@dszeto is right. What i what i meant to say is that the package names in
this tutorial should be renamed from `org.template.classification` to
`org.example.classification` because this tutorial links to
https://github.com/apache/predictionio-template-attribute-based-classifier/blob/develop/src/main/scala/Evaluation.scala
which probably was updated so the tutorial is not obsolete.---
