Class TabularDataset (1.36.4)

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

A managed tabular dataset resource for Vertex AI.

Use this class to work with tabular datasets. You can use a CSV file, BigQuery, or a pandas DataFrame to create a tabular dataset. For more information about paging through BigQuery data, see Read data with BigQuery API using pagination. For more information about tabular data, see Tabular data.

The following code shows you how to create and import a tabular dataset with a CSV file.

my_dataset = aiplatform.TabularDataset.create(
    display_name="my-dataset", gcs_source=['gs://path/to/my/dataset.csv'])

The following code shows you how to create and import a tabular dataset in two distinct steps.

my_dataset = aiplatform.TextDataset.create(
    display_name="my-dataset")

my_dataset.import(
    gcs_source=['gs://path/to/my/dataset.csv']
    import_schema_uri=aiplatform.schema.dataset.ioformat.text.multi_label_classification
)

If you create a tabular dataset with a pandas DataFrame, you need to use a BigQuery table to stage the data for Vertex AI:

my_dataset = aiplatform.TabularDataset.create_from_dataframe(
    df_source=my_pandas_dataframe,
    staging_path=f"bq://{bq_dataset_id}.table-unique"
)

) -> google.cloud.aiplatform.datasets.tabular_dataset.TabularDataset

Creates a tabular dataset.

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]]` 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"]`.
`bq_source`	`str` The URI to a BigQuery table that's used as an input source. For example, `bq://project.dataset.table_name`.
`project`	`str` The name of the Google Cloud project to which this `TabularDataset` is uploaded. This overrides the project that was set by `aiplatform.init`.
`location`	`str` The Google Cloud region where this dataset is uploaded. This region overrides the region that was set by `aiplatform.init`.
`credentials`	`auth_credentials.Credentials` The credentials that are used to upload the `TabularDataset`. These credentials override the credentials set by `aiplatform.init`.
`request_metadata`	`Sequence[Tuple[str, str]]` 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.

create_from_dataframe

create_from_dataframe(
    df_source: pd.DataFrame,
    staging_path: str,
    bq_schema: typing.Optional[
        typing.Union[str, google.cloud.bigquery.schema.SchemaField]
    ] = None,

) -> TabularDataset

Creates a new tabular dataset from a pandas DataFrame.

Parameters
Name	Description
`staging_path`	`str` Required. The BigQuery table used to stage the data for Vertex AI. Because Vertex AI maintains a reference to this source to create the `TabularDataset`, you shouldn't delete this BigQuery table. For example: `bq://my-project.my-dataset.my-table`. If the specified BigQuery table doesn't exist, then the table is created for you. If the provided BigQuery table already exists, and the schemas of the BigQuery table and your DataFrame match, then the data in your local `DataFrame` is appended to the table. The location of the BigQuery table must conform to the BigQuery location requirements.
`bq_schema`	`Optional[Union[str, bigquery.SchemaField]]` Optional. If not set, BigQuery autodetects the schema using the column types of your `DataFrame`. If set, BigQuery uses the schema you provide when the staging table is created. For more information, see the BigQuery `LoadJobConfig.schema` property.
`display_name`	`str` Optional. The user-defined name of the `Dataset`. The name must contain 128 or fewer UTF-8 characters.
`project`	`str` Optional. The project to upload this dataset to. This overrides the project set using `aiplatform.init`.
`location`	`str` Optional. The location to upload this dataset to. This overrides the location set using `aiplatform.init`.
`credentials`	`auth_credentials.Credentials` Optional. The custom credentials used to upload this dataset. This overrides credentials set using `aiplatform.init`.
`df_source`	`pd.DataFrame` Required. A pandas `DataFrame` containing the source data for ingestion as a `TabularDataset`. This method uses the data types from the provided `DataFrame` when the `TabularDataset` is created.

Returns
Type	Description
`tabular_dataset (TabularDataset)`	An instantiated representation of the managed `TabularDataset` resource.

delete

delete(sync: bool = True) -> None

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) -> 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.

import_data

import_data()

Upload data to existing managed dataset.

Parameters
Name	Description
`gcs_source`	`Union[str, Sequence[str]]` Required. Google Cloud Storage URI(-s) to the input file(s). May contain wildcards. For more information on wildcards, see https://cloud.google.com/storage/docs/gsutil/addlhelp/WildcardNames. .. rubric:: Examples str: "gs://bucket/file.csv" Sequence[str]: ["gs://bucket/file1.csv", "gs://bucket/file2.csv"]
`import_schema_uri`	`str` Required. 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. This arg is not for specifying the annotation name or the training target of your data, but for some global labels of the dataset. E.g., 'data_item_labels={"aiplatform.googleapis.com/ml_use":"training"}' specifies that all the uploaded data are used for training.
`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.
`import_request_timeout`	`float` Optional. The timeout for the import request in seconds.

Returns
Type	Description
`dataset (Dataset)`	Instantiated representation of the managed dataset resource.
