AWS S3 Bucket Policy to allow read/write access from aws machine learning

Question

Is it possible to create an S3 bucket policy that allows read and write access from aws machine learning ? I tried below bucket policy, but not work.

bucket policy:

{
    "Version": "2008-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Principal": {
                "Service": "machinelearning.amazonaws.com"
            },
            "Action": [
                "s3:GetObject",
                "s3:PutObject"
            ],
            "Resource": "arn:aws:s3:::cxra/*"
        },
        {
            "Effect": "Allow",
            "Principal": {
                "Service": "machinelearning.amazonaws.com"
            },
            "Action": "s3:PutObjectAcl",
            "Resource": "arn:aws:s3:::cxra/*",
            "Condition": {
                "StringEquals": {
                    "s3:x-amz-acl": "bucket-owner-full-control"
                }
            }
        },
        {
            "Effect": "Allow",
            "Principal": {
                "Service": "machinelearning.amazonaws.com"
            },
            "Action": "s3:ListBucket",
            "Resource": "arn:aws:s3:::cxra"
        },
        {
            "Effect": "Allow",
            "Principal": {
                "Service": "machinelearning.amazonaws.com"
            },
            "Action": [
                "s3:GetBucketLocation"
            ],
            "Resource": "arn:aws:s3:::cxra"
        }
    ]
}

Double check your policy against Granting Amazon ML Permissions to Output Predictions to Amazon S3 and Granting Amazon ML Permissions to Read Your Data from Amazon S3

As they are documented as two separate policies, I suggest you follow that, rather than joining the two policies in one single document. It will be easier to troubleshoot.
