TweepError: Expecting length, unexpected value found pandas jupyter notebook

问题

This is my code, trying to initialize an instance of a class and I am getting a Tweep Error

query = 'vacation'
max_tweets = 1000

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

the error that is returned looks like this:

TweepError                                Traceback (most recent call last)
<ipython-input-31-227d7853c42e> in <module>()

TweepError: Expecting length, unexpected value found

I tried to do some research on this, but I ran out of luck, and help is very much appreciated! thank you!

I am working with the cloned version of tweepy library (as the dev team have not pushed the latest release to pip and the previous version throws a Nonetype error now and then). I ran into the same error a number of times. The error is in the following method:

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)

I have replaced

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

with

self.listener.keep_alive()

And so far it is working ok but ultimately the tweepy dev team needs to address this.
