| | `catalog/` | Primary scene catalog plus all scene-asset entries | Geography and selective downloads | | |
| The primary benchmark uses 60 scenes. Adaptation adds two scene IDs and reuses | |
| tokyo_01; five additional scene packages are supplementary geometry, not extra | |
| primary benchmark training scenes. Counts must not be mixed. | |
| ## Minimal download and training | |
| Run `examples/download_dataset.py --destination citydeploy_data`. This fetches | |
| the lightweight core and its scene tensors, not the large Radio Maps or meshes. | |
| The companion repository accepts the resulting directory directly: | |
| ```console | |
| citydeploy train --model hpem --dataset-root citydeploy_data/core/urban_multicity --scene-root citydeploy_data/scenes --device cuda | |
| ``` | |
| Use `--model regressor`, `--model in` or `--model nri` for the other models. | |
| Install the companion code and select training budgets before a full experiment. | |
| ## Optional physical assets and maps | |
| ```console | |
| python examples/download_dataset.py --destination citydeploy_data --with-scenes --scenes london_01 | |
| python examples/download_dataset.py --destination citydeploy_data --with-radio-maps --scenes london_01 | |
| python examples/download_dataset.py --destination citydeploy_data --adaptation | |
| ``` | |
| The scene archives unpack under `citydeploy_data/scenes`. Available maps unpack | |
| under the primary core's `radio_maps` directory, matching row `rich_map_path` | |
| references. Archives remain cached after extraction; plan disk space for both | |
| archives and extracted maps. A request for all maps transfers approximately | |
| 115 GB before extraction. No missing map is synthesized. | |
| The downloader pins a single Hub commit for each invocation, validates file | |
| checksums, rejects unsafe archive paths and refuses to replace a different | |
| existing file. Record its printed revision with experiments. Pass `--revision` | |
| to reproduce a fixed release. Interrupted downloads can resume through the Hub | |
| cache; interrupted archive extraction leaves a visible `.partial` file for | |
| inspection. Remove only that incomplete output before retrying. | |
| ## Archive and licensing scope | |
| TAR owner fields are empty and modification times are fixed to zero. NPZ ZIP | |
| members use fixed synthetic timestamps and have no comments or extra fields. | |
| No model weights, experiment logs, author-machine paths or satellite imagery | |
| are included. See the component-specific terms in `LICENSE.md`. | |
| Source feature extracts preserve geometry and selected physical semantic tags. | |
| Free-text/contact tags and acquisition/QA run metadata are omitted from the public | |
| export. Stored meshes, numerical scene channels and simulation values remain the | |
| reference inputs and outputs; regenerating geometry from live map services is not | |
| equivalent to loading these archived assets. | |
