HuggingFaceFW/fineweb-2 · Number of rows not available for all configs.

Hi, I've noticed that some configs are missing their sizes. I'm trying to query the API with the https://datasets-server.huggingface.co/size?dataset=HuggingFaceFW/fineweb-2 endpoint, but this also doesn't return the size (number of rows) for all configs.

I need this information because I want to properly sample different languages for multilingual training (and filter low-resource languages without accidentally removing high-resource languages such as Filipino) without downloading the entire dataset (config=True).

EDIT: I just realized the complete list is available in the README, but it would be nice to be able to get it programmatically.
