Dummy

Synopsis

This operator is used as a placeholder for missing operators. Missing operators are those operators that are provided by an extension that is not installed in your RapidMiner setup.

Description

If you see this operator in a process, it means that the process requires an extension which is missing in your RapidMiner setup. Check the 'Manage Extensions' section to make sure that the required extension is installed and enabled. If the extension is not enabled, enable it and restart RapidMiner. When the required extension is enabled, the Dummy operator is replaced by the actual operator. The processes with a Dummy operator will not execute unless the appropriate extensions are enabled.
