Managing datasets

A project can have multiple datasets, each used to train a separate model. You can get a list of the available datasets and can delete datasets you no longer need.

For information about creating a dataset and importing data into it, see Creating datasets and importing data.

Listing datasets

A project can include numerous datasets. This section describes how to retrieve a list of the available datasets for a project.

To see a list of the available datasets using the AutoML Natural Language UI, click the Datasets link at the top of the left navigation menu.

To see the datasets for a different project, select the project from the drop-down list in the upper right of the title bar.

REST & CMD LINE

Before using any of the request data below, make the following replacements:

  • project-id: your project ID
  • location-id: the location for the resource, us-central1 for the Global location or eu for the European Union

HTTP method and URL: 

GET https://automl.googleapis.com/v1/projects/project-id/locations/location-id/datasets

To send your request, expand one of these options:

You should receive a JSON response similar to the following:

  "datasets": [

Export a dataset

You can export a CSV file with all a dataset's information to a Cloud Storage bucket. The exported CSV file has the same format as the training data import CSV.

To export a dataset:

  1. Select the dataset you want to export documents into from the Datasets page.

  2. Click the Export data option at the top of the Dataset details page.

  3. Navigate to the Cloud Storage bucket where you want to write the export CSV file.

  4. Click Export CSV.

    You will receive an email when the data export process has completed.
