dgl.block_to_graph

dgl.block_to_graph(block)[source]

Convert a message flow graph (MFG) as a DGLBlock object to a DGLGraph.

DGL will rename all the source node types by suffixing with _src, and all the destination node types by suffixing with _dst.

Features on the returned graph will be preserved.

Parameters:: block (DGLBlock) – The MFG.
Returns:: The graph.
Return type:: DGLGraph

Examples

>>> block = dgl.create_block({
...     ('A', 'AB', 'B'): ([1, 2, 3], [2, 1, 0]),
...     ('B', 'BA', 'A'): ([2, 1], [2, 3])})
>>> g = dgl.block_to_graph(block)
>>> g
Graph(num_nodes={'A_src': 4, 'B_src': 3, 'A_dst': 4, 'B_dst': 3},
      num_edges={('A_src', 'AB', 'B_dst'): 3, ('B_src', 'BA', 'A_dst'): 2},
      metagraph=[('A_src', 'B_dst', 'AB'), ('B_src', 'A_dst', 'BA')])
