Thanks for adding this datasets. This looks all good so far :)

I'm wondering if we should load the actual squad_v2 data or not. It would be more convenient to have the data from squad_v2 and in the squadformat. WDYT ?

Sounds great! It'll make things easier for the user while accessing the dataset. I'll make some changes to the current file then.

I've updated with the suggested changes. Updated the README, YAML tags as well (not sure of Size category tag as I couldn't pass the path of dataset_infos.json for this dataset)

Nice thank you ! :D

I added my final comments. My only concern is just about some part of the code that should be moved in _generate_examples rather than _split_generators.

But apart from that, the code and the dataset card are all good !

Perfect thanks :)
