Here is some sampe code of how I have been able to successfully create an instanc

Answer 1

Note: Some Boto3 versions accept either Arn or Name but all versions accept Name. I suggest using the role name only.

IamInstanceProfile={
    'Arn': 'string',
    'Name': 'string'
}

If your profile name is ExampleInstanceProfile and the ARN is arn:aws:iam::123456789012:instance-profile/ExampleInstanceProfile

ec2.create_instances(ImageId='ami-1e299d7e',
                     InstanceType='t2.micro',
                     MinCount=1, MaxCount=1,
                     SecurityGroupIds=['Mysecuritygroup'],
                     KeyName='mykeyname',
                     IamInstanceProfile={
                            'Arn': 'arn:aws:iam::123456789012:instanceprofile/ExampleInstanceProfile'
                            'Name': 'ExampleInstanceProfile'
                     })
