创建SageMaker模型时的ValidationError

Question

我是AWS的新手，并试图通过引用他们的demo来构建模型（来自Web控制台）。但是，当我尝试创建模型时，它会给出以下错误。

无法访问https://s3.console.aws.amazon.com/s3/buckets/bucket_name/models/model_name-v0.1.hdf5.中的模型数据请确保角色“arn：aws：iam :: id：role / service-role / AmazonSageMaker-ExecutionRole-xxx”存在，并且其信任关系策略允许操作“sts：AssumeRole”for服务负责人“sagemaker.amazonaws.com”。还要确保角色具有“s3：GetObject”权限，并且该对象位于eu-west-1中。

我检查了IAM角色，它附有AmazonSageMakerFullAccess和AmazonS3FullAccess政策。此外，还为角色指定了信任关系（如下所示）。

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Principal": {
        "Service": "sagemaker.amazonaws.com"
      },
      "Action": "sts:AssumeRole"
    }
  ]
}

我正确地指定了ECR和S3路径，但我无法弄清楚发生了什么。有人可以帮我解决这个问题吗？

很抱歉，如果我无法提供更多信息，但如果需要，我会提供任何其他信息。

更新：

以下是IAM政策。

我认为sagemaker执行策略在桶级别缺少权限。尝试将"arn:aws:s3:::<bucket_name>"添加到AmazonSageMaker-ExecutionPolicy-xxx

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Action": [
                "s3:ListBucket"
            ],
            "Effect": "Allow",
            "Resource": [
                "arn:aws:s3:::<bucket_name>"
            ]
        },
        {
            "Action": [
                "s3:GetObject",
                "s3:PutObject",
                "s3:DeleteObject"
            ],
            "Effect": "Allow",
            "Resource": [
                "arn:aws:s3:::<bucket_name>",
                "arn:aws:s3:::<bucket_name>/*"
            ]
        }
    ]
}

我使用SageMaker执行策略运行演示，如下所示。这是一项非常宽松的政策。一旦工作，您可以根据您的桶名更改它。

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "s3:GetObject",
                "s3:PutObject",
                "s3:DeleteObject",
                "s3:ListBucket"
            ],
            "Resource": [
                "arn:aws:s3:::*"
            ]
        }
    ]
}
