Raise Error when split dataset

[NoobAnA]

I have get an error when running the code:

splits_all = biolab_utilities.data_per_id_and_date(records_filtered_by_subject, n_splits=3)

raise ValueError("Wrong train size: train_size={:d},test_size={:d} out of {:d}".
ValueError: Wrong train size: train_size=1,test_size=0 out of 1

i think the feature data is not sent to the split function. How can i fix this problem?
Thanks for helping.
