| # RoboDojo Assets — verified transport shards |
|
|
| This public dataset is a byte-preserving transport repack of `Assets/` from |
| [`RoboDojo-Benchmark/RoboDojo`](https://huggingface.co/datasets/RoboDojo-Benchmark/RoboDojo), pinned at source commit |
| `aada55a7a58b520a2004b9db02e884144b6e83e7`. It reduces 15,335 source files to 11 independently downloadable and |
| restorable `tar.zst` shards. No payload file was changed. |
|
|
| 这是 RoboDojo `Assets/` 的公开传输分片：固定源 commit、减少小文件数量、每片可独立下载/重试， |
| 完整复原后会逐文件做 SHA-256 校验。 |

|
|
| `SHA256SUMS` verifies the 11 transport archives. `FILES.sha256` verifies every restored |
| source file. `MANIFEST.json` records exact counts, sizes, paths, and full hashes. |
|
|
| ## Download with low external concurrency |
|
|
| Install the current Hugging Face CLI, then choose one or two workers. Pin `--revision` |
| to a full commit SHA in production. |
|
|
| ```bash |
| hf download didfd/robodojo-assets-packed \ |
| --repo-type dataset \ |
| --revision <FULL_PACKED_REPO_COMMIT_SHA> \ |
| --local-dir /path/to/robodojo-assets-packed \ |
| --max-workers 2 |
| ``` |
|
|
| If the company importer accepts file URLs only, import the 11 files under `data/` plus |
| `MANIFEST.json`, `SHA256SUMS`, `FILES.sha256`, `lists/`, and `restore.py`. With concurrency |
| 1, only one ~3.7 GB object is active at a time; a failed transfer only retries that shard. |
|
|
| ## Restore and verify |
|
|
| Python 3.9+, `zstd`, and Linux with `/proc/self/fd` plus `O_NOFOLLOW` support are required. |
| The restore tool validates all metadata, archive hashes, and structured tar headers before |
| creating the output. It rejects links, sparse files, devices, FIFOs, non-canonical paths, |
| duplicates, and cross-shard path conflicts. Each shard is extracted into an isolated private |
| staging directory; only a fully hashed tree is atomically published as `Assets/`. |
|
|
| ```bash |
| python3 restore.py \ |
| --repo-dir /path/to/robodojo-assets-packed \ |
| --output-dir /path/to/restored \ |
| --workers 4 \ |
| --hash-workers 16 |
| ``` |
|
|
| Success ends with `RESTORE VERIFIED`; the restored root is |
| `/path/to/restored/Assets/`. If `Assets/` already exists, `--force` builds and verifies a |
| fresh tree first, atomically replaces the old tree, and preserves the old tree as |
| `Assets.backup.<random-id>`; it does not perform an in-place overwrite. Atomic replacement |
| requires filesystem support for Linux `RENAME_EXCHANGE`; if unavailable, `--force` fails |
| without modifying the existing tree. |
