Sagemaker本地部署：“RuntimeError: Giving up, endpoint: didn't launch correctly”

【以下的问题经过翻译处理】 你好， 我正在尝试在本地启动一个endpoint，从我的开发notebook上进行一些推理（无需等待实际端点的实例化时间或批量训练）。我正在运行以下代码：

# get trained model from s3
trained_S2S = SM.model.Model(
    image = seq2seq，
    model_data =（'s3://XXXXXXXXXXXXX/'
        +'output/seq2seq-2018-07-30-16-55-12-521/output/model.tar.gz'），
    role = role) 
S2S = trained_S2S.deploy(1, instance_type = 'local')   

我得到以下错误（重复了几百行）：

WARNING:urllib3.connectionpool:Retrying (Retry(total=1, connect=None, read=None, redirect=None, status=None)) after connection broken by 'NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7fa5c61eaac8>: Failed to establish a new connection: [Errno 111] Connection refused',)': /ping
