Now I am trying to evaluate the classification with f1_score micro and macro but I am getting this error (on line 3) ValueError: Classification metrics can't handle a mix of multiclass-multioutput and multilabel-indicator targets and I dont know how I can solve it. This...

Label ambiguity and data complexity are widely recognized as major challenges in multi-label classification. Existing studies strive to find approximate representations concerning label semantics, however, most of them are predefined, neglecting the personality of instance-label pair. To circumvent this dra...
