tensorflow::ops::MergeV2Checkpoints

V2 format specific: merges the metadata files of sharded checkpoints.

Summary

The

result is one logical checkpoint, with one physical metadata file and renamed data files.

Intended for "grouping" multiple checkpoints in a sharded checkpoint setup.

If delete_old_dirs is true, attempts to delete recursively the dirname of each path in the input checkpoint_prefixes. This is useful when those paths are non user-facing temporary locations.

If allow_missing_files is true, merges the checkpoint prefixes as long as at least one file exists. Otherwise, if no files exist, an error will be thrown. The default value for allow_missing_files is false.

Args:

• scope: A Scope object
• checkpoint_prefixes: prefixes of V2 checkpoints to merge.
• destination_prefix: scalar. The desired final prefix. Allowed to be the same as one of the checkpoint_prefixes.

Optional attributes (see Attrs):

• delete_old_dirs: see above.
• allow_missing_files: see above.

Returns:

• the created Operation
