I don't know how to solve this issue. Maybe it's because I worked behind a proxy? If so, how to make urllib.urlretrieve work behind the proxy?
Add proxy settings to your global environment to see if it fixes the problem.
sudo gedit /etc/environment
Then add these two lines
http_proxy=http://your_proxy.com:443
https_proxy=https://your_proxy.com:443

Somebody got a similar err?
The problem was caused by a serverproblem of spacy itself and is fixed now.

i am trying to connect to TOR through python but it doesnt let me the code is:
def tor_connection():
socks.setdefaultproxy(socks.PROXY_TYPE_SOCKS5, "127.0.0.1", 9050, True)
socket.socket = socks.socksocket
def main():
tor_connection()
print('Connected to tor')
con = httplib.HTTPConnection('myip.dnsomatic.com/')
con.request('GET', '/')
response = con.getresponse()
print(response.read())
main()
even though its giving me the next error message:

i am just a beginner could someone help me out please? i have tried it in another laptop but its the same error message
It's not a problem of socks. You need to specify the hostname without the trailing /:
>>> # with /
>>> httplib.HTTPConnection('myip.dnsomatic.com/').request('GET', '/')

Your code doesn't work because the "host" argument expects just a hostname and not a url.
If you change it to:
driver = vcloud("login", "passwd", host="portal.vcloud")
it should work.
