ValidationError when creating a SageMaker Model - amazon-web-services

Question

I'm new to AWS and trying to build a model (from the web console) by referring to their demo. However, when I try to create the model, it gives me the below error.
Could not access model data at
https://s3.console.aws.amazon.com/s3/buckets/bucket_name/models/model_name-v0.1.hdf5.
Please ensure that the role
"arn:aws:iam::id:role/service-role/AmazonSageMaker-ExecutionRole-xxx"
exists and that its trust relationship policy allows the action
"sts:AssumeRole" for the service principal "sagemaker.amazonaws.com".
Also ensure that the role has "s3:GetObject" permissions and that the
object is located in eu-west-1.
I checked the IAM Role and it has AmazonSageMakerFullAccess and AmazonS3FullAccess policies attached. And also, the trust relationship is also specified for the role (as below).
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Principal": {
"Service": "sagemaker.amazonaws.com"
},
"Action": "sts:AssumeRole"
}
]
}
I'm specifying the ECR and the S3 path correctly, but I can't figure out what is happening. Can someone help me to fix this?
Sorry if I couldn't provide more info, but I will give any other information if required.
UPDATE:
Below are the IAM policies.

Answer 1

I think the sagemaker execution policy is missing permission at bucket level. Try adding "arn:aws:s3:::<bucket_name>" to the 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>/*"
]
}
]
}
I ran the demo with SageMaker execution policy as below and it works. This is much permissive policy. You can change it as per your bucket name once it works.
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": [
"s3:GetObject",
"s3:PutObject",
"s3:DeleteObject",
"s3:ListBucket"
],
"Resource": [
"arn:aws:s3:::*"
]
}
]
}

Try to check the bucket and the data are persisted in eu-west-1
