The format is [a-z][a-zA-Z0-9-]{0,126}[a-z0-9] to distinguish from version_id. A default version alias will be created for the first version of the model, and there must be exactly one default version alias for a model.
