I have a problem when I parse my model the intent is null, and when I try to train again my model I get the following error:
RasaNLUModelConfig(model_config), model_name) concurrent.futures.process.BrokenProcessPool: A process in the process pool was terminated abruptly while the future was running or pending.
/usr/local/lib/python3.6/multiprocessing/semaphore_tracker.py:143: UserWarning: semaphore_tracker: There appear to be 1 leaked semaphores to clean up at shutdown len(cache))
and after that I have to restart rasa, help please.
