In my process , I connected Read Excel with Validation which contains ( the nestled operator  SVM  and apply model)


When I run the model , it says ,

" Input example set has no attributes.Learning methods...". Anyone seen this before ?  ???

    Hi,
    yes, this occurs if your example set is empty. Please select the read excel operator, and mark it with a break point. More information about breakpoints can be found in the manual.
    If you have done so, the process will stop and you can take a look at the results of the import. Might be, it is simply empty :) Then you have to correct the settings of the operator.

    By the way: Predicting Time series cannot be validated with a X-Validation in a meaningful way, because then inside a training fold is information about the future...
