Hi,

I’m using `rasa 1.4.0` and I’m getting a few CountVectorizer warnings. Can you help me understand these issues? What is the impact on the model due to this?

```auto
2019-11-09 10:38:59 WARNING rasa.nlu.featurizers.count_vectors_featurizer - Unable to train CountVectorizer for message attribute text. Leaving an untrained CountVectorizer for it
2019-11-09 10:38:59 WARNING rasa.nlu.featurizers.count_vectors_featurizer - Unable to train CountVectorizer for message attribute intent. Leaving an untrained CountVectorizer for it
2019-11-09 10:38:59 DEBUG rasa.nlu.featurizers.count_vectors_featurizer - No text provided for response attribute in any messages of training data. Skipping training a CountVectorizer for it.

```

This is my `config.yml`

Hi there, what does your NLU data look like?

@pranavinu I think we fixed this issue. What version are you running, and what does your configuration look like?

Oh okay fair. that isn’t a warning message (it would be yellow if it was), just a debug message. that component could train a countvectorizer for responses, but there isn’t any data, so it will skip it. its nothing to worry about
