* **search_algorithm** ([*str*](https://python.readthedocs.io/en/latest/library/stdtypes.html#str)) – The search algorithm specified for the Study.
Accepts one of the following:

> None - If you do not specify an algorithm, your job uses the default
> Vertex AI algorithm. The default algorithm applies Bayesian optimization
> to arrive at the optimal solution with a more effective search over the
> parameter space.

> ’grid’ - A simple grid search within the feasible space. This option is
> particularly useful if you want to specify a quantity of trials that is greater
> than the number of points in the feasible space. In such cases, if you do
> not specify a grid search, the Vertex AI default algorithm may generate
> duplicate suggestions. To use grid search, all parameter specs must be of
> type IntegerParameterSpec, CategoricalParameterSpec, or DiscreteParameterSpec.

> ’random’ - A simple random search within the feasible space.

Runs the AutoML Image training job and returns a model.

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.

• Parameters

  • dataset (datasets.ImageDataset) – Required. The dataset within the same Project from which data will be used to train the Model. The Dataset must use schema compatible with Model being trained, and what is compatible should be described in the used TrainingPipeline’s [training_task_definition] [google.cloud.aiplatform.v1beta1.TrainingPipeline.training_task_definition]. For tabular Datasets, all their data is exported to training, to pick and choose from.

  • training_fraction_split (float) – Optional. The fraction of the input data that is to be used to train the Model. This is ignored if Dataset is not provided.

  • validation_fraction_split (float) – Optional. The fraction of the input data that is to be used to validate the Model. This is ignored if Dataset is not provided.

  • test_fraction_split (float) – Optional. The fraction of the input data that is to be used to evaluate the Model. This is ignored if Dataset is not provided.

  • training_filter_split (str) – Optional. A filter on DataItems of the Dataset. DataItems that match this filter are used to train the Model. A filter with same syntax as the one used in DatasetService.ListDataItems may be used. If a single DataItem is matched by more than one of the FilterSplit filters, then it is assigned to the first set that applies to it in the training, validation, test order. This is ignored if Dataset is not provided.

  • validation_filter_split (str) – Optional. A filter on DataItems of the Dataset. DataItems that match this filter are used to validate the Model. A filter with same syntax as the one used in DatasetService.ListDataItems may be used. If a single DataItem is matched by more than one of the FilterSplit filters, then it is assigned to the first set that applies to it in the training, validation, test order. This is ignored if Dataset is not provided.

  • test_filter_split (str) – Optional. A filter on DataItems of the Dataset. DataItems that match this filter are used to test the Model. A filter with same syntax as the one used in DatasetService.ListDataItems may be used. If a single DataItem is matched by more than one of the FilterSplit filters, then it is assigned to the first set that applies to it in the training, validation, test order. This is ignored if Dataset is not provided.

  • budget_milli_node_hours (int) – Optional. The train budget of creating this Model, expressed in milli node hours i.e. 1,000 value in this field means 1 node hour. Defaults by prediction_type: classification - For Cloud models the budget must be: 8,000 - 800,000 milli node hours (inclusive). The default value is 192,000 which represents one day in wall time, assuming 8 nodes are used. object_detection - For Cloud models the budget must be: 20,000 - 900,000 milli node hours (inclusive). The default value is 216,000 which represents one day in wall time, assuming 9 nodes are used. The training cost of the model will not exceed this budget. The final cost will be attempted to be close to the budget, though may end up being (even) noticeably smaller - at the backend’s discretion. This especially may happen when further model training ceases to provide any improvements. If the budget is set to a value known to be insufficient to train a Model for the given training set, the training won’t be attempted and will error.

  • model_display_name (str) – Optional. The display name of the managed Vertex AI Model. The name can be up to 128 characters long and can be consist of any UTF-8 characters. If not provided upon creation, the job’s display_name is used.

  • model_labels (Dict[str, *[str](https://python.readthedocs.io/en/latest/library/stdtypes.html#str)]*) – Optional. The labels with user-defined metadata to organize your Models. 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.

