cross validation and step_smote(): smote_impl Not enough observations

[Steviey]

Using recipe >> themis::step_smote() produces this, while cross validation...

x Fold6: preprocessor 1/1: Error in smote_impl():
! Not enough observations of '4' to perform SMOTE.

How can I avoid it? The data is already stratisfied.

Hello @Steviey 👋

You are getting this error because there are less than neighbors + 1 observations in class with the name '4'. I'm afraid that there isn't much to do in this situations. That isn't a lot of observations in a minority class.
