I follow a tutorial and created two modules for training my chatbot based in a domain and stories, but when I running the online training module, the follow errors appears: /env/rasa/lib/python3.6/site-packages/sklearn/preprocessing/label.py:151: DeprecationWarning: The truth value of an empty array is ambiguous. Returning False, but in future this will result in an error. Use `array.size > 0` to check that an array is not empty. if diff: But it is possible ignore this and continue executing, but in the final steps of my storie, crashs and show this: ERROR:rasa_core.training.interactive:An exception occurred while recording messages. Traceback (most recent call last): File "/home/henrique/Documents/env/rasa/lib/python3.6/site-packages/rasa_core/training/interactive.py", line 1286, in record_messages finetune, sender_ids, plot_file) File "/home/henrique/Documents/env/rasa/lib/python3.6/site-packages/rasa_core/training/interactive.py", line 863, in _predict_till_next_listen unconfirmed=[ActionExecuted(action_name)]) File "/home/henrique/Documents/env/rasa/lib/python3.6/site-packages/rasa_core/training/interactive.py", line 1220, in _plot_trackers max_history=2) File "/home/henrique/Documents/env/rasa/lib/python3.6/site-packages/rasa_core/training/visualization.py", line 453, in visualize_neighborhood _merge_equivalent_nodes(graph, max_history) File "/home/henrique/Documents/env/rasa/lib/python3.6/site-packages/rasa_core/training/visualization.py", line 204, in _merge_equivalent_nodes _nodes_are_equivalent(graph, i, j, max_history): File "/home/henrique/Documents/env/rasa/lib/python3.6/site-packages/rasa_core/training/visualization.py", line 148, in _nodes_are_equivalent _fingerprint_node(graph, node_a, max_history) == File "/home/henrique/Documents/env/rasa/lib/python3.6/site-packages/rasa_core/training/visualization.py", line 115, in _fingerprint_node for continuation in continuations} File "/home/henrique/Documents/env/rasa/lib/python3.6/site-packages/rasa_core/training/visualization.py", line 115, in <setcomp> for continuation in continuations} TypeError: sequence item 1: expected str instance, dict found Searching in forums a solution is update the numpy but it’s don’t work. Sorry, but I cannot expose more details because I don’t have experience with Rasa before.
