) -> typing.Optional[google.cloud.aiplatform.models.Model]

Runs the custom training job.

You can configure a custom training job as a distributed training job by specifying multiple replicas. To define more than one replica, set replica_count to a number greater than one. For example, if you specify 10 for replica_count, then one chief replica is provisioned and nine replicas are created that make up a worker pool. All replicas in the worker pool have the same machine_type, accelerator_type, and accelerator_count. For more information, see Distributed training.

If you train on a Vertex AI dataset, you can use one of the following split configurations:

  • Random split: The random split is also known as mathematical split or fraction split. By default, the percentages of training data used for the training, validation, and test sets are 80, 10, and 10, respectively. If you are using Google Cloud console, you can change the percentages to any values that add up to 100. If you are using the Vertex AI SDK, you use fractions that add up to 1.0. Use the optional training_fraction_split, validation_fraction_split, and test_fraction_split to change the percentages. If the specified fractions total less than 1.0, then Vertex AI specifies the remainder.

  • Data filter split: Assigns input data to training, validation, and test sets. For example, can set training_filter_split to labels.flower=rose, validation_filter_split to labels.flower=daisy,test_filter_split to labels.flower=dahlia. With these settings, data labeled as rose is added to the training set, data labeled as daisy is added to the validation set, and data labeled as dahlia is added to the test set. If you use filter splits, you need to specify all three filters. If you don't want a filter to match any items, set it to the minus sign (-). Data filter splits are supported only for unstructured datasets that contain dataitems.

  • Manual split: The manual split is also known as a predefined split. A manual split assigns input data to training, validation, and test sets based on the value of a provided key. You must specify the predefined_split_column_name to use a manual split. Manual splits are supported only for tabular datasets.

  • Chronological split: The chronological split is also known as a timestamp split. If your data is time-dependent, you can use the timestamp_split_column_name parameter to designate one column as a time column. Vertex AI uses the time column to split your data, with the earliest of the rows used for training, the next rows for validation, and the latest rows for testing. Chronological splits are supported only for tabular Datasets.

Parameters
Name Description
annotation_schema_uri str

Optional. A Cloud Storage URI that points to a YAML file describing an annotation schema. The schema is defined as an OpenAPI 3.0.2 Schema Object. The schema files that can be used are in the following Cloud Storage bucket: gs://google-cloud-aiplatform/schema/dataset/annotation/. The schema you choose must be consistent with the metadata of the Dataset specified by dataset_id. If you use a split method, then only annotations that match this schema and belong to DataItems that are not ignored by the split method are used. The DataItems are used for training, validation, or testing, depending on their role. If you use an annotations filter, then the annotations used for training are filtered using the annotations filter and the annotation_schema_uri.
model_display_name str

Optional. The user-defined name of the model. The name must contain 128 or fewer UTF-8 characters. If not specified, then the 'display_name` of the training job is used.

Optional. When set to true, the newly uploaded model version includes the alias default. Subsequent models produced by a training job that don't have a version specified use the default version. When set to false, the default alias isn't assigned to the model and verion one of the model is always the default. Actions targeting the model version produced by this job need to reference this version by its ID or alias.
model_version_aliases Sequence[str]

Optional. User provided version aliases that can be used instead of an auto-generated ID to reference the model version uploaded by the training job. A default version alias is created for the first version of the model. The format is a-z][a-zA-Z0-9-]{0,126}[a-z0-9]`.
model_version_description str

Optional. The description of the model version that's uploaded by this training job.
base_output_dir str

Optional. The Cloud Storage output directory of the training job. If not provided, a timestamped directory in the staging directory is used.

AIP_CHECKPOINT_DIR: a Cloud Storage URI of a directory used to save checkpoints, such as <base_output_dir>/checkpoints/. AIP_TENSORBOARD_LOG_DIR: a Cloud Storage URI of a directory used to save TensorBoard logs, such as <base_output_dir>/logs/.
service_account str

Optional. A service account used to run the pipeline training job. To submit a pipeline training job using a service account, a user needs to have the iam.serviceAccounts.actAs permission on the service account. For more information, see Requiring permission to attach service accounts to resources.
network str

Optional. The full name of the Compute Engine network to which the job should be peered. For example, projects/12345/global/networks/myVPC. Private services access must already be configured for the network. If left unspecified, the network set by aiplatform.init is used and the pipeline job is not peered with any network.
bigquery_destination str

Optional. When using a BigQuery dataset, this is the BigQuery project location to where the training data is written. A new dataset is created in the specified project with the name dataset_, where the timestamp is in the YYYY_MM_DDThh_mm_ss_sssZ format. All training input data is written into the new dataset that includes three tables: training, validation, and test. - AIP_DATA_FORMAT = "bigquery". - AIP_TRAINING_DATA_URI ="bigquery_destination.dataset_.training" - AIP_VALIDATION_DATA_URI = "bigquery_destination.dataset_.validation" - AIP_TEST_DATA_URI = "bigquery_destination.dataset_*.test"

If replica_count > 1 the remainder will be provisioned as a worker replica pool. ie: replica_count = 10 will result in 1 chief and 9 workers All replicas have same machine_type, accelerator_type, and accelerator_count

If training on a Vertex AI dataset, you can use one of the following split configurations: Data fraction splits: Any of training_fraction_split, validation_fraction_split and test_fraction_split may optionally be provided, they must sum to up to 1. If the provided ones sum to less than 1, the remainder is assigned to sets as decided by Vertex AI. If none of the fractions are set, by default roughly 80% of data will be used for training, 10% for validation, and 10% for test.

Data filter splits:
Assigns input data to training, validation, and test sets
based on the given filters, data pieces not matched by any
filter are ignored. Currently only supported for Datasets
containing DataItems.
If any of the filters in this message are to match nothing, then
they can be set as '-' (the minus sign).
If using filter splits, all of `training_filter_split`, `validation_filter_split` and
`test_filter_split` must be provided.
Supported only for unstructured Datasets.

Predefined splits:
Assigns input data to training, validation, and test sets based on the value of a provided key.
If using predefined splits, `predefined_split_column_name` must be provided.
Supported only for tabular Datasets.

Timestamp splits:
Assigns input data to training, validation, and test sets
based on a provided timestamps. The youngest data pieces are
assigned to training set, next to validation set, and the oldest
to the test set.
Supported only for tabular Datasets.
