tf.contrib.receptive_field.get_compute_order

Computes order of computation for a given CNN graph.

tf.contrib.receptive_field.get_compute_order(
    graph_def, input_node_name='', input_node_size=None
)

Optionally, the function may also compute the input and output feature map resolutions at each node. In this case, input_node_name and input_node_size must be set. Note that if a node's op type is unknown, the input and output resolutions are ignored and set to None.

Args
graph_def	GraphDef object.
input_node_name	Name of node with fixed input resolution (optional). This is usually the node name for the input image in a CNN.
input_node_size	2D list of integers, fixed input resolution to use (optional). This is usually the input resolution used for the input image in a CNN (common examples are: [224, 224], [299, 299], [321, 321]).

Returns
node_info	Default dict keyed by node name, mapping to a named tuple with the following fields: order: Integer denoting topological order; node: NodeDef for the given node; input_size: 2D list of integers, denoting the input spatial resolution to the node; output_size: 2D list of integers, denoting the output spatial resolution of the node.
name_to_node	Dict keyed by node name, each entry containing the node's NodeDef.
