Attribute
| Name | Description |
| key | str
Required. The key is a name of one of the Dataset's data columns. The value of the key (either the label's value or value in the column) must be one of {``training``, ``validation``, ``test``}, and it defines to which set the given piece of data is assigned. If for a piece of data the key is not present or has an invalid value, that piece is ignored by the pipeline. |
