python -m rasa_core.run -d models/dialogue -u models/current/nlu --endpoints endpoints.yml when i ran the above command i am getting error linke rasa_nlu.model.UnsupportedModelError: The model version is to old to be loaded by this Rasa NLU instance. Either retrain the model, or run withan older version. Model version: 0.14.6 Instance version: 0.15.1

The version of the model (0.14.6) is not compatible with the Rasa version (0.15.1) you are using. As mentioned in the error message, you have two possibilities:

  1. Retrain the model with your current Rasa version
  2. Switch to the Rasa version compatible with the model version
