Imports the graph from graph_def into the current default Graph. (deprecated arguments)
tf.graph_util.import_graph_def(
graph_def,
input_map=None,
return_elements=None,
name=None,
op_dict=None,
producer_op_list=None
)
Used in the notebooks
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).
