[HELP NEEED] Perfomance Classfication Error
NewbieI want to see my performance model, my prediction is multi-classification type (0,1,2) but there is an error when it applies performance(Classification) operators "Performance(classification) cannot handle label."
Then I try to use the recommendation help solver. There is another error "label and prediction must be the same type but are nominal and integer, respectively. " then I try to change the performance(regression), and it works, but that is not what I want. Please help me to solve this thing, thank you.
Result:
Data type:
The first error using performance(classification):
The second error using performance(classification) with help me solve the problem:
