I am using pymysql in Python to connect to database. It was working fine but now I am getting following error :
Traceback (most recent call last) :

I am using following lines to connect to my database (connection string) :
conn = pymysql.Connect(host='hostname', port=3306, user='username', passwd='password', db='mysql')
Since the pymysql maintainer refuses to release the fix, the solution is simply to install an older version of the package:
pip3 install --user 'pymysql<0.9'
I got the same error and looked like _auth.py was unable to find the reference of byte2int. I added the below line to modify _auth.py to make it work.
from util import byte2int,int2byte
Please be aware the util.py is that of pymysql as there will be util.py files in other packages as well.

I tried
conda update conda

But it didn't help.
Any ideas??
Thanks!!
I have the same problem, and I got it work by running the code using sudo like below:
sudo /Users/edamame/workspace/git/chinese_nlp/venv/bin/python3 chinese_segmenter1.py
Hope this works for you as well.
Same problem here.
A lot of discussion of this points to https://github.com/ContinuumIO/anaconda-issues/issues/1984, which suggests updating to the latest Navigator, and running as root (via sudo).
I've tried both and see no change at all (you may be more fortunate).
https://github.com/Lynten/stanford-corenlp/issues/26 references a tweaked version of corenlp.py that claims to avoid the problem, though I haven't gotten it to work either.
This problem seems to be specific to Mac OS X which would not allow Python to check the current port.
Comment this portion of code of corenlp.py file:
if self.port is None:
for port_candidate in range(9000, 65535):
if port_candidate not in [conn.laddr[1] for conn in psutil.net_connections()]:
self.port = port_candidate
break
if self.port in [conn.laddr[1] for conn in psutil.net_connections()]:
raise IOError('Port ' + str(self.port) + ' is already in use.')
Replace by this line:
self.port = 9999
Source: https://github.com/Lynten/stanford-corenlp/issues/26#issuecomment-445507811
Another solution is to run StanfordCoreNLP with a sudo command line.
Trying to connect to ArangoDB using python

did you try to specify a connection URL like that?
conn = Connection(arangoURL="http://localhost:8529", username="root", password="")
That way it should work.

Im assuming you're using tweepy 3.4.0. The issue you've raised is 'open' on github (https://github.com/tweepy/tweepy/issues/615).
Two work-arounds :
1)
In streaming.py:
I changed line 161 to
self._buffer += self._stream.read(read_len).decode('UTF-8', 'ignore')
and line 171 to
self._buffer += self._stream.read(self._chunk_size).decode('UTF-8', 'ignore')
and then reinstalled via python3 setup.py install on my local copy of tweepy.
2)
remove the tweepy 3.4.0 module, and install 3.3.0 using command: pip install -I tweepy==3.3.0
Hope that helps,
-A
You can't do twitterStream.filter(track="car".strip()). Why are you adding the strip() it's serving no purpose in there.
track must be a str type before you invoke a connection to Twitter's Streaming API and tweepy is preventing that connection because you're trying to add strip()
If for some reason you need it, you can do track_word='car'.strip() then track=track_word, that's even unnecessary because:
>>> print('car'.strip())
car
Also, the error you're getting does not match the code you have listed, the code that's in your question should work fine.
