Instead of the check here, i would maybe change it to raising a
ValueError
in the top of the function if self.k_features is not in {'best', 'parsimonious'} and self.early_stop_rounds. This way the user is aware, and we only have to perform the check once.There was a problem hiding this comment.

@rasbt Do you prefer having this check on top of
fit
function or during initialization?There was a problem hiding this comment.

Ahh, totally lost track and missed your comment! Sorry! Regarding your question, I think
fit
might be better to keep it more consistent with scikit-learn behavior.
