trouble using user K-NN(recommender system)
Contributor I
Hi everybody!!
I'm new using RapidMiner, I keep on this video http://www.screencast.com/users/DataMiningINCAE/folders/Tutoriales Adicionales de Rapid Miner/media/a23acb02-4bc1-4821-9b4b-30d8e27476d4 with this data http://www.informatik.uni-freiburg.de/~cziegler/BX/BX-CSV-Dump.zip (Book Ratings) and I have an error, in User K-NN I search here for similarity problems but I don't find anything which help me.
This is my log.

User k-NN is from an extension that is not maintained by RapidMiner, right? In that case please contact the maintainer of the extension. Please correct me if I am wrong.
Best regards,
