The operator class 'h2o:deep_learning' is unknown. Possibly you must install a plugin for operators
My RapidMiner process works fine in RapidMiner Studio.
However, if I try to run it from Java I get an error message saying "a dummy operator" cannot be executed, in my case it's the Deep Learning operator.
I had this problem before with Cross Validation Operator but by searching the posts here I found out that I had to register the extra plugins. That did solve my problem with the Cross Validation operator but unfortunately the problem with the H20 Deep Learning Operator remains.
// loads the process from the repository (if you do not have one, see alternative below)
RepositoryLocation pLoc = new RepositoryLocation("//Local Repository/processes/STELA_Studieduur_Learner");
ProcessEntry pEntry = (ProcessEntry) pLoc.locateEntry();
String processXML = pEntry.retrieveXML();
Process myProcess = new Process(processXML);
IOContainer ioResult = myProcess.run();
The JAR file is present in the plugins directory however: /opt/rapidminer/lib/plugins/h2o-7.3.0-all.jar
I also tried to add it directly to my classpath without succes.
I don't know if this is a related issue but I also get an 'Caused by: java.lang.ClassNotFoundException: com.rapidminer.tools.nexus.NexusCommunicationException' and a warning : 'Plugin initializer com.rapidminer.PluginInitCloudExecution.initPlugin of Plugin Cloud Execution caused an error: null '
Any ideas on how to solve this?
