Class TextDataset (1.65.0)

TextDataset(
    dataset_name: str,
    project: typing.Optional[str] = None,
    location: typing.Optional[str] = None,
    credentials: typing.Optional[google.auth.credentials.Credentials] = None,
)

A managed text dataset resource for Vertex AI.

Use this class to work with a managed text dataset. To create a managed text dataset, you need a datasource file in CSV format and a schema file in YAML format. A schema is optional for a custom model. The CSV file and the schema are accessed in Cloud Storage buckets.

Use text data for the following objectives:

Classification. For more information, see Prepare text training data for classification.
Entity extraction. For more information, see Prepare text training data for entity extraction.
Sentiment analysis. For more information, see [Prepare text training data for sentiment analysis](Prepare text training data for sentiment analysis).

The following code shows you how to create and import a text dataset with a CSV datasource file and a YAML schema file. The schema file you use depends on whether your text dataset is used for single-label classification, multi-label classification, or object detection.

my_dataset = aiplatform.TextDataset.create(
    display_name="my-text-dataset",
    gcs_source=['gs://path/to/my/text-dataset.csv'],
    import_schema_uri=['gs://path/to/my/schema.yaml'],
)

create

create(
    display_name: typing.Optional[str] = None,
    gcs_source: typing.Optional[typing.Union[str, typing.Sequence[str]]] = None,
    import_schema_uri: typing.Optional[str] = None,
    data_item_labels: typing.Optional[typing.Dict] = None,
    project: typing.Optional[str] = None,
    location: typing.Optional[str] = None,
    credentials: typing.Optional[google.auth.credentials.Credentials] = None,
    request_metadata: typing.Optional[typing.Sequence[typing.Tuple[str, str]]] = (),
    labels: typing.Optional[typing.Dict[str, str]] = None,
    encryption_spec_key_name: typing.Optional[str] = None,
    sync: bool = True,
    create_request_timeout: typing.Optional[float] = None,
) -> google.cloud.aiplatform.datasets.text_dataset.TextDataset

Creates a new text dataset.

Optionally imports data into this dataset when a source and import_schema_uri are passed in. The following is an example of how this method is used:

ds = aiplatform.TextDataset.create(
        display_name='my-dataset',
        gcs_source='gs://my-bucket/dataset.csv',
        import_schema_uri=aiplatform.schema.dataset.ioformat.text.multi_label_classification
    )

Parameters
Name	Description
`display_name`	`str` Optional. The user-defined name of the dataset. The name must contain 128 or fewer UTF-8 characters.
`gcs_source`	`Union[str, Sequence[str]]` Optional. The URI to one or more Google Cloud Storage buckets that contain your datasets. For example, `str: "gs://bucket/file.csv"` or `Sequence[str]: ["gs://bucket/file1.csv", "gs://bucket/file2.csv"]`.
`import_schema_uri`	`str` Optional. A URI for a YAML file stored in Cloud Storage that describes the import schema used to validate the dataset. The schema is an OpenAPI 3.0.2 Schema object.
`data_item_labels`	`Dict` Optional. A dictionary of label information. Each dictionary item contains a label and a label key. Each item in the dataset includes one dictionary of label information. If a data item is added or merged into a dataset, and that data item contains an image that's identical to an image that’s already in the dataset, then the data items are merged. If two identical labels are detected during the merge, each with a different label key, then one of the label and label key dictionary items is randomly chosen to be into the merged data item. Data items are compared using their binary data (bytes), not on their content. If annotation labels are referenced in a schema specified by the `import_schema_url` parameter, then the labels in the `data_item_labels` dictionary are overriden by the annotations.
`project`	`str` Optional. The name of the Google Cloud project to which this `TextDataset` is uploaded. This overrides the project that was set by `aiplatform.init`.
`location`	`str` Optional. The Google Cloud region where this dataset is uploaded. This region overrides the region that was set by `aiplatform.init`.
`credentials`	`auth_credentials.Credentials` Optional. The credentials that are used to upload the `TextDataset`. These credentials override the credentials set by `aiplatform.init`.
`request_metadata`	`Sequence[Tuple[str, str]]` Optional. Strings that contain metadata that's sent with the request.
`labels`	`Dict[str, str]` Optional. Labels with user-defined metadata to organize your Vertex AI Tensorboards. The maximum length of a key and of a value is 64 unicode characters. Labels and keys can contain only lowercase letters, numeric characters, underscores, and dashes. International characters are allowed. No more than 64 user labels can be associated with one Tensorboard (system labels are excluded). For more information and examples of using labels, see Using labels to organize Google Cloud Platform resources. System reserved label keys are prefixed with `aiplatform.googleapis.com/` and are immutable.
`encryption_spec_key_name`	`Optional[str]` Optional. The Cloud KMS resource identifier of the customer managed encryption key that's used to protect the dataset. The format of the key is `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 `encryption_spec_key_name` is set, this `TextDataset` and all of its sub-resources are secured by this key. This `encryption_spec_key_name` overrides the `encryption_spec_key_name` set by `aiplatform.init`.
`sync`	`bool` If `true`, the `create` method creates a text dataset synchronously. If `false`, the `create` method creates a text dataset asynchronously.
`create_request_timeout`	`float` Optional. The number of seconds for the timeout of the create request.

