Description:
 def _try_twice_tf_glob(pattern):
 """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. """
