Note for reviewers: The relevant changes reside in P3.py and io_utils.py. The rest are formatting changes made to be aligned with the datasets formatting style.
Awesome ! Just one nit: it seems that https://huggingface.co/datasets/bigscience/P3/blob/refs%2Fpr%2F11/tasks_splits_and_features.py is stored as an LFS file, which makes it not viewable in the UI
Regarding the dependencies - it seems that one just needs to pip install google to have this dataset work right ?
protobuf is the name of the dependency (pip install protobuf). I added a From: comment to the import to improve the error message when the lib is not installed. Since Tensorflow depends on it, the viewer should work out of the box.
Awesome ! LGTM then :)
