torch_geometric.transforms.Constant
- class Constant(value: float = 1.0, cat: bool = True, node_types: Optional[Union[str, List[str]]] = None)[source]
Bases:
BaseTransform
Appends a constant value to each node feature
x
(functional name:constant
).- Parameters:
value (float, optional) – The value to add. (default:
1.0
)cat (bool, optional) – If set to
False
, existing node features will be replaced. (default:True
)node_types (str or List[str], optional) – The specified node type(s) to append constant values for if used on heterogeneous graphs. If set to
None
, constants will be added to each node featurex
for all existing node types. (default:None
)
