2.3 Apply Message Passing On Part Of The Graph

If one only wants to update part of the nodes in the graph, the practice
|
|
is to create a subgraph by providing the IDs for the nodes to
|
|
include in the update, then call :meth:`~dgl.DGLGraph.update_all` on the
|
|
subgraph. For example:
|
|
|
|
.. code::
|
|
|
|
nid = [0, 2, 3, 6, 7, 9]
|
|
sg = g.subgraph(nid)
|
|
sg.update_all(message_func, reduce_func, apply_node_func)
|
|
|
|
This is a common usage in mini-batch training. Check :ref:`guide-minibatch` for more detailed
|
|
usages. |
