tf.saved_model.experimental.Fingerprint

The SavedModel fingerprint.

tf.saved_model.experimental.Fingerprint(
    saved_model_checksum=None,
    graph_def_program_hash=None,
    signature_def_hash=None,
    saved_object_graph_hash=None,
    checkpoint_hash=None,
    version=None
)

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.

saved_model_checksum Value of thesaved_model_checksum. graph_def_program_hash Value of the graph_def_program_hash. signature_def_hash Value of the signature_def_hash. saved_object_graph_hash Value of the saved_object_graph_hash. checkpoint_hash Value of the checkpoint_hash. version Value of the producer field of the VersionDef.

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 thecheckpoint_hash. version An int32 containing the producer field of the VersionDef.

Methods

from_proto

View source

@classmethod
from_proto(
    proto
)

Constructs Fingerprint object from protocol buffer message.

singleprint

View source

singleprint()

Canonical fingerprinting ID for a SavedModel.

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.

__eq__

__eq__(

)

Return self==value.
