The current AWS identity is not a role for sagemaker?

问题

I am getting error when i call get_execution_role() from sagemaker in python. I have attached the error for the same.

I have added the SagemakerFullAccess Policy to role and user both.

回答1:

get_execution_role() is a function helper used in the Amazon SageMaker Examples GitHub repository.

These examples were made to be executed from the fully managed Jupyter notebooks that Amazon SageMaker provides.

From inside these notebooks, get_execution_role() will return the IAM role name that was passed in as part of the notebook creation. That allows the notebook examples to be executed without code changes.

From outside these notebooks, get_execution_role() will return an exception because it does not know what is the role name that SageMaker requires.

To solve this issue, pass the IAM role name instead of using get_execution_role().

Instead of:

role = get_execution_role()

kmeans = KMeans(role=role,
                train_instance_count=2,
                train_instance_type='ml.c4.8xlarge',
                output_path=output_location,
                k=10,
                data_location=data_location)

you need to do:

role = 'role_name_with_sagemaker_permissions'

kmeans = KMeans(role=role,
                train_instance_count=2,
                train_instance_type='ml.c4.8xlarge',
                output_path=output_location,
                k=10,
                data_location=data_location)

I struggled with this for a while and there are a few different pieces but I believe these are the steps to solve (according to this doc)

You must add a role to your aws config file. Go to terminal and enter:

~/.aws/config

Add your own profile

[profile marketingadmin]
role_arn = arn:aws:iam::123456789012:role/marketingadmin
source_profile = default

Then Edit Trust Relationships in the AWS Dashboard:

add this and update:

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Principal": {
        "Service": "sagemaker.amazonaws.com",
        "AWS": "arn:aws:iam::XXXXXXX:user/YOURUSERNAME"
      },
      "Action": "sts:AssumeRole"
    }
  ]
}

Lastly, I clicked the link that says

Give this link to users who can switch roles in the console

After adding my credentials - it worked.

thanks for trying out SageMaker!

The exception you are seeing already suggests the reason. The credentials you are using are not a role credentials but most likely a user. The format of 'user' credentials will look like:

'arn:aws:iam::accid:user/name' as opposed to a role: 'arn:aws:iam::accid:role/name'

Hope this helps!
