Hi everyone,
I have a problem when I try to apply my machine learning model to a new dataset. Splunk send me this error: Error in 'apply' command: No valid fields to fit or apply model to.

But the feature variables are exactly the same in the training dataset and in the new dataset. Where does the problem come from?

Thank you for your answers.

Can you post more about the algorithm and the feature variables?
Can you post the search itself?
