回答1:

stop_db_cluster() and start_db_cluster() are newer APIs (only released as of a couple of weeks ago. Can you please validate that you're on the latest version of boto3?

pip install --upgrade boto3

回答2:

You need boto version 1.11.721 (2020-02-12) or higher to be exact.

Amazon Neptune

This launch enables Neptune start-db-cluster and stop-db-cluster. Stopping and starting Amazon Neptune clusters helps you manage costs for development and test environments. You can temporarily stop all the DB instances in your cluster, instead of setting up and tearing down all the DB instances each time that you use the cluster.

Upgrade your boto version, and confirm that you are on a version newer than this.