  • model_id (str) – Optional. The ID to use for the Model produced by this job, which will become the final component of the model resource name. This value may be up to 63 characters, and valid characters are [a-z0-9_-]. The first character cannot be a number or hyphen.

  • parent_model (str) – Optional. The resource name or model ID of an existing model. The new model uploaded by this job will be a version of parent_model. Only set this field when training a new version of an existing model.

  • is_default_version (bool) – Optional. When set to True, the newly uploaded model version will automatically have alias “default” included. Subsequent uses of the model produced by this job without a version specified will use this “default” version. When set to False, the “default” alias will not be moved. Actions targeting the model version produced by this job will need to specifically reference this version by ID or alias. New model uploads, i.e. version 1, will always be “default” aliased.

  • model_version_aliases (Sequence[str]) – Optional. User provided version aliases so that the model version uploaded by this job can be referenced via alias instead of auto-generated version ID. A default version alias will be 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 being uploaded by this job.

  • disable_early_stopping – bool = False Required. If true, the entire budget is used. This disables the early stopping feature. By default, the early stopping feature is enabled, which means that training might stop before the entire training budget has been used, if further training does no longer brings significant improvement to the model.

  • sync – bool = True 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.

  • create_request_timeout (float) – Optional. The timeout for the create request in seconds.

Bases: google.cloud.aiplatform.training_jobs._TrainingJob

Constructs a AutoML Tabular Training Job.

Example usage:

job = training_jobs.AutoMLTabularTrainingJob(

display_name=”my_display_name”,
optimization_prediction_type=”classification”,
optimization_objective=”minimize-log-loss”,
column_specs={“column_1”: “auto”, “column_2”: “numeric”},
labels={‘key’: ‘value’},

)

• Parameters

  • display_name (str) – Required. The user-defined name of this TrainingPipeline.

  • optimization_prediction_type (str) – The type of prediction the Model is to produce. “classification” - Predict one out of multiple target values is picked for each row. “regression” - Predict a value based on its relation to other values. This type is available only to columns that contain semantically numeric values, i.e. integers or floating point number, even if stored as e.g. strings.

  • optimization_objective (str) – Optional. Objective function the Model is to be optimized towards. The training task creates a Model that maximizes/minimizes the value of the objective function over the validation set.

    The supported optimization objectives depend on the prediction type, and in the case of classification also the number of distinct values in the target column (two distint values -> binary, 3 or more distinct values -> multi class). If the field is not set, the default objective function is used.

    Classification (binary): “maximize-au-roc” (default) - Maximize the area under the receiver

    operating characteristic (ROC) curve.

    ”minimize-log-loss” - Minimize log loss. “maximize-au-prc” - Maximize the area under the precision-recall curve. “maximize-precision-at-recall” - Maximize precision for a specified

    recall value.

    ”maximize-recall-at-precision” - Maximize recall for a specified

    precision value.

    Classification (multi class): “minimize-log-loss” (default) - Minimize log loss.

    Regression: “minimize-rmse” (default) - Minimize root-mean-squared error (RMSE). “minimize-mae” - Minimize mean-absolute error (MAE). “minimize-rmsle” - Minimize root-mean-squared log error (RMSLE).

  • column_specs (Dict[str, *[str](https://python.readthedocs.io/en/latest/library/stdtypes.html#str)]*) – Optional. Alternative to column_transformations where the keys of the dict are column names and their respective values are one of AutoMLTabularTrainingJob.column_data_types. When creating transformation for BigQuery Struct column, the column should be flattened using “.” as the delimiter. Only columns with no child should have a transformation. If an input column has no transformations on it, such a column is ignored by the training, except for the targetColumn, which should have no transformations defined on. Only one of column_transformations or column_specs should be passed. If none of column_transformations or column_specs is passed, the local credentials being used will try setting column_specs to “auto”. To do this, the local credentials require read access to the GCS or BigQuery training data source.

