Hi Pat, I have a Ubuntu machine which PredictionIo (0.9.7-aml) installed on it, I have two application both based on Universal recommender template. I trained both of the apps and deployed them on different ports . Results of the apps were quite normal but the problem which I figured out later is that one of the apps was predicting items with score zero so I retrained it then scores become normal numbers but after this action (retraining) the other app start returning empty results, so I retrained that one and then the first one returned zero score items again .
This is like closed circle and retraining each of apps causes the other app return empty results or abnormal zero scored results.

Instructions are here on actionml.com<http://actionml.com> or here for Apache PIO: http://predictionio.incubator.apache.org/install/ I don't understand your explanation, there should be one train per PredictionServer, you can't have one PS and two "engines" or configurations. The 2 engines must be on 2 different ports if deployed separately. Can you explain your setup and what you are trying to do?

I have two application running on one predictionio engine, each time I train one of them the other one's predictions returning zero score items for one of them and no items at all for the other. I am using UR algorithm for both of apps pio version : 0.9.7-aml regards
