View source on GitHub

Get the domain associated with the input feature from the schema.

tfdv.get_domain(
    schema,
    feature_path
)

Args:

  • schema: A Schema protocol buffer.
  • feature_path: The path of the feature whose domain needs to be found. If a FeatureName is passed, a one-step FeaturePath will be constructed and used. For example, "my_feature" -> types.FeaturePath(["my_feature"])

Returns:

The domain protocol buffer (one of IntDomain, FloatDomain, StringDomain or BoolDomain) associated with the input feature.

Raises:

  • TypeError: If the input schema is not of the expected type.
  • ValueError: If the input feature is not found in the schema or there is no domain associated with the feature.
