pylibcugraphops.operators.agg_concat_e2n_fwd = <nanobind.nb_func object>#
Computes the forward pass for simple aggregation using edge features in an

edge-to-node reduction (e2n) on a graph while concatenating the original features of output nodes at the end (agg_concat).

output_embeddingdevice array type

Device array containing the output node embeddings. Shape: (graph.n_dst_nodes, dim_node + dim_edge).

input_edge_embeddingdevice array type

Device array containing the input edge embeddings. Shape: (n_edges, dim_edge).

input_node_embeddingdevice array type

Device array containing the input node embeddings to be concatenated. Shape: (graph.n_dst_nodes, dim_node).

graphopaque graph type

The graph used for the operation.

aggregation_operationAggOp, default=AggOp.Sum

The kind of aggregation operation.

output_extrema_locationdevice array type | None

Device array containing the location of the min/max embeddings. This is required for min/max aggregation only, and can be None otherwise. Shape: (graph.n_dst_nodes, dim_edge) if set.

stream_idint, default=0

CUDA stream pointer as a python int.
