Hi Norman, thanks for bringing this up, this is a very important point! CUDNN makes a huge difference in training time. We recently removed libccaffe from the codebase and replaced it with JavaCPP (see #72). This makes deployment a lot easier, so the user doesn't have to build libccaffe. The downside is that we currently haven't enabled GPUs with JavaCPP because of a bug bytedeco/javacpp-presets#147. We're working on figuring this out. Once that's done we will support CUDNN!

Thank you. Working with bytedeco/javacpp seems to be very good approach.
