IndexError: index 64 is out of bounds for axis 0 with size 64

Hi community,

I have 5 stories in my stories.yml file. Whenever I tried writing 6th story with new intent and action, I am getting this error: “IndexError: index 64 is out of bounds for axis 0 with size 64”

If I put this new intent and action in the 5th story, it will work. Why is it happening?

Hello, @shaur.sum10 ! This has become a big pain for me in the last few days. And I created a topic: Error running graph component for node train_UnexpecTEDIntentPolicy2

But after that I found out that the problem is not in intents and entities, but in the number of stories that you submit for training. I had 17 stories and they gave the following error, if I add this number to 21 or more, then everything becomes normal. We must take into account, as I understand it, that stories are automatically augmented, and elements such as the - or: operator create several stories from one at once. So in fact, having 5 stories, with training they can turn into some more stories.

I tried to work through the rasa code, but the logic behind the output_scores["similarities"][index, 0, candidate_label_id] expression contains a lot of pre-processing. This looks very much like a bug that should be investigated by the developers.

There is already a JIRA for that issue: [OSS-736] - Jira My workaround was to downgrade to 3.6.9 for the time being.

I’ve solve the problem by reducing the number of story. Instead of writing new story and repeating some steps just to finaly add my new intent and action. I just wrote a story about a context (discussion path), and add my new intents et actions to the appriope discussion path, i mean in the occasion user can invoke the intent.
