I cannot find join operator in Rapidminer studio 9.6
mansour_ebrahim
Dear All
I used to use join operator to create an excel file of prediction models, but now the previous models don't run as it cannot find Join operator. Do you know the equivalent of this in the new version?
Regards.

Hello,
The operator is there, under
Blending > Table > Joins
. It's one of the basic operations in RapidMiner Studio preparation, I doubt it will leave the basic tools.
All the best,
Rod.

Dear Rod
It's not. there are six operators there called: Append, set minus, intersect, union, superset and cartesian, but none of them is doing the same job as Join operator built in previous versions.

Hello
@mansour_ebrahim
That's strange, Did you try reinstalling the software?
mansour_ebrahim
No, just updated it to the latest version.

I experienced the same issue - there was no "Join" operator on the list. Additionally, connections were also lost. I could start RapidMiner only with extensions disabled, and the program didn't start if extensions were enabled. It happened after I cleared some tmp files on my machine.

So technically a bit of the functionality is delivered as an extension. If there is something which prevents extensions from being loaded, then you will just not get this functionality. This includes:
Join
Most Loop perators
A lot of ML (DT, GBT, RF, GLM)
Optimization operators
Everything auto model related
FP-Growth.
Maybe this helps to understand what's going on.