  • column_transformations (List[Dict[str, **Dict[str, *[str](https://python.readthedocs.io/en/latest/library/stdtypes.html#str)]]]*) – Optional. Transformations to apply to the input columns (i.e. columns other than the targetColumn). Each transformation may produce multiple result values from the column’s value, and all are used for training. When creating transformation for BigQuery Struct column, the column should be flattened using “.” as the delimiter. Only columns with no child should have a transformation. If an input column has no transformations on it, such a column is ignored by the training, except for the targetColumn, which should have no transformations defined on. Only one of column_transformations or column_specs should be passed. Consider using column_specs as column_transformations will be deprecated eventually. If none of column_transformations or column_specs is passed, the local credentials being used will try setting column_transformations to “auto”. To do this, the local credentials require read access to the GCS or BigQuery training data source.

  • optimization_objective_recall_value (float) – Optional. Required when maximize-precision-at-recall optimizationObjective was picked, represents the recall value at which the optimization is done.

    The minimum value is 0 and the maximum is 1.0.

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 TrainingPipeline will be secured by this key.

    Note: Model trained by this TrainingPipeline is also secured by this key if model_to_upload is not set separately.

    Overrides encryption_spec_key_name set in aiplatform.init.

  • model_encryption_spec_key_name (Optional[str]) – Optional. The Cloud KMS resource identifier of the customer managed encryption key used to protect the model.

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.

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.

• Parameters

  • dataset (datasets.TabularDataset) – Required. The dataset within the same Project from which data will be used to train the Model. The Dataset must use schema compatible with Model being trained, and what is compatible should be described in the used TrainingPipeline’s [training_task_definition] [google.cloud.aiplatform.v1beta1.TrainingPipeline.training_task_definition]. For tabular Datasets, all their data is exported to training, to pick and choose from.

  • target_column (str) – Required. The name of the column values of which the Model is to predict.

  • training_fraction_split (float) – Optional. The fraction of the input data that is to be used to train the Model. This is ignored if Dataset is not provided.

  • validation_fraction_split (float) – Optional. The fraction of the input data that is to be used to validate the Model. This is ignored if Dataset is not provided.

  • test_fraction_split (float) – Optional. The fraction of the input data that is to be used to evaluate the Model. This is ignored if Dataset is not provided.

  • predefined_split_column_name (str) – Optional. The key is a name of one of the Dataset’s data columns. The value of the key (either the label’s value or value in the column) must be one of {training, validation, test}, and it defines to which set the given piece of data is assigned. If for a piece of data the key is not present or has an invalid value, that piece is ignored by the pipeline.

    Supported only for tabular and time series Datasets.

  • timestamp_split_column_name (str) – Optional. The key is a name of one of the Dataset’s data columns. The value of the key values of the key (the values in the column) must be in RFC 3339 date-time format, where time-offset = “Z” (e.g. 1985-04-12T23:20:50.52Z). If for a piece of data the key is not present or has an invalid value, that piece is ignored by the pipeline. Supported only for tabular and time series Datasets. This parameter must be used with training_fraction_split, validation_fraction_split, and test_fraction_split.

  • weight_column (str) – Optional. Name of the column that should be used as the weight column. Higher values in this column give more importance to the row during Model training. The column must have numeric values between 0 and 10000 inclusively, and 0 value means that the row is ignored. If the weight column field is not set, then all rows are assumed to have equal weight of 1.

  • budget_milli_node_hours (int) – Optional. The train budget of creating this Model, expressed in milli node hours i.e. 1,000 value in this field means 1 node hour. The training cost of the model will not exceed this budget. The final cost will be attempted to be close to the budget, though may end up being (even) noticeably smaller - at the backend’s discretion. This especially may happen when further model training ceases to provide any improvements. If the budget is set to a value known to be insufficient to train a Model for the given training set, the training won’t be attempted and will error. The minimum value is 1000 and the maximum is 72000.

