__init__

__init__(domain: Domain, intents: TrainingData, story_graph: StoryGraph, config: Optional[Dict[Text, Any]]) -> None

Initializes the Validator object.

Arguments:

• domain - The domain.
• intents - Training data.
• story_graph - The story graph.
• config - The configuration.

from_importer

@classmethod
async from_importer(cls, importer: TrainingDataImporter) -> "Validator"

Create an instance from the domain, nlu and story files.

verify_intents

verify_intents(ignore_warnings: bool=True) -> bool

Compares list of intents in domain with intents in NLU training data.

verify_example_repetition_in_intents

verify_example_repetition_in_intents(ignore_warnings: bool=True) -> bool

Checks if there is no duplicated example in different intents.

verify_intents_in_stories

verify_intents_in_stories(ignore_warnings: bool=True) -> bool

Checks intents used in stories.

Verifies if the intents used in the stories are valid, and whether all valid intents are used in the stories.

verify_utterances_in_stories

verify_utterances_in_stories(ignore_warnings: bool=True) -> bool

Verifies usage of utterances in stories.

Checks whether utterances used in the stories are valid, and whether all valid utterances are used in stories.

verify_actions_in_stories_rules

verify_actions_in_stories_rules() -> bool

Verifies that actions used in stories and rules are present in the domain.

verify_story_structure

verify_story_structure(ignore_warnings: bool=True, max_history: Optional[int]=None) -> bool

Verifies that the bot behaviour in stories is deterministic.

Arguments:

• ignore_warnings - When True, return True even if conflicts were found.
• max_history - Maximal number of events to take into account for conflict identification.

Returns:

False is a conflict was found and ignore_warnings is False. True otherwise.

verify_nlu

verify_nlu(ignore_warnings: bool=True) -> bool

Runs all the validations on intents and utterances.

verify_form_slots

verify_form_slots() -> bool

Verifies that form slots match the slot mappings in domain.

verify_domain_validity

verify_domain_validity() -> bool

Checks whether the domain returned by the importer is empty.

An empty domain or one that uses deprecated Mapping Policy is invalid.

verify_domain_duplicates

verify_domain_duplicates() -> bool

Verifies that there are no duplicated dictionaries in multiple domain files.
