Class Member Number Requirement

[Archaeojp]

I am attempting to do classification in training a model using my own data following the steps laid out in the docs pages. Upon getting to a step for model score calculation, regardless of selection (Micro, Macro, or Weighted), the program fails saying "ValueError: n_splits=10 cannot be greater than the number of members in each class."

I could not find in the documentation anywhere notice of the required number of class members.
