tf.compat.v1.train.checkpoint_exists

Checks whether a V1 or V2 checkpoint exists with the specified prefix. (deprecated)

tf.compat.v1.train.checkpoint_exists(
    checkpoint_prefix
)

This is the recommended way to check if a checkpoint exists, since it takes into account the naming difference between V1 and V2 formats.

Args
checkpoint_prefix	the prefix of a V1 or V2 checkpoint, with V2 taking priority. Typically the result of Saver.save() or that of tf.train.latest_checkpoint(), regardless of sharded/non-sharded or V1/V2.

Returns
A bool, true if a checkpoint referred to by checkpoint_prefix exists.
