Lerobot code like the ones inside data_loader are deprecated.

[Bombardelli]

Also lerobot data_loader is not working anymore inside env with python 3.11.

[Alex-gift-hit]

openpi env use the lerobot 0.1.0, lerobot-dataset v2.1. It can work properly at lerobot dataset V2.1.
but not the lerobotdataset v3.0 with lerobot v0.5.1.
