data |
array
Optional. Data for populating the Message object. |
↳ name |
string
The resource name of the Model. |
↳ version_id |

Output only. Immutable. The version ID of the model. A new version is committed when a new model version is uploaded or trained under an existing model id. It is an auto-incrementing decimal number in string representation. |
↳ version_aliases |
array
User provided version aliases so that a model version can be referenced via alias (i.e. |
↳ version_create_time |
Google\Protobuf\Timestamp
Output only. Timestamp when this version was created. |
↳ version_update_time |
Google\Protobuf\Timestamp
Output only. Timestamp when this version was most recently updated. |
↳ display_name |
string
Required. The display name of the Model. The name can be up to 128 characters long and can consist of any UTF-8 characters. |
↳ description |
string
The description of the Model. |

↳ predict_schemata |
Google\Cloud\AIPlatform\V1\PredictSchemata
The schemata that describe formats of the Model's predictions and explanations as given and returned via PredictionService.Predict and PredictionService.Explain. |
↳ metadata_schema_uri |
string
Immutable. Points to a YAML file stored on Google Cloud Storage describing additional information about the Model, that is specific to it. Unset if the Model does not have any additional information. The schema is defined as an OpenAPI 3.0.2 Schema Object. AutoML Models always have this field populated by Vertex AI, if no additional metadata is needed, this field is set to an empty string. Note: The URI given on output will be immutable and probably different, including the URI scheme, than the one given on input. The output URI will point to a location where the user only has a read access. |
↳ metadata |
Google\Protobuf\Value
Immutable. An additional information about the Model; the schema of the metadata can be found in metadata_schema. Unset if the Model does not have any additional information. |
↳ supported_export_formats |

getSupportedDeploymentResourcesTypes
Output only. When this Model is deployed, its prediction resources are
described by the prediction_resources
field of the
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 and does not support
online predictions
(PredictionService.Predict
or
PredictionService.Explain).
Such a Model can serve predictions by using a BatchPredictionJob, if it has at least one entry each in supported_input_storage_formats and supported_output_storage_formats.

getSupportedInputStorageFormats
Output only. The formats this Model supports in BatchPredictionJob.input_config.
If 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.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.tf-record
The TFRecord format, where each instance is a single record in tfrecord syntax. Uses GcsSource.tf-record-gzip
Similar totf-record
, but the file is gzipped. Uses GcsSource.bigquery
Each instance is a single row in BigQuery. Uses BigQuerySource.file-list
Each line of the file is the location of an instance to process, usesgcs_source
field of the InputConfig object. If this Model doesn't support any of these formats it means it cannot be used with a BatchPredictionJob. However, if it has supported_deployment_resources_types, it could serve online predictions by using PredictionService.Predict or PredictionService.Explain.

getSupportedOutputStorageFormats
Output only. The formats this Model supports in BatchPredictionJob.output_config.
If both PredictSchemata.instance_schema_uri and 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.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.bigquery
Each prediction is a single row in a BigQuery table, uses BigQueryDestination . If this Model doesn't support any of these formats it means it cannot be used with a BatchPredictionJob. However, if it has supported_deployment_resources_types, it could serve online predictions by using PredictionService.Predict or PredictionService.Explain.
