Cannot import name 'MESSAGE_VECTOR_FEATURE_NAMES' from 'rasa.nlu.constants'


cannot import name ‘MESSAGE_VECTOR_FEATURE_NAMES’ from ‘rasa.nlu.constants’

I am getting this error while running a custom Bert classifier.

My rasa version: Rasa Version : 2.6.1 Minimum Compatible Version: 2.6.0 Rasa SDK Version : 2.6.0 Rasa X Version : 0.39.3 Python Version : 3.7.9 Operating System : Windows-10-10.0.18362-SP0

any help would be appreciated.


This is a constant from a very old version of Rasa. Are you migrating your custom classifier from a lower version?
