Decision Tree Operator is Missing

Goh

I could not find the classic Decision Tree operator. Error Message is attached.

What happened to the usual operator that is used in previous textbook examples and RapidMiner sample processes? Do I need a plugin? How do I get the operator working again?

Appreciate your help with the details. Thank you.

Hi @Goh ,

which version of RapidMiner are using?

In RapidMiner there is of course an implementation of the classic version of the Decision Tree. The error you see, is that inside the process you try to open can't find the latest version of it.

Best,
David

I am using RapidMiner 9.6.
My laptop uses Windows 64 bit.

When I downloaded and used RapidMiner 9.6 with the Windows 64 bit version, this error keeps popping out. However, when I uninstalled and re-installed using the RapidMiner Windows 32 bit version, this error no longer appears.

Anything wrong with the RapidMiner installer files?

Just run the 64 bit installer twice, sometimes the installer can't clean up the old installation properly if you switch between 32 and 64 bit.

I have run the 64 bit installer more than 5 times before. But the same problem persists.
