Each attribute of this class is named after a field name in the FingerprintDef proto and contains the value of the respective field in the protobuf. Attributes: saved_model_checksum: A uint64 containing the `saved_model_checksum`. graph_def_program_hash: A uint64 containing `graph_def_program_hash`. signature_def_hash: A uint64 containing the `signature_def_hash`. saved_object_graph_hash: A uint64 containing the `saved_object_graph_hash`. checkpoint_hash: A uint64 containing the`checkpoint_hash`. version: An int32 containing the producer field of the VersionDef.

Uniquely identifies a SavedModel based on the regularized fingerprint attributes. (saved_model_checksum is sensitive to immaterial changes and thus non-deterministic.) Returns: The string concatenation of `graph_def_program_hash`, `signature_def_hash`, `saved_object_graph_hash`, and `checkpoint_hash` fingerprint attributes (separated by '/'). Raises: ValueError: If the fingerprint fields cannot be used to construct the singleprint. z[Encounted invalid fingerprint values when constructing singleprint.graph_def_program_hash: zsignature_def_hash: zsaved_object_graph_hash: zcheckpoint_hash: N) fingerprinting_pywrap Singleprintr r r r TypeErrorFingerprintExceptionr)rrs r singleprintzFingerprint.singleprintxs  " . .t/J/J/3/F/F/3/K/K/3/C/CEE ,AA B  %%)%@%@$A !8!8 9 %d&B&B%C d223 C     s?AB"ABB")NNNNNN)__name__ __module__ __qualname____doc__intr classmethodrrr rboolr#strr(r+r-r.r1rrr r s "#'$( $%)!"  #   4_;; " # $ s((0<<rr z)saved_model.experimental.read_fingerprint export_dirrc8 tj|}t jtjj|S#tj$r}td|dd}~wtj$r}t d|dd}~wwxYw)a9Reads the fingerprint of a SavedModel in `export_dir`. Returns a `tf.saved_model.experimental.Fingerprint` object that contains the values of the SavedModel fingerprint, which is persisted on disk in the `fingerprint.pb` file in the `export_dir`. Read more about fingerprints in the SavedModel guide at https://www.tensorflow.org/guide/saved_model. Args: export_dir: The directory that contains the SavedModel. Returns: A `tf.saved_model.experimental.Fingerprint`.
