rasa2.0/lib/python3.7/site-packages/rasa/nlu/classifiers/diet_classifier.py:683: VisibleDeprecationWarning: Creating an ndarray from ragged nested sequences (which is a list-or-tuple of lists-or-tuples-or ndarrays with different lengths or shapes) is deprecated. If you meant to do this, you must specify ‘dtype=object’ when creating the ndarray X_dense_sequence = np.array(X_dense_sequence)
