Apr 1, 2025April 2025 — StanfordVL/OmniGibson: Implemented comprehensive data integrity and asset-tracking improvements in the DVC-powered data pipeline. The work focused on metadata accuracy (MD5 hashes and file sizes) across multiple batches, updates to legacy batch metadata, and asset tooling changes. Reproducibility was strengthened via updates to the DVC lockfile, and the pipeline was made more robust with the addition of an rtree dependency and a type-hint correction in _compute_relative_poses_torch to improve code safety. These changes enhance data reliability, traceability, and reproducibility, reducing downstream debugging and enabling more stable experimentation.
