code: def _try_twice_tf_glob(pattern):
    
    try:
      return tf.gfile.Glob(pattern)
    except tf.errors.NotFoundError:
      return tf.gfile.Glob(pattern)
docs: Glob twice, first time possibly catching `NotFoundError`.
  
    tf.gfile.Glob may crash with
  
    ```
    tensorflow.python.framework.errors_impl.NotFoundError:
    xy/model.ckpt-1130761_temp_9cb4cb0b0f5f4382b5ea947aadfb7a40;
    No such file or directory
    ```
  
    Standard glob.glob does not have this bug, but does not handle multiple
    filesystems (e.g. `gs://`), so we call tf.gfile.Glob, the first time possibly
    catching the `NotFoundError`.
  
    Args:
      pattern: str, glob pattern.
  
    Returns:
      list<str> matching filepaths.
