TweepError：期待長度，突發價值發現大熊貓jupyter筆記本

Question

這是我的代碼，試圖初始化一個類的實例，我得到一個Tweep錯誤

query = 'vacation' 
max_tweets = 1000 

myStreamListener = MyStreamListener() 
myStream = tweepy.Stream(auth = api.auth, listener = myStreamListener) 
myStream.filter(track=[query]) 

時返回看起來像這樣的錯誤：

TweepError        Traceback (most recent call last) 
<ipython-input-31-227d7853c42e> in <module>() 
     4 myStreamListener = MyStreamListener() 
     5 myStream = tweepy.Stream(auth = api.auth, listener = myStreamListener) 
----> 6 myStream.filter(track=[query])

    267    except (Timeout, ssl.SSLError) as exc: 
    268     # This is still necessary, as a SSLError can actually be

    321      break 
    322     else: 
--> 323      raise TweepError('Expecting length, unexpected value found') 
    324 
    325    next_status_obj = buf.read_len(length) 

TweepError: Expecting length, unexpected value found 

我試着對此做一些研究，但是我運氣不好，非常感謝幫助！謝謝！

我正在使用tweepy庫的克隆版本（因爲開發團隊尚未將最新版本推送到pip，而以前的版本不時會引發Nonetype錯誤）。我多次遇到同樣的錯誤。該錯誤是在下面的方法：

def _read_loop(self, resp): 
    charset = resp.headers.get('content-type', default='') 
    enc_search = re.search('charset=(?P<enc>\S*)', charset) 
    if enc_search is not None: 
     encoding = enc_search.group('enc') 
    else: 
     encoding = 'utf-8' 

    buf = ReadBuffer(resp.raw, self.chunk_size, encoding=encoding) 

    while self.running and not resp.raw.closed: 
     length = 0 
     while not resp.raw.closed: 
      line = buf.read_line() 
      if not line: 
       self.listener.keep_alive() # keep-alive new lines are expected 
      elif line.strip().isdigit(): 
       length = int(line) 
       break 
      else: 
       raise TweepError('Expecting length, unexpected value found') 

     next_status_obj = buf.read_len(length) 
     if self.running and next_status_obj: 


self._data(next_status_obj) 

我已經取代

raise TweepError('Expecting length, unexpected value found')

與

self.listener.keep_alive()

到目前爲止它是工作確定，但最終tweepy開發團隊需要解決這個問題。