  • model_display_name (str) – Optional. If the script produces a managed Vertex AI Model. The display name of the Model. The name can be up to 128 characters long and can be consist of any UTF-8 characters.

    If not provided upon creation, the job’s display_name is used.

  • model_labels (Dict[str, *[str](https://python.readthedocs.io/en/latest/library/stdtypes.html#str)]*) – Optional. The labels with user-defined metadata to organize your Models. 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.

  • model_id (str) – Optional. The ID to use for the Model produced by this job, which will become the final component of the model resource name. This value may be up to 63 characters, and valid characters are [a-z0-9_-]. The first character cannot be a number or hyphen.

  • parent_model (str) – Optional. The resource name or model ID of an existing model. The new model uploaded by this job will be a version of parent_model.

    Only set this field when training a new version of an existing model.

  • is_default_version (bool) – Optional. When set to True, the newly uploaded model version will automatically have alias “default” included. Subsequent uses of the model produced by this job without a version specified will use this “default” version.

    When set to False, the “default” alias will not be moved. Actions targeting the model version produced by this job will need to specifically reference this version by ID or alias.

    New model uploads, i.e. version 1, will always be “default” aliased.

  • model_version_aliases (Sequence[str]) – Optional. User provided version aliases so that the model version uploaded by this job can be referenced via alias instead of auto-generated version ID. A default version alias will be 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 being uploaded by this job.

  • disable_early_stopping (bool) – Required. If true, the entire budget is used. This disables the early stopping feature. By default, the early stopping feature is enabled, which means that training might stop before the entire training budget has been used, if further training does no longer brings significant improvement to the model.

  • export_evaluated_data_items (bool) – Whether to export the test set predictions to a BigQuery table. If False, then the export is not performed.

  • export_evaluated_data_items_bigquery_destination_uri (string) – Optional. URI of desired destination BigQuery table for exported test set predictions.

    Expected format: bq://<project_id>:<dataset_id>:<table>

    Applies only if [export_evaluated_data_items] is True.

  • export_evaluated_data_items_override_destination (bool) – Whether to override the contents of [export_evaluated_data_items_bigquery_destination_uri], if the table exists, for exported test set predictions. If False, and the table exists, then the training job will fail.

    Applies only if [export_evaluated_data_items] is True and [export_evaluated_data_items_bigquery_destination_uri] is specified.

  • additional_experiments (List[str]) – Optional. Additional experiment flags for the automl tables training.

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

Data fraction splits:
`training_fraction_split`, and `test_fraction_split` may optionally
be provided, they must sum to up to 1. If none of the fractions are set,
by default roughly 80% of data will be used for training, and 20% 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.

• Parameters

  • dataset (datasets.VideoDataset) – Required. The dataset within the same Project from which data will be used to train the Model. The Dataset must use schema compatible with Model being trained, and what is compatible should be described in the used TrainingPipeline’s [training_task_definition] [google.cloud.aiplatform.v1beta1.TrainingPipeline.training_task_definition]. For tabular Datasets, all their data is exported to training, to pick and choose from.

  • training_fraction_split (float) – Optional. The fraction of the input data that is to be used to train the Model. This is ignored if Dataset is not provided.

  • test_fraction_split (float) – Optional. The fraction of the input data that is to be used to evaluate the Model. This is ignored if Dataset is not provided.

  • training_filter_split (str) – Optional. A filter on DataItems of the Dataset. DataItems that match this filter are used to train the Model. A filter with same syntax as the one used in DatasetService.ListDataItems may be used.

This is ignored if Dataset is not provided.

  • test_filter_split (str) – Optional. A filter on DataItems of the Dataset. DataItems that match this filter are used to test the Model. A filter with same syntax as the one used in DatasetService.ListDataItems may be used. If a single DataItem is matched by more than one of the FilterSplit filters, then it is assigned to the first set that applies to it in the training, validation, test order. This is ignored if Dataset is not provided.

Create a batch prediction job.

