How to compute several precisions & how to load a model #322

Hello, I have two questions:

how can I compute precision@10, precision@5, precision@3 and precision@1 all together? If in my config file I write:

rec.recommender.ranking.topn=10
rec.recommender.ranking.topn=5
rec.recommender.ranking.topn=3
rec.recommender.ranking.topn=1

.. librec will alway compute only the last one (in this case precision@1)

is there a way to train and store a model, and then load it in order to calculate other metrics?

Thanks
