Hi Pat, Thanks for your help, problem fixed. The issue was about using same indexNames, everything else was correct except indexName.

Make sure there are different "indexName" set for each model in the 2 engine.json files. Otherwise training of one engine will wipe out the other since they point to the same indexName. To have 2 completely separate applications with different data you need: 1) 2 different EventServer appNames with different appids, create with `pio app new <your-app-name>` 2) 2 different indexNames for 2 models, set in the 2 engine.json files 3) each engine deployed on a separate port (you have this already) On Jan 13, 2017, at 12:35 AM, Hossein Bahrami <h.bahr...@live.com<mailto:h.bahr...@live.com>> wrote: 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
