tf.graph_util.import_graph_def(
    graph_def,

    return_elements=None,
    name=None,

Used in the guide:

• Migrate your TensorFlow 1 code to TensorFlow 2

Warning: SOME ARGUMENTS ARE DEPRECATED: (op_dict). They will be removed in a future version. Instructions for updating: Please file an issue at https://github.com/tensorflow/tensorflow/issues if you depend on this feature.

This function provides a way to import a serialized TensorFlow GraphDef protocol buffer, and extract individual objects in the GraphDef as tf.Tensor and tf.Operation objects. Once extracted, these objects are placed into the current default Graph. See tf.Graph.as_graph_def for a way to create a GraphDef proto.

Args:

• graph_def: A GraphDef proto containing operations to be imported into the default graph.
• input_map: A dictionary mapping input names (as strings) in graph_def to Tensor objects. The values of the named input tensors in the imported graph will be re-mapped to the respective Tensor values.
• return_elements: A list of strings containing operation names in graph_def that will be returned as Operation objects; and/or tensor names in graph_def that will be returned as Tensor objects.
• name: (Optional.) A prefix that will be prepended to the names in graph_def. Note that this does not apply to imported function names. Defaults to "import".
• op_dict: (Optional.) Deprecated, do not use.
• producer_op_list: (Optional.) An OpList proto with the (possibly stripped) list of OpDefs used by the producer of the graph. If provided, unrecognized attrs for ops in graph_def that have their default value according to producer_op_list will be removed. This will allow some more GraphDefs produced by later binaries to be accepted by earlier binaries.

Returns:

• A list of Operation and/or Tensor objects from the imported graph, corresponding to the names in return_elements, and None if returns_elements is None.

Raises:

• TypeError: If graph_def is not a GraphDef proto, input_map is not a dictionary mapping strings to Tensor objects, or return_elements is not a list of strings.
• ValueError: If input_map, or return_elements contains names that do not appear in graph_def, or graph_def is not well-formed (e.g. it refers to an unknown tensor).
