PredictionIO issue issue

I am running pio deployand it seems there are no errors, however I am not sure that everything works without problems. Do any of the warnings below indicate anything that indicates that it is not working?

PredictionIO cannot get your trained model. Try checking pio-env.sh where the model is stored and it is available for forecasting .IO
