This class exports the serving graph and checkpoints at the end.
Inherits From: Exporter
tf.estimator.FinalExporter(
name, serving_input_receiver_fn, assets_extra=None, as_text=False
)
This class performs a single export at the end of training.
Args |
name
|
unique name of this Exporter that is going to be used in the
export path.
|
serving_input_receiver_fn
|
a function that takes no arguments and returns
a ServingInputReceiver .
|
assets_extra
|
An optional dict specifying how to populate the assets.extra
directory within the exported SavedModel. Each key should give the
destination path (including the filename) relative to the assets.extra
directory. The corresponding value gives the full path of the source
file to be copied. For example, the simple case of copying a single
file without renaming it is specified as
{'my_asset_file.txt': '/path/to/my_asset_file.txt'} .
|
as_text
|
whether to write the SavedModel proto in text format. Defaults to
False .
|
Raises |
ValueError
|
if any arguments is invalid.
|
Attributes |
name
|
Directory name.
A directory name under the export base directory where exports of
this type are written. Should not be None nor empty.

Methods
export

export(
estimator, export_path, checkpoint_path, eval_result, is_the_final_export
)
Exports the given Estimator
to a specific format.
Args |
estimator
|
the Estimator to export.
|
export_path
|
A string containing a directory where to write the export.
|
checkpoint_path
|
The checkpoint path to export.
|
eval_result
|
The output of Estimator.evaluate on this checkpoint.
|
is_the_final_export
|
This boolean is True when this is an export in the
end of training. It is False for the intermediate exports during
the training.
When passing Exporter to tf.estimator.train_and_evaluate
is_the_final_export is always False if TrainSpec.max_steps is
None .
|
Returns |
The string path to the exported directory or None if export is skipped.
