| # ReInterHand shared-v1.0 — reproduction and review | |
| Use Python 3.12 on Linux (the archived production converters use POSIX locks, | |
| symlinks and archive streaming). No GPU is required. Two dataset workers and | |
| two FFmpeg threads per worker are the production limits; numerical libraries | |
| are limited to one thread by `run.py`. Leave at least 400 GB free. | |
| ## Install | |
| Create a Python 3.12 virtual environment **outside** shared-v1.0: | |
| ```sh | |
| python3.12 -m venv ../runtime-env | |
| . ../runtime-env/bin/activate | |
| python -m pip install -r script/requirements-lock.txt | |
| ffmpeg -version | |
| ffprobe -version | |
| ``` | |
| Install FFmpeg/ffprobe separately (production ReInterHand used FFmpeg 6.1.1). | |
| The package lock records direct Python dependencies, not a full OS image. | |
| Acquire MANO v1.2 LEFT/RIGHT pickle files under the MANO license; they are not | |
| redistributed here. Put them in the `models` directory in `script/config.json`. | |
| For ReInterHand that directory must be `<runtime>/models`. Install dependencies | |
| in the activated environment; the optional `packages` path allows reuse of | |
| the existing server installation. It may point to a nonexistent directory | |
| when using the virtual environment. Paths in config are relative to the dataset | |
| root (the parent of shared-v1.0), or may be absolute. Place raw at `<root>/raw`. | |
| ## Commands (from shared-v1.0) | |
| ```sh | |
| python script/run.py checksums | |
| python script/run.py preflight | |
| python script/run.py inventory | |
| python script/run.py validate | |
| python script/run.py validate --tensors | |
| python script/run.py validate --tensors --media | |
| python script/run.py review | |
| ``` | |
| `validate` reads every view's metadata, declared references and complete frame | |
| mapping. `--tensors` also loads component data/valid tensors, checks T, dtype, | |
| finite valid values and camera rotations. `--media` decodes all MKV streams | |
| to count frames and check dimensions; it can take many hours. Neither mode | |
| claims source pixel equivalence or independent official digest verification. | |
| For machine reports use `python script/validate_release.py --output ../tmp/check`. | |
| `review` reads the current data and writes a new fixed-seed complete-sequence | |
| review to config `review_output`; an existing output is rejected to preserve | |
| earlier review evidence. New reports start pending and require new human review. | |
| ## Reproduce conversion in a fresh root | |
| Copy this script directory into a fresh `<root>/shared-v1.0/script`, configure | |
| the models and put the verified raw at `<root>/raw`. Pilot and production | |
| should use separate output roots. After explicit pilot approval: | |
| ```sh | |
| python script/run.py pilot --sequence '<capture ID>' --segment <action> | |
| python script/run.py full | |
| ``` | |
| The safe handoff entry refuses conversion into a populated data directory. | |
| For an interrupted run, investigate first, retain its tmp checkpoints and use | |
| the archived converter directly with the same arguments, input, script and | |
| configuration. Do not remove locks without checking the actual process. | |
| ReInterHand historical checkpoints do not bind every script/input change; | |
| do not reuse them after changing converter logic. Existing production data | |
| was not reconverted during this documentation repair. | |
| ## File responsibilities | |
| - `run.py`: simple release-local CLI, config loading, CPU limits and guards. | |
| - `config.json`: paths, resources, deterministic review seed and optional partition. | |
| - `preprocess_*.py`: archived dataset conversion implementation; retained filenames | |
| preserve imports and production provenance. | |
| - `validate_release.py`: independently rereads final files; no data writes. | |
| - `render_*`: full-sequence review renderers, called by `run.py review`. | |
| - `requirements-lock.txt`: pinned direct Python dependencies. | |
| - `checksums.json`: all formal script file SHA256 values, excluding itself. | |
| Publication is deliberately external to this reproduction bundle. This bundle | |
| has no upload command. Existing fixed-commit | |
| verification evidence is in `../doc/validation/publication/`; a future release | |
| must get authorization and create a new manifest before publication. | |
| Raw is read-only. Scratch, logs, locks and model files stay outside shared-v1.0. | |
| See `../doc/RAW_MAPPING.md` for time semantics, splits and modality mappings. | |
| For distributed reproduction, set captures_file to captures-iipl100.txt or captures-iipl126.txt, never both on one worker. The two lists are disjoint and cover all 10 captures. Set partition to the matching label for sampling. | |
