[`tf.compat.v1.raw_ops.MergeV2Checkpoints`](https://www.tensorflow.org/api_docs/python/tf/raw_ops/MergeV2Checkpoints)

<br />

    tf.raw_ops.MergeV2Checkpoints(
        checkpoint_prefixes,
        destination_prefix,
        delete_old_dirs=True,
        allow_missing_files=False,
        name=None
    )

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.
