Why doesn't my pandas rolling().apply() work when the series contains collections?

Question

I\'ve got a pandas series in which each cell is a tuple. I\'m trying to do a rolling().apply() on that series, and the function I\'m trying to apply is never getting called

Answer 1

This will not work because the pandas.DataFrame.rolling function returns a Window or Rolling sub-classed for the particular operation while pandas.DataFrame.apply Applies function along input axis of DataFrame. As mentioned by ayhan, in this post.
