        <p>Dear scikit experts,</p>
        <p><br>
        </p>
        <p>I did as you suggested, but it is not exactly what I would
          like to do ( I also read this:

        <p>Perhaps I should ask my question in another way: it is
          possible to split the nested cv folds just once? It seems to
          me that this is not possible, do you have any hints?</p>

    Not sure I understand your question.<br>
    You can do a single split by using ShuffleSplit(n_splits=1) for
    example.<br>