• Parameters

  • job_display_name (str) – Required. The user-defined name of the BatchPredictionJob. The name can be up to 128 characters long and can be consist of any UTF-8 characters.

  • model_name (Union[str, **aiplatform.Model]) – Required. A fully-qualified model resource name or model ID. Example: “projects/123/locations/us-central1/models/456” or “456” when project and location are initialized or passed. May optionally contain a version ID or alias in {model_name}@{version} form.

    Or an instance of aiplatform.Model.

  • instances_format (str) – Required. The format in which instances are provided. Must be one of the formats listed in Model.supported_input_storage_formats. Default is “jsonl” when using gcs_source. If a bigquery_source is provided, this is overridden to “bigquery”.

  • predictions_format (str) – Required. The format in which Vertex AI outputs the predictions, must be one of the formats specified in Model.supported_output_storage_formats. Default is “jsonl” when using gcs_destination_prefix. If a bigquery_destination_prefix is provided, this is overridden to “bigquery”.

  • gcs_source (Optional[Sequence[str]]) – Google Cloud Storage URI(-s) to your instances to run batch prediction on. They must match instances_format.

  • bigquery_source (Optional[str]) – BigQuery URI to a table, up to 2000 characters long. For example: bq://projectId.bqDatasetId.bqTableId

  • gcs_destination_prefix (Optional[str]) – The Google Cloud Storage location of the directory where the output is to be written to. In the given directory a new directory is created. Its name is prediction-<model-display-name>-<job-create-time>, where timestamp is in YYYY-MM-DDThh:mm:ss.sssZ ISO-8601 format. Inside of it files predictions_0001.<extension>, predictions_0002.<extension>, …, predictions_N.<extension> are created where <extension> depends on chosen predictions_format, and N may equal 0001 and depends on the total number of successfully predicted instances. If the Model has both instance and prediction schemata defined then each such file contains predictions as per the predictions_format. If prediction for any instance failed (partially or completely), then an additional errors_0001.<extension>, errors_0002.<extension>,…, errors_N.<extension> files are created (N depends on total number of failed predictions). These files contain the failed instances, as per their schema, followed by an additional error field which as value has \google.rpc.Status<Status>\__ containing only code and message fields.

  • bigquery_destination_prefix (Optional[str]) – The BigQuery project or dataset location where the output is to be written to. If project is provided, a new dataset is created with name prediction_<model-display-name>_<job-create-time> where is made BigQuery-dataset-name compatible (for example, most special characters become underscores), and timestamp is in YYYY_MM_DDThh_mm_ss_sssZ “based on ISO-8601” format. In the dataset two tables will be created, predictions, and errors. If the Model has both [instance][google.cloud.aiplatform.v1.PredictSchemata.instance_schema_uri] and [prediction][google.cloud.aiplatform.v1.PredictSchemata.parameters_schema_uri] schemata defined then the tables have columns as follows: The predictions table contains instances for which the prediction succeeded, it has columns as per a concatenation of the Model’s instance and prediction schemata. The errors table contains rows for which the prediction has failed, it has instance columns, as per the instance schema, followed by a single “errors” column, which as values has [google.rpc.Status][google.rpc.Status] represented as a STRUCT, and containing only code and message.

  • model_parameters (Optional[Dict]) – The parameters that govern the predictions. The schema of the parameters may be specified via the Model’s parameters_schema_uri.

  • generate_explanation (bool) – Optional. Generate explanation along with the batch prediction results. This will cause the batch prediction output to include explanations based on the prediction_format:

    * bigquery: output includes a column named explanation. The value
    
    is a struct that conforms to the [aiplatform.gapic.Explanation] object.
    

>     * jsonl: The JSON objects on each line include an additional entry

>     keyed explanation. The value of the entry is a JSON object that
>     conforms to the [aiplatform.gapic.Explanation] object.


>     * csv: Generating explanations for CSV format is not supported.



