I'm trying to cluster with a categorized data. But I get 'non numerical attrıbute error.

Depending on the clustering algorithm/operator that you use, if it is using value-based similarity, therefore, you need to convert your categorical data into numeric. Perhaps share your .rpm and data files for more accurate solution? I am simply guessing here.
