Question: Data license discrepancy between README (CC BY 4.0) and dataset cards (Apache-2.0) #150

Hi, and thank you for releasing LIBERO.

The README states the datasets are released under CC BY 4.0, but the HuggingFace dataset cards for both the source datasets (yifengzhu-hf/LIBERO-datasets) and the LeRobot projection (lerobot/libero) are labeled Apache-2.0.

Could you clarify:

1. Which license governs the datasets?
2. Can the dataset-card labels be traced to an authorization from the upstream licensor?

Context: we only need this clarified for internal, non-commercial research evaluation use. Happy to provide more detail if useful.
