I self-assigned #5666 and I was working on it... without success: https://github.com/huggingface/datasets/tree/fix-5666

I think your approach is the right one because installation of jax is not trivial...

Next time it would be better that you self-assign an issue before working on it, so that we avoid duplicate work... :sweat_smile: 

Oh sorry I forgot to self assign this time
