我是 AWS 的新手，并尝试通过参考他们的demo来构建模型（从 Web 控制台） 。但是，当我尝试创建模型时，它给了我以下错误。

无法访问 https://s3.console.aws.amazon.com/s3/buckets/bucket_name model_name/models/处-v0.1.hdf5.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”对于服务主体“sagemaker.amazonaws.com”。还要确保该角色具有“s3:GetObject”权限并且该对象位于eu-west-1中。

我检查了 IAM 角色，它附加了策略AmazonSageMakerFullAccess。AmazonS3FullAccess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"
    }
  ]
}

我正确指定了 ECR 和 S3 路径，但我不知道发生了什么。有人可以帮我解决这个问题吗？

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 执行策略缺少存储桶级别的权限。尝试添加"arn:aws:s3:::<bucket_name>"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 执行策略运行了演示，如下所示，它可以工作。这是非常宽松的政策。一旦它工作，您可以根据您的存储桶名称更改它。

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