Send message from the node(s) to their successors and update them.

Optionally, apply a function to update the node features after receive.

In the graph store, all updates are written inplace.

Parameters

  • u (int, iterable of int, or tensor) – The node(s) to push messages out.

  • message_func (callable, optional) – Message function on the edges. The function should be an Edge UDF.

  • reduce_func (callable, optional) – Reduce function on the node. The function should be a Node UDF.
