| # LIBERO EDA Hosted Data |
|
|
| Immutable, browser-oriented data for the LIBERO EDA web application. |
|
|
| This repository contains: |
|
|
| - metadata for 130 Original LIBERO task families; |
| - browser replay metadata for 6,500 Original LIBERO demonstrations and 14,347 |
| LIBERO-Plus training trajectories; |
| - gzip-compressed Arrow IPC trajectory series; |
| - 128 x 128 WebP thumbnails; |
| - derived Original LIBERO MP4 and MuJoCo GLB assets; |
| - content-addressed LIBERO-Plus evaluation geometry and source textures, plus |
| numeric initial-state scene descriptors for all 10,030 evaluation conditions. |
|
|
| LIBERO-Plus training video is not duplicated. Replay manifests link to the |
| pinned `Sylvest/libero_plus_lerobot` revision. LIBERO-Plus evaluation |
| classification, BDDL, and init-state files are not copied; the application |
| loads definitions directly from |
| `sylvestf/LIBERO-plus@4976dc30028e805ff8094b55501d532c48fec182`. |
| The distributed scene descriptors were derived with official state index 0, |
| five zero actions, and a recorded environment/reset seed of 10,000. They retain |
| source-relative paths and SHA-256 provenance. If robosuite rejects a transient |
| constructor placement, the exporter advances the same seeded random stream |
| without reseeding, matching LIBERO's reset rejection sampling, and stops after |
| 100 attempts. |
| The scene manifest also pins the simulator asset dataset to |
| `Sylvest/LIBERO-plus@dd2bd61b7d9a6fef1abc52d606e983b41886a149`, records the |
| source archive SHA-256, and requires the exact 448,799-file extraction before |
| export. The extraction is matched to the official archive by path, byte size, |
| CRC, and a deterministic content tree SHA-256. Symlinks and incomplete or |
| modified extracts are rejected. |
| The pinned tree digest (`libero-plus-asset-tree-sha256/v1`) is |
| `6c4c2e638f6401304f01b2573c80af41b35b6d94838df71f6ab91f59468b7ecb`. |
|
|
| Original LIBERO video is displayed in its recorded source orientation. The |
| published LIBERO-Plus MP4 convention is rotated 180 degrees from raw LIBERO; |
| each replay manifest declares that convention and the Replay UI restores the |
| simulator orientation by default. The source pixels are not rewritten. |
| The public LIBERO-Plus files are one MP4 per episode, so hosted v2 manifests |
| use a zero-based interval from `0` to `state_count / 20`. The one-way v1-to-v2 |
| migration verifies the older chunk-global interval length before normalizing |
| it; video bytes are neither copied nor modified. |
|
|
| Evaluation scenes are interactive initial states, not screenshots, videos, or |
| successful trajectories. Geometry is shared per Original LIBERO source task, |
| and textures are deduplicated by content hash. |
|
|
| `manifest.json` is the small browser entry point for schema, counts, and |
| provenance. It pins `integrity/artifacts.json`, which records every distributed |
| file's byte size and SHA-256 value. Both are written only after a complete |
| export. |
