Adding attribute table image classification

Recently i’ve been able to apply fastai to benthic foraminifera taxonomy Background information on foraminifera… The results i’m getting is simply amazing. However, I remember in one of the lecture in part 1, someone asked the question about the possibility of adding attribute table from a spreadsheet before classification and @jeremy said it was possible in part two of the course.

I’m at that stage now when that knowledge will be helpful…

I’ll appriciate any pointer on how to do this or the video in part 2 that explains the concepts.
@sgugger, @muellerzr… any ideas ?
