Defined in tensorflow/contrib/training/python/training/evaluation.py.

Waits until a new checkpoint file is found.

Args:

• checkpoint_dir: The directory in which checkpoints are saved.
• last_checkpoint: The last checkpoint path used or None if we're expecting a checkpoint for the first time.
• seconds_to_sleep: The number of seconds to sleep for before looking for a new checkpoint.
• timeout: The maximum amount of time to wait. If left as None, then the process will wait indefinitely.

Returns:

a new checkpoint path, or None if the timeout was reached.
