Why am I getting an
The complete warning is:
UndefinedMetricWarning: F-score is ill-defined and being set to 0.0 in labels with no predicted samples.
The warning is a result of a lack of training data. During the training the dataset will be splitted multiple times, if there are to few training samples for any of the intents, the splitting might result in splits that do not contain any examples for this intent.
Hence, the solution is to add more training samples. As this is only a warning, training will still succeed, but the resulting models predictions might be weak on the intents where you are lacking training data.
