Hi there Piyush, It seems that you're using an old version of mlpack, where DTree is not templatized. The templatization of DTree happened after the release of mlpack 2.1.0, so if you are using mlpack 2.1.0 then you should use the class "DTree", and if git master, you can use "DTree<arma::Mat<float>>". I hope this is helpful. Let me know if I can clarify anything. Thanks, Ryan -- Ryan Curtin | "Do I sound like I'm ordering a pizza?"
