    are you sure that all performances going in are not NAN or Inf?

    1- Input performances are precision and recall which are shown correctly when connected separately to the output.

    2- The exact same setup works well for 10-fold cross-validation, but this happens when doing LOO or let's say 50-fold CV. (dataset size is around 300-400)