* **explanation_metadata** (*aiplatform.explain.ExplanationMetadata*) – Optional. Explanation metadata configuration for this BatchPredictionJob.
Can be specified only if generate_explanation is set to True.

This value overrides the value of Model.explanation_metadata.
All fields of explanation_metadata are optional in the request. If
a field of the explanation_metadata object is not populated, the
corresponding field of the Model.explanation_metadata object is inherited.
For more details, see Ref docs <http://tinyurl.com/1igh60kt>



* **explanation_parameters** (*aiplatform.explain.ExplanationParameters*) – Optional. Parameters to configure explaining for Model’s predictions.
Can be specified only if generate_explanation is set to True.

* **labels** (*Dict**[*[*str*](https://python.readthedocs.io/en/latest/library/stdtypes.html#str)*, *[*str*](https://python.readthedocs.io/en/latest/library/stdtypes.html#str)*]*) – Optional. The labels with user-defined metadata to organize your
BatchPredictionJobs. 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](https://goo.gl/xmQnxf)

* **credentials** (*Optional**[**auth_credentials.Credentials**]*) – Custom credentials to use to create this batch prediction
job. Overrides credentials set in aiplatform.init.


* **encryption_spec_key_name** (*Optional**[*[*str*](https://python.readthedocs.io/en/latest/library/stdtypes.html#str)*]*) – Optional. The Cloud KMS resource identifier of the customer
managed encryption key used to protect the job. 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 this is set, then all
resources created by the BatchPredictionJob will
be encrypted with the provided encryption key.

Overrides encryption_spec_key_name set in aiplatform.init.



* **sync** ([*bool*](https://python.readthedocs.io/en/latest/library/functions.html#bool)) – Whether to execute this method synchronously. If False, this method

* **batch_size** ([*int*](https://python.readthedocs.io/en/latest/library/functions.html#int)) – Optional. The number of the records (e.g. instances) of the operation given in each batch
to a machine replica. Machine type, and size of a single record should be considered
when setting this parameter, higher value speeds up the batch operation’s execution,
but too high value will result in a whole batch not fitting in a machine’s memory,
and the whole operation will fail.
The default value is 64.


* **model_monitoring_objective_config** (*aiplatform.model_monitoring.ObjectiveConfig*) – Optional. The objective config for model monitoring. Passing this parameter enables
monitoring on the model associated with this batch prediction job.


* **model_monitoring_alert_config** (*aiplatform.model_monitoring.EmailAlertConfig*) – Optional. Configures how model monitoring alerts are sent to the user. Right now
only email alert is supported.


* **analysis_instance_schema_uri** ([*str*](https://python.readthedocs.io/en/latest/library/stdtypes.html#str)) – Optional. Only applicable if model_monitoring_objective_config is also passed.
This parameter specifies the YAML schema file uri describing the format of a single
instance that you want Tensorflow Data Validation (TFDV) to
analyze. If this field is empty, all the feature data types are
inferred from predict_instance_schema_uri, meaning that TFDV
will use the data in the exact format as prediction request/response.
If there are any data type differences between predict instance
and TFDV instance, this field can be used to override the schema.
For models trained with Vertex AI, this field must be set as all the
fields in predict instance formatted as string.


* **service_account** ([*str*](https://python.readthedocs.io/en/latest/library/stdtypes.html#str)) – Optional. Specifies the service account for workload run-as account.
Users submitting jobs must have act-as permission on this run-as account.

  • predictions_format (str) – Required. The format in which Vertex AI outputs the predictions, must be one of the formats specified in Model.supported_output_storage_formats. Default is “jsonl” when using gcs_destination_prefix. If a bigquery_destination_prefix is provided, this is overridden to “bigquery”.

  • gcs_source (Optional[Sequence[str]]) – Google Cloud Storage URI(-s) to your instances to run batch prediction on. They must match instances_format.

