Methods

TextDataset

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

Retrieves an existing managed dataset given a dataset name or ID.

Parameters

Name	Description
dataset_name	str Required. A fully-qualified dataset resource name or dataset ID. Example: "projects/123/locations/us-central1/datasets/456" or "456" when project and location are initialized or passed.
project	str Optional project to retrieve dataset from. If not set, project set in aiplatform.init will be used.
location	str Optional location to retrieve dataset from. If not set, location set in aiplatform.init will be used.
credentials	auth_credentials.Credentials Custom credentials to use to retrieve this Dataset. Overrides credentials set in aiplatform.init.

create

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

Creates a new text dataset and optionally imports data into dataset when source and import_schema_uri are passed.

Example Usage: 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 can be up to 128 characters long and can be consist of any UTF-8 characters.
gcs_source	Union[str, Sequence[str]] Google Cloud Storage URI(-s) to the input file(s). .. rubric:: Examples str: "gs://bucket/file.csv" Sequence[str]: ["gs://bucket/file1.csv", "gs://bucket/file2.csv"]
import_schema_uri	str Points to a YAML file stored on Google Cloud Storage describing the import format. Validation will be done against the schema. The schema is defined as an OpenAPI 3.0.2 Schema Object https://tinyurl.com/y538mdwt__.
data_item_labels	Dict Labels that will be applied to newly imported DataItems. If an identical DataItem as one being imported already exists in the Dataset, then these labels will be appended to these of the already existing one, and if labels with identical key is imported before, the old label value will be overwritten. If two DataItems are identical in the same import data operation, the labels will be combined and if key collision happens in this case, one of the values will be picked randomly. Two DataItems are considered identical if their content bytes are identical (e.g. image bytes or pdf bytes). These labels will be overridden by Annotation labels specified inside index file referenced by import_schema_uri, e.g. jsonl file.
project	str Project to upload this dataset to. Overrides project set in aiplatform.init.
location	str Location to upload this dataset to. Overrides location set in aiplatform.init.
credentials	auth_credentials.Credentials Custom credentials to use to upload this dataset. Overrides credentials set in aiplatform.init.
request_metadata	Sequence[Tuple[str, str]] Strings which should be sent along with the request as metadata.
labels	Dict[str, str] Optional. Labels with user-defined metadata to organize your Tensorboards. 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. No more than 64 user labels can be associated with one Tensorboard (System labels are excluded). See https://goo.gl/xmQnxf for more information and examples of labels. 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 used to protect the dataset. 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 Dataset and all sub-resources of this Dataset will be secured by this key. Overrides encryption_spec_key_name set in aiplatform.init.
sync	bool 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.

Returns

Type	Description
text_dataset (TextDataset)	Instantiated representation of the managed text dataset resource.

delete

delete(sync: bool = True)

Deletes this Vertex AI resource. WARNING: This deletion is permanent.

Parameter

Name	Description
sync	bool Whether to execute this deletion 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.

export_data

export_data(output_dir: 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.

import_data
