This recipe assumes that you already have the Keras model (pre-trained/not pre-trained) set up and ready to be imported to DL4J. We will skip the details about how to save Keras models to disk as it is beyond the scope of this book. Usually, Keras models are stored in .h5 format, but that isn't a restriction as the model-import API can import from other formats as well. As a prerequisite, we need to add the following Maven dependency in pom.xml:

<dependency>
   <groupId>org.deeplearning4j</groupId>
   <artifactId>deeplearning4j-modelimport</artifactId>
   <version>1.0.0-beta3</version>
 </dependency>
