If you watched this great introduction on Deep Learning with Keras and RapidMiner here, you probably want to try it out! I’ll warn you though, it’s a bit tricky to get this up and running on a Windows machine.
The best place to read up on how to do it is in this KB thread at the RapidMiner Community. Installing Keras is heavily dependent on the Python version, additional python modules, and operating system versions too. Of course, if you get stuck, the KB article is a great place to post your questions.
