I show the subprocess for Cross Validation with the error message Missing Values:



I show the process with the operator Replace Missing Values in preprocessing:



What is the way out here? Thanks for your time.

    Hi,
    you are retrieving the object before your cross validation again. This table is of course not changed by the operators you apply on the other copy.

    Martin, please clarify. You wrote: "you are retrieving the object before your cross validation again." You refer to the subprocess, correct?

    You wrote: "This table is of course not changed by the operators you apply on the other copy." You refer to the process, correct?

    If I get this right, I need to install another Remove Missing Values in the subprocess before Clustering, correct?
