"""Get node map from meta_graph_def.
This is designed to extract structures of the following form from the
meta_graph_def collection_def:
prefix/key
key1
key2
key3
prefix/suffix_a
node1
node2
node3
prefix/suffix_b
node4
node5

which will become a dictionary:
{
key1 : {suffix_a: node1, suffix_b: node4}
key2 : {suffix_a: node2, suffix_b: node5}
key3 : {suffix_a: node3, suffix_b: node6}
}.
Keys must always be bytes. Values can be any supported CollectionDef type
(bytes_list, any_list, etc)
Args:
meta_graph_def: MetaGraphDef containing the CollectionDefs to extract the
structure from.
prefix: Prefix for the CollectionDef names.
node_suffixes: The suffixes to the prefix to form the names of the
CollectionDefs to extract the nodes from, e.g. in the example described
above, node_suffixes would be ['suffix_a', 'suffix_b'].
Returns:
A dictionary of dictionaries, as described in the example above.
Raises:
ValueError: The length of some node list did not match length of the key
list.
