CuGraphModule
The relational graph convolutional operator from the “Modeling Relational Data with Graph Convolutional Networks” paper.
CuGraphRGCNConv
is an optimized version ofRGCNConv
based on thecugraph-ops
package that fuses message passing computation for accelerated execution and lower memory footprint.- forward(x: Tensor, edge_index: EdgeIndex, edge_type: Tensor, max_num_neighbors: Optional[int] = None) Tensor [source]
Runs the forward pass of the module.
- Parameters:
x (torch.Tensor) – The node features.
edge_index (EdgeIndex) – The edge indices.
edge_type (torch.Tensor) – The edge type.
max_num_neighbors (int, optional) – The maximum number of neighbors of a target node. It is only effective when operating in a bipartite graph.. When not given, the value will be computed on-the-fly, leading to slightly worse performance. (default:
None
)
- Return type:
