Return the list of graphs in this batch.
Parameters: graph (DGLGraph) – The batched graph. Returns: A list of
DGLGraphobjects whose attributes are obtained by partitioning the attributes of the
graph. The length of the list is the same as the batch size of
Return type: list
Unbatching will break each field tensor of the batched graph into smaller partitions.
For simpler tasks such as node/edge state aggregation, try to use readout functions.
