I have been trying to use
F1 = make_scorer(fbeta_score, beta=1, labels = ['1', '2'], average='micro')
and F2
as the scoring parameter for logistic regression but glmnet throws the below error. It runs smoothly with scoring = 'accuracy', though. I tried to study the code but couldn't find a way to work with customized scores. Any help would be appreciated.
