NameError: name 'memoryview' is not defined

the codes these:

from kafka import KafkaProducer
from kafka import KafkaConsumer
from kafka.errors import KafkaError
import json

class Kafka_producer():

    def __init__(self, kafkahost,kafkaport, kafkatopic):
        self.kafkatopic = kafkatopic
        service_host = kafkahost+":"+kafkaport
        self.producer = KafkaProducer(bootstrap_servers=service_host)

    def sendjsondata(self, params):
        try:
            # parmas_message = json.dumps(params)
            producer = self.producer
            futur = producer.send(self.kafkatopic, params.encode('utf-8'))
            res = futur.get(timeout=60)
            producer.flush()
            producer.close()
        except KafkaError as e:
            print e

if __name__ == '__main__':
    # test = {
    #     "test":"testtets"
    # }
    # Kafka_producer("http://10.25.245.192","9092","nori-log").sendjsondata(test)
    producer = KafkaProducer(bootstrap_servers='10.25.245.192:9092')
    for _ in range(100):
        producer.send('nori-log', {"test":"test_content"})
