PhysMani data for X-VLA
This dataset contains selected LeRobot data, metadata, and VelMap2D files
from the physmani and physmani_velmap2d directories used for X-VLA experiments. Upload is ongoing until upload_manifest.json
exists with complete: true. An incomplete upload is not a complete dataset.
Layout
physmani/: original metadata and archive files (large archives are split).physmani_velmap2d/: frame mapping and training normalization statistics.shards/physmani/xvla_lerobot*: converted LeRobot data.shards/physmani/trainandshards/physmani/val: legacy raw episode shards uploaded before the scope change; retained, but outside the completed dataset scope.shards/physmani_velmap2d/trainandshards/physmani_velmap2d/val: VelMap2D files.
Each part-*.tar under shards/ is an independent tar archive containing
paths starting with physmani/ or physmani_velmap2d/. Extract all shards
into the same destination directory to restore the original layout.
Original files are preserved byte for byte. Source archive copies are excluded by the scope change below.
For example, from the downloaded repository directory:
mkdir -p restored
find shards -name 'part-*.tar' -print0 | while IFS= read -r -d '' shard; do
tar -xf "$shard" -C restored
done
Copy the small metadata files from physmani/ and physmani_velmap2d/ into
their corresponding restored directories. Files ending in .part-00000,
.part-00001, etc. are ordered binary fragments of an existing source
archive, not independent archives. Reassemble each such archive with cat
in numeric filename order before extracting it. These archive copies are
optional if the corresponding raw-data shards have already been restored.
Metadata is preserved as originally used, including machine-specific paths.
Adjust those paths for your training machine. Older .bkup.json metadata
is retained for provenance; use the non-backup metadata for current inputs.
Runtime logs, upload-tool logs and caches are excluded.
The final upload manifest records the byte count and SHA-256 for each uploaded data file. Uploading this data does not establish model quality or equivalence between experiment variants.
Upload scope change (2026-10-02)
The owner stopped uploading raw physmani/train and physmani/val, and
excluded 20260619_robot_data_v8_balanced_train.tar.gz and
20260619_robot_data_v8_balanced_val.tar.gz. Previously uploaded raw shards
are retained; raw train is incomplete. complete: true in the final manifest
refers only to the revised scope, not to a complete raw episode dataset.
Converted LeRobot data, VelMap2D train/val, and metadata remain included.
physmani/xvla_data.tar is also excluded; it finished uploading before the
stop request was processed and was subsequently removed from the current repository revision.
