Options for saving to SavedModel.
tf.saved_model.SaveOptions(
namespace_whitelist=None,
save_debug_info=False,
function_aliases=None,
experimental_io_device=None,
experimental_variable_policy=None,
experimental_custom_gradients=True,
experimental_image_format=False,
experimental_skip_saver=False
)
This function may be used in the options
argument in functions that
save a SavedModel (tf.saved_model.save
, tf.keras.models.save_model
).
Args |
namespace_whitelist
|
List of strings containing op namespaces to whitelist
when saving a model. Saving an object that uses namespaced ops must
explicitly add all namespaces to the whitelist. The namespaced ops must
be registered into the framework when loading the SavedModel. If no
whitelist is provided, all namespaced ops will be allowed.
|
save_debug_info
|
Boolean indicating whether debug information is saved. If
True, then a debug/saved_model_debug_info.pb file will be written with
the contents of a GraphDebugInfo binary protocol buffer containing stack
trace information for all ops and functions that are saved.
|
function_aliases
|
Python dict. Mapping from string to object returned by
@tf.function. A single tf.function can generate many ConcreteFunctions.
If a downstream tool wants to refer to all concrete functions generated
by a single tf.function you can use the function_aliases argument to
store a map from the alias name to all concrete function names. E.g. >>>
class Adder(tf.Module): ... @tf.function ... def double(self, x):
... return x + x >>> model = Adder() >>>
model.double.get_concrete_function( ... tf.TensorSpec(shape=[],
dtype=tf.float32, name="float_input")) >>>
model.double.get_concrete_function( ... tf.TensorSpec(shape=[],
dtype=tf.string, name="string_input")) >>> options =
tf.saved_model.SaveOptions( ... function_aliases={'double':
model.double}) >>> tf.saved_model.save(model, '/tmp/adder',
options=options)
|
experimental_io_device
|
string. Applies in a distributed setting.
Tensorflow device to use to access the filesystem. If None (default)
then for each variable the filesystem is accessed from the CPU:0 device
of the host where that variable is assigned. If specified, the
filesystem is instead accessed from that device for all variables. This
is for example useful if you want to save to a local directory, such as
"/tmp" when running in a distributed setting. In that case pass a device
for the host where the "/tmp" directory is accessible.
|
experimental_variable_policy
|
The policy to apply to variables when
saving. This is either a saved_model.experimental.VariablePolicy enum
instance or one of its value strings (case is not important). See that
enum documentation for details. A value of None corresponds to the
default policy.
|
experimental_custom_gradients
|
Boolean. When True, will save traced
gradient functions for the functions decorated by tf.custom_gradient .
Defaults to True .
|
experimental_image_format
|
New (highly) experimental format that is
capable of saving models larger than the 2GB protobuf limit. Enabling
this option will likely break compatibility with downstream consumers.
This option is currently disabled in OSS.
|
experimental_skip_saver
|
If True, will prevent SavedModel from creating
its native checkpointing ops - this is for models that do not use
SavedModel's native checkpointing functionality to avoid the costs
associated with creating and serializing those ops.
