WebThe # computation flow underlying a DAG can be executed in one sweep, by # calling ``prop_flows``. # # ``prop_flows`` accepts a list of UDFs. The code below defines node update UDFs # for each layer and computes a simplified version of GCN with neighbor sampling. # apply_node_funcs = [ lambda node : { 'h' : layers [ 0 ] (node) [ 'activation ... WebFeb 27, 2024 · The metapath2vec example is following DGL nightly build, which only recently introduced various sampling methods on heterogeneous graphs in dgl.sampling module.
