About how to organize the catalog of dataset?

Dear Author:
       Thanks for this code. I would like to ask you how organize the catalog of FLAIR datasets? I noticed that in the file with the path config/default.py there was a statement like _c.fla.test_split_path = src_path + 'data/flair_split/base/test.csv', How to download test.csv and plot.csv files, looking forward to your reply, thank you!
