tf.graph_util.convert_variables_to_constants(
    sess, input_graph_def, output_node_names, variable_names_whitelist=None,
    variable_names_blacklist=None
)

If you have a trained graph containing Variable ops, it can be convenient to convert them all to Const ops holding the same values. This makes it possible to describe the network fully with a single GraphDef file, and allows the removal of a lot of ops related to loading and saving the variables.

Args
sess	Active TensorFlow session containing the variables.
input_graph_def	GraphDef object holding the network.
output_node_names	List of name strings for the result nodes of the graph.
variable_names_whitelist	The set of variable names to convert (by default, all variables are converted).
variable_names_blacklist	The set of variable names to omit converting to constants.

Returns
GraphDef containing a simplified version of the original.
