Problem while integrating RapidMiner using Eclipse

Aldi

Hello, I am trying to integrate RapidMiner into my Java Application using Eclipse, I was trying to use the model in my process and extract the results (tree, performance, and table) and show them in my application. But there were a few errors, here are the code and the output.

import java.awt.*;

try {

RapidMiner.setExecutionMode(RapidMiner.ExecutionMode.COMMAND_LINE);

RapidMiner.init();

Plugin.setPluginLocation("D:/RapidMiner Studio/lib/plugins");

Plugin.addAdditionalExtensionDir("D:/RapidMiner Studio/lib/plugins");

Plugin.setInitPlugins(true);

Repository repo = RepositoryManager.getInstance(null).getRepository("Projects");

Process process = processLocation.load(null);

// Operator tree = process.getOperator("Decision Tree");

process.run();

} catch (IOException | XMLException ex) {

ex.printStackTrace();

}

}

}

And here is the output:

In my understanding, I feel like the last error (Exception in thread "main" com.rapidminer.operator.UserError: The dummy operator Decision Tree (replacing concurrency:parallel_decision_tree) cannot be executed.) seems to be the most severe one? Does anybody know how to fix this error? Or what I did wrong? Thank you for the help, highly appreciated.

Best regards

hi @Aldi I'm not an expert on the license differences between the package and compiling the open source version. You may be right about the concurrency decision tree. I know there's an old decision tree that is not parallelized that may be open source? Or you can use the Weka W-J48 decision tree from the Weka extension which should work.

And yes Naive Bayes is always a safe choice

hi @Aldi I'm sorry no one has chimed in here. Is this still an issue?

hi @sgenzer I think the problem is that I didn't have the required licenses to use the decision tree operator right? I changed it to Naive Bayes and it worked.
