    The type of the dataset that you want to list. Specify train to list the training dataset. Specify test to list the test dataset. If you have a single dataset project, specify train.

  • Labeled (boolean) – Specify true to include labeled entries, otherwise specify false. If you don’t specify a value, Lookout for Vision returns all entries.
