What this does

Uses original transformers package instead of opentau-transformers (branch fix/lerobot-openpi)

How it was tested

Did a training run on libero and no regression was found

How to checkout & try? (for the reviewer)

opentau-train --config_path=configs/examples/pi05_training_config.json

Is the src/opentau/utils/transformers_patch.py imported anywhere? It doesn't look like the patch would have taken effect.

It is imported here:

from opentau.utils import transformers_patch # noqa: F401

The eval using TensorAuto/tPi0.5-libero checkpoint is performing as expected.
