Hello,

I got this error while trying to use SequentialFeatureSelector. Could you please help take a look in the underlying codes? Thanks a lot

sfs = SFS(LogisticRegression(), k_features=5, #number of features to select forward = True, #rolling forward selection floating=False, # No floating selection scoring='accuracy', verbose=5, cv=5 ).fit(X_train,y_train)