  • bigquery_source (Optional[str]) – BigQuery URI to a table, up to 2000 characters long. For example: bq://projectId.bqDatasetId.bqTableId

  • gcs_destination_prefix (Optional[str]) – The Google Cloud Storage location of the directory where the output is to be written to. In the given directory a new directory is created. Its name is prediction-<model-display-name>-<job-create-time>, where timestamp is in YYYY-MM-DDThh:mm:ss.sssZ ISO-8601 format. Inside of it files predictions_0001.<extension>, predictions_0002.<extension>, …, predictions_N.<extension> are created where <extension> depends on chosen predictions_format, and N may equal 0001 and depends on the total number of successfully predicted instances. If the Model has both instance and prediction schemata defined then each such file contains predictions as per the predictions_format. If prediction for any instance failed (partially or completely), then an additional errors_0001.<extension>, errors_0002.<extension>,…, errors_N.<extension> files are created (N depends on total number of failed predictions). These files contain the failed instances, as per their schema, followed by an additional error field which as value has \google.rpc.Status<Status>\__ containing only code and message fields.

  • bigquery_destination_prefix (Optional[str]) – The BigQuery project or dataset location where the output is to be written to. If project is provided, a new dataset is created with name prediction_<model-display-name>_<job-create-time> where is made BigQuery-dataset-name compatible (for example, most special characters become underscores), and timestamp is in YYYY_MM_DDThh_mm_ss_sssZ “based on ISO-8601” format. In the dataset two tables will be created, predictions, and errors. If the Model has both [instance][google.cloud.aiplatform.v1.PredictSchemata.instance_schema_uri] and [prediction][google.cloud.aiplatform.v1.PredictSchemata.parameters_schema_uri] schemata defined then the tables have columns as follows: The predictions table contains instances for which the prediction succeeded, it has columns as per a concatenation of the Model’s instance and prediction schemata. The errors table contains rows for which the prediction has failed, it has instance columns, as per the instance schema, followed by a single “errors” column, which as values has [google.rpc.Status][google.rpc.Status] represented as a STRUCT, and containing only code and message.

  • model_parameters (Optional[Dict]) – The parameters that govern the predictions. The schema of the parameters may be specified via the Model’s parameters_schema_uri.

  • machine_type (Optional[str]) – The type of machine for running batch prediction on dedicated resources. Not specifying machine type will result in batch prediction job being run with automatic resources.

  • accelerator_type (Optional[str]) – The type of accelerator(s) that may be attached to the machine as per accelerator_count. Only used if machine_type is set.

  • accelerator_count (Optional[int]) – The number of accelerators to attach to the machine_type. Only used if machine_type is set.

  • starting_replica_count (Optional[int]) – The number of machine replicas used at the start of the batch operation. If not set, Vertex AI decides starting number, not greater than max_replica_count. Only used if machine_type is set.

  • max_replica_count (Optional[int]) – The maximum number of machine replicas the batch operation may be scaled to. Only used if machine_type is set. Default is 10.

  • generate_explanation (bool) – Optional. Generate explanation along with the batch prediction results. This will cause the batch prediction output to include explanations based on the prediction_format:

    * bigquery: output includes a column named explanation. The value
    
    is a struct that conforms to the [aiplatform.gapic.Explanation] object.
    

>     * jsonl: The JSON objects on each line include an additional entry

>     keyed explanation. The value of the entry is a JSON object that
>     conforms to the [aiplatform.gapic.Explanation] object.


>     * csv: Generating explanations for CSV format is not supported.



* **explanation_metadata** (*aiplatform.explain.ExplanationMetadata*) – Optional. Explanation metadata configuration for this BatchPredictionJob.
Can be specified only if generate_explanation is set to True.

This value overrides the value of Model.explanation_metadata.
All fields of explanation_metadata are optional in the request. If
a field of the explanation_metadata object is not populated, the
corresponding field of the Model.explanation_metadata object is inherited.
For more details, see Ref docs <http://tinyurl.com/1igh60kt>



* **explanation_parameters** (*aiplatform.explain.ExplanationParameters*) – Optional. Parameters to configure explaining for Model’s predictions.
Can be specified only if generate_explanation is set to True.

