Class TabularDataset (1.74.0) 

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'])

Contrary to unstructured datasets, creating and importing a tabular dataset can only be done in a single step.

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"
)

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

    output_dir: str,
    annotation_filter: typing.Optional[str] = None,
    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

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.
Returns
Type Description
export_data_response (Dict) Response message for DatasetService.ExportData in Dictionary format.

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
