  Hello, my dear @varunm1
  

  
  

  I didn't have the same repository structure with me, but I simply removed that one, added a reader for the provided Excel file, added a "Set Role" before the multiplication of parameters, and the Cross Validations passed without problems.

  
  

  See attached process and a picture:

  
  

  

  
  

  Also the log indicates that the data didn't have a label before RapidMiner executed the three stooges cross validations. It actually switched from stratified sample to shuffled sample because it didn't have a way to reorganize the data in function of the labels.

  
  

  I marked the line that indicates it on your provided log file.
  

  
  

  
  

  
  

  Perhaps the process of changing the .ioobject containing the data wasn't saved?

  
  

  There are two easy fixes. One is to add the Set Role operator right after reading your data. The other one is opening your .ioobject with the Data Editor panel and make fixes accordingly.

  
  

  All the best,

  
  

  Rod.

  @varunm1,
  
  I tested by importing your Excel file (via "import data") and by setting Label as "label"  and changing Label type as "Binominal" during import and the process works fine...
  
  To see if, in your case, it is linked to Logistic Regression can you disable the CV associated to Logistic Regression in order
  to see if the other CV are executing without bugs ???
  
  Thanks 
  
  Regards,
