I tried letting the library pick the threshold. It picked 1 and the final results were the same. I even tried setting the threshold to negative infinity, with no success.

It makes sense that the recommender is not called. That would be caused by some of the reasons I listed below. The wrong relevance threshold would indeed cause the recommender to not be called. If there are no relevant items for a user, it can't really proceed at all. Have you tried setting the threshold to NaN to let the library pick? or the other items I mentioned. You really might need a debugger to look inside and see what the real reason is.
