Python sagemaker.tensorflow.serving预测失败，出现502错误
我使用以下代码在上部署了tensorflow saved_模型：Python sagemaker.tensorflow.serving预测失败，出现502错误,python,tensorflow-serving,amazon-sagemaker,Python,Tensorflow Serving,Amazon Sagemaker,我使用以下代码在上部署了tensorflow saved_模型： `model_path = 's3://' + sagemaker_session.default_bucket() + '/model/model.tar.gz' from sagemaker.tensorflow.serving import Model model = Model(model_data=model_path, role=role) predictor = model.deploy(initial_instan
