Java Deep Learning Cookbook

How it works...

To mitigate exceptions such as ClassNotFoundException, the primary task is to verify we installed the JDK properly (step 2) and whether the environment variables we set up point to the right place. Step 3 is also important as the missing dependencies result in the same error.

In step 4, we are removing redundant dependencies that are present in the local repository and are attempting a fresh Maven build. Here is a sample for NoClassDefFoundError while trying to run a DL4J application:

root@instance-1:/home/Deeplearning4J# java -jar target/dl4j-1.0-SNAPSHOT.jar 09:28:22.171 [main] INFO org.nd4j.linalg.factory.Nd4jBackend - Loaded [JCublasBackend] backend Exception in thread "main" java.lang.NoClassDefFoundError: org/nd4j/linalg/api/complex/IComplexDouble ...
