Caused by: java.lang.RuntimeException: Error deserializing ComputationGraphConfiguration - configuration may have a custom layer, vertex or preprocessor, in pre version 1.0.0-beta JSON format.
Models in legacy format with custom layers should be loaded in 1.0.0-beta to 1.0.0-beta4 and saved again, before loading in the current version of DL4J