This value overrides the value of Model.explanation_parameters.
All fields of explanation_parameters are optional in the request. If
a field of the explanation_parameters object is not populated, the
corresponding field of the Model.explanation_parameters object is inherited.
For more details, see Ref docs <http://tinyurl.com/1an4zake>



* **labels** (*Dict**[*[*str*](https://python.readthedocs.io/en/latest/library/stdtypes.html#str)*, *[*str*](https://python.readthedocs.io/en/latest/library/stdtypes.html#str)*]*) – Optional. The labels with user-defined metadata to organize your
BatchPredictionJobs. 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](https://goo.gl/xmQnxf)
for more information and examples of labels.


* **credentials** (*Optional**[**auth_credentials.Credentials**]*) – Custom credentials to use to create this batch prediction
job. Overrides credentials set in aiplatform.init.


* **encryption_spec_key_name** (*Optional**[*[*str*](https://python.readthedocs.io/en/latest/library/stdtypes.html#str)*]*) – Optional. The Cloud KMS resource identifier of the customer
managed encryption key used to protect the job. 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 this is set, then all
resources created by the BatchPredictionJob will
be encrypted with the provided encryption key.

Overrides encryption_spec_key_name set in aiplatform.init.



* **create_request_timeout** ([*float*](https://python.readthedocs.io/en/latest/library/functions.html#float)) – Optional. The timeout for the create request in seconds.


* **batch_size** ([*int*](https://python.readthedocs.io/en/latest/library/functions.html#int)) – Optional. The number of the records (e.g. instances) of the operation given in each batch
to a machine replica. Machine type, and size of a single record should be considered
when setting this parameter, higher value speeds up the batch operation’s execution,
but too high value will result in a whole batch not fitting in a machine’s memory,
and the whole operation will fail.
The default value is 64.


* **model_monitoring_objective_config** (*aiplatform.model_monitoring.ObjectiveConfig*) – Optional. The objective config for model monitoring. Passing this parameter enables
monitoring on the model associated with this batch prediction job.

only email alert is supported.


* **analysis_instance_schema_uri** ([*str*](https://python.readthedocs.io/en/latest/library/stdtypes.html#str)) – Optional. Only applicable if model_monitoring_objective_config is also passed.
This parameter specifies the YAML schema file uri describing the format of a single
instance that you want Tensorflow Data Validation (TFDV) to
analyze. If this field is empty, all the feature data types are
inferred from predict_instance_schema_uri, meaning that TFDV
will use the data in the exact format as prediction request/response.
If there are any data type differences between predict instance
and TFDV instance, this field can be used to override the schema.
For models trained with Vertex AI, this field must be set as all the
fields in predict instance formatted as string.


* **service_account** ([*str*](https://python.readthedocs.io/en/latest/library/stdtypes.html#str)) – Optional. Specifies the service account for workload run-as account.
Users submitting jobs must have act-as permission on this run-as account.

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.

• Parameters

  • dataset (Union[datasets.ImageDataset,datasets.TabularDataset,datasets.TextDataset,datasets.VideoDataset]) – Vertex AI to fit this training against. Custom training script should retrieve datasets through passed in environment variables uris:

The schema is defined as an OpenAPI 3.0.2 Schema Object The schema files that can be used here are found in gs://google-cloud-aiplatform/schema/dataset/annotation/, note that the chosen schema must be consistent with metadata of the Dataset specified by dataset_id.

    Only Annotations that both match this schema and belong to DataItems not ignored by the split method are used in respectively training, validation or test role, depending on the role of the DataItem they are on.

    When used in conjunction with annotations_filter, the Annotations used for training are filtered by both annotations_filter and annotation_schema_uri.

  • model_display_name (str) – If the script produces a managed Vertex AI Model. The display name of the Model. The name can be up to 128 characters long and can be consist of any UTF-8 characters.

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.

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.
