find_training_job.run_and_wait()

Hi,
I followed the notebooks and got stuck on the notebook 01_initial_workflow

executing find_training_job.run_and_wait() gives me the error

Job in INTERNAL_ERROR state at 331 seconds since launch.  Waiting 30 seconds before checking again

I am wondering because this step should not take so long. Could that an error of the API class defined in o intro and config???
