title: DeepLearning4J: org.nd4j.linalg.factory.Nd4jBackend$NoAvailableBackendException when running in jupyter
body: <p>I'm trying to run a DL4J example in a jupyter Notebook (IBM DSExperience) so I've ported the MLP Classifier example from Java to Scala, added the dependencies but currently struggling with the backend selection. I thought is would be sufficient just adding the following JAR
  %AddJar <a href="http://central.maven.org/maven2/org/nd4j/nd4j-x86/0.4-rc3.8/nd4j-x86-0.4-rc3.8.jar" rel="nofollow">http://central.maven.org/maven2/org/nd4j/nd4j-x86/0.4-rc3.8/nd4j-x86-0.4-rc3.8.jar</a> so that the classloader in org.nd4j.linalg.factory.Nd4jBackend can pick it up, but unfortunately I get:</p>
  
  <blockquote>
    <p>Name: java.lang.NoClassDefFoundError Message:
    org.nd4j.linalg.factory.Nd4jBackend$NoAvailableBackendException</p>
  </blockquote>
  
  <p>I've put the complete code into a <a href="https://gist.github.com/romeokienzler/ad1ca47dc9ac1751ed681dd7b9947f39" rel="nofollow">GIST</a></p>
