Non-nominal label: the lavel attribute must be nominal
i encountered a problem that i'm unable to solve.
When i do cross validation for KNN i get an error pop for the function Performance (classification): " Non-nominal label: the lavel attribute must be nominal"
I don't understand why i get this pop up since the data is all nomimal before the KNN function?
Also when i use the function " polynominal to binominal" i get below errorNumerical label not supported
