Robotics · dataset migration v2.1 → v3

lerobot-dataset-migrate

A migration demonstrator that measures preservation of frames, features, episodes, tasks, metadata counters, and index continuity instead of treating a completed copy as success.

The problem

The real migration question is not “did it run?” but “did anything disappear?”

A format change needs explicit validation of the content and indexing that arrived on the other side.

The money shot

Clean data passes; deliberately broken data fails loudly

Validation checks preservation and continuity rather than inferring success from the migration process returning.

Honest limitations

The sample models the documented formats with synthetic datasets. It does not establish compatibility with every real dataset or prove downstream model performance.
