是否升级EMR集群？

import boto3

client = boto3.client('emr', region_name='ap-guangzhou')

response = client.run_job_flow(
    Name='MyEMRCluster',
    ReleaseLabel='emr-6.3.0',
    Instances={
        'InstanceGroups': [
            {
                'Name': 'Master',
                'InstanceRole': 'MASTER',
                'InstanceType': 'm5.xlarge',
                'InstanceCount': 1,
            },
            {

                'InstanceRole': 'CORE',
                'InstanceType': 'm5.xlarge',