Returns
Type	Description
`text_dataset (TextDataset)`	An instantiated representation of the managed `TextDataset` resource.

delete

delete(sync: bool = True) -> None

export_data

export_data(output_dir: str) -> typing.Sequence[str]

Exports data to output dir to GCS.

Parameter

Name Description

output_dir

str

Required. The Google Cloud Storage location where the output is to be written to. In the given directory a new directory will be created with name: export-data- where timestamp is in YYYYMMDDHHMMSS format. All export output will be written into that directory. Inside that directory, annotations with the same schema will be grouped into sub directories which are named with the corresponding annotations' schema title. Inside these sub directories, a schema.yaml will be created to describe the output format. If the uri doesn't end with '/', a '/' will be automatically appended. The directory is created if it doesn't exist.

Returns
Type	Description
`exported_files (Sequence[str])`	All of the files that are exported in this export operation.

export_data_for_custom_training

export_data_for_custom_training(
    output_dir: str,

    saved_query_id: typing.Optional[str] = None,
    annotation_schema_uri: typing.Optional[str] = None,
    split: typing.Optional[
        typing.Union[typing.Dict[str, str], typing.Dict[str, float]]
    ] = None,
) -> typing.Dict[str, typing.Any]

Exports data to output dir to GCS for custom training use case.

Example annotation_schema_uri (image classification): gs://google-cloud-aiplatform/schema/dataset/annotation/image_classification_1.0.0.yaml

Example split (filter split): { "training_filter": "labels.aiplatform.googleapis.com/ml_use=training", "validation_filter": "labels.aiplatform.googleapis.com/ml_use=validation", "test_filter": "labels.aiplatform.googleapis.com/ml_use=test", } Example split (fraction split): { "training_fraction": 0.7, "validation_fraction": 0.2, "test_fraction": 0.1, }

Parameters
Name	Description
`output_dir`	`str` Required. The Google Cloud Storage location where the output is to be written to. In the given directory a new directory will be created with name: `export-data-` where timestamp is in YYYYMMDDHHMMSS format. All export output will be written into that directory. Inside that directory, annotations with the same schema will be grouped into sub directories which are named with the corresponding annotations' schema title. Inside these sub directories, a schema.yaml will be created to describe the output format. If the uri doesn't end with '/', a '/' will be automatically appended. The directory is created if it doesn't exist.
`annotation_filter`	`str` Optional. An expression for filtering what part of the Dataset is to be exported. Only Annotations that match this filter will be exported. The filter syntax is the same as in `ListAnnotations][DatasetService.ListAnnotations]`.
`saved_query_id`	`str` Optional. The ID of a SavedQuery (annotation set) under this Dataset used for filtering Annotations for training. Only used for custom training data export use cases. Only applicable to Datasets that have SavedQueries. Only Annotations that are associated with this SavedQuery are used in respectively training. When used in conjunction with annotations_filter, the Annotations used for training are filtered by both saved_query_id and annotations_filter. Only one of saved_query_id and annotation_schema_uri should be specified as both of them represent the same thing: problem type.
`annotation_schema_uri`	`str` Optional. The Cloud Storage URI that points to a YAML file describing the annotation schema. 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_schema_uri of this Dataset. Only used for custom training data export use cases. Only applicable if this Dataset that have DataItems and Annotations. 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.
`split`	`Union[Dict[str, str], Dict[str, float]]` The instructions how the export data should be split between the training, validation and test sets.
