Entity tagging and duckling

On this video it’s mentioned Using Duckling for Entity Extraction with Rasa | Rasa Tutorial - YouTube that there is no need to tag an entity if duckling is used. if then how do we extract entity with roles and groups

eg: " I need 2 pizza and 1 diet coke"

Hi @athulvingt - you will have to extract those entities with DIET or the CRDEntityExtractor. The duckling component unfortunately doesn’t support entity roles and groups
