在twitter流API中避免速率限制（错误：420）

Question

我正在尝试使用python中的tweepy库从twitter-streaming-api中获取流数据。但是，即使经过大量试验，我也无法获得任何data或按照on_data方法进行打印。它给出了420错误消息。我怎么能避免呢？

import io
import json
import time
import tweepy


access_token = 'XXXXXX'
access_token_secret = 'XXXXXX'
consumer_key = 'XXXXXX'
consumer_secret = 'XXXXXX'

class MyListener(tweepy.StreamListener):

    def on_status(self, status):
        print(status.text)

    def on_data(self, tweetdata):
        data = json.loads(tweetdata)           
        print(data)

    def on_error(self, status):
        print(status)

auth = tweepy.OAuthHandler(consumer_secret=consumer_secret,consumer_key=consumer_key)
auth.set_access_token(access_token,access_token_secret)
api = tweepy.API(auth)

myListener = MyListener()
myStream = tweepy.Stream(auth = api.auth, listener=myListener)
myStream.filter(languages='en',track=['@NBA'],async=True)
myStream.disconnect()
