How do you Trouble Shoot "Object retrieval not possible"

tmarcinelli

Hello,

Need Trouble Shooting help with  "Object retrieval not possible" error.

Going thru RapidMiner tutorials... doing video tutorial named:  "Automated Model Selection & Optimization"

 

I have done everything in video, but get error on When I run, the "RECALL" object says no object with the name I named was found (I named 3 Recall objects per tutorial)

... I have poured over correct process per sample downloaded process, but can see no difference... Yet sample runs, mine comes up with error.

I have included my process XML file.  Would appreciate any help.

 

Thank you,

Tony

Hi tmarcinelli,

 

there are two differences between the instructor process and your process:

• The Recall operators in the instructor process have not selected remove from store but you have. The subprocess in Compare ROCs is executed more than once so the removal prevents from finding the object the second time.
• The outer Optimize Parameter operator in the instructor process has not selected enable parallel execution but you have. That this must be unselected might be a bug, I will check this.

When changing these two parameter settings, your process works for me.
