| # Downloading ALTER simulation artifacts |
|
|
| Models: https://huggingface.co/Berkeley-ICON-Lab/ALTER-models |
| Data and provenance: https://huggingface.co/datasets/Berkeley-ICON-Lab/ALTER-data |
| Code: https://github.com/labicon/ALTER/tree/e180a013e30d7b7c5478e029229ff9cd3154028e |
|
|
| The simulation code is merged into the public repository’s `main` branch. |
| The commands below pin the tested release revision for reproducible downloads. |
| Both artifact uploads are complete. release-manifest.json records immutable |
| artifact revisions and checksums. bundle-index.json and SHA256SUMS list this |
| repository’s artifact contents. The manifest pins the commits containing the |
| artifacts, which precede this documentation commit. |
|
|
| Check out the tested code revision and follow its [installation guide](https://github.com/labicon/ALTER/blob/e180a013e30d7b7c5478e029229ff9cd3154028e/documentation/release/installation.md): |
|
|
| ```bash |
| git clone https://github.com/labicon/ALTER.git |
| cd ALTER |
| git checkout e180a013e30d7b7c5478e029229ff9cd3154028e |
| ``` |
|
|
| Then, from the repository root run: |
|
|
| ```bash |
| python scripts/download_release.py --manifest release/manifest.json \ |
| --bundles simulation-models simulation-pretraining-data \ |
| simulation-adaptation-data simulation-provenance \ |
| --destination /path/to/ALTER-artifacts |
| python scripts/materialize_release.py --bundle-root /path/to/ALTER-artifacts \ |
| --output "$PWD/public-validation/inputs" |
| python scripts/validate_release_models.py --inputs "$PWD/public-validation/inputs" \ |
| --output "$PWD/public-validation/model-check.json" --training-smoke |
| ``` |
|
|
| Materialization requires all four bundles. It verifies hashes, relocates portable |
| artifact references and strictly validates derived checkpoint contracts. Direct |
| use of portable statistics before materialization is not supported. Only load |
| trusted pickle/PyTorch files. Short tests check functionality; they do not rerun |
| full training or establish paper success rates. Hardware v1 is documented separately in [hardware/v1/USAGE.md](hardware/v1/USAGE.md). |
|
|
| ## Hardware release code |
|
|
| Use [hardware v1 instructions](hardware/v1/USAGE.md) and the [tested code revision](https://github.com/labicon/ALTER/tree/a4919df35d703fafcf054717f8a53fd876b6a010). |
| Hardware and simulation use separate download directories and manifests. |
