How to export/convert fastai's internal data, like databunch or itemlist, to dataframe or narray or list?

1

Can I save databunch or itemlist into csv file? Or can I convert them into list or dataframe? I searched but failed to find anything.

2

I can do something like data.valid_ds.x.get(3) to have the item printed in string. But how can I get a narray or series out of it?

3

Similarily, how can I get learn.show_results() into a df? I am using the tabular sub-package.
