- class S3DIS(root: str, test_area: int = 6, train: bool = True, transform: Optional[Callable] = None, pre_transform: Optional[Callable] = None, pre_filter: Optional[Callable] = None, force_reload: bool = False)[source]
Bases:
InMemoryDataset
The (pre-processed) Stanford Large-Scale 3D Indoor Spaces dataset from the “3D Semantic Parsing of Large-Scale Indoor Spaces” paper, containing point clouds of six large-scale indoor parts in three buildings with 12 semantic elements (and one clutter class).
- Parameters:
root (str) – Root directory where the dataset should be saved.
test_area (int, optional) – Which area to use for testing (1-6). (default:
6
)train (bool, optional) – If
True
, loads the training dataset, otherwise the test dataset. (default:True
)transform (callable, optional) – A function/transform that takes in an
torch_geometric.data.Data
object and returns a transformed version. The data object will be transformed before every access. (default:None
)pre_transform (callable, optional) – A function/transform that takes in an
torch_geometric.data.Data
object and returns a transformed version. The data object will be transformed before being saved to disk. (default:None
)pre_filter (callable, optional) – A function that takes in an
torch_geometric.data.Data
object and returns a boolean value, indicating whether the data object should be included in the final dataset. (default:None
)force_reload (bool, optional) – Whether to re-process the dataset. (default:
False
)
