Python 3.x python tor stem HTTP错误503

我目前正试图通过python获得一个新的ip

proxy_support = urllib.request.ProxyHandler({"http" : "127.0.0.1:8118"})

        newI()

我有我的vidalia和privoxy。我已正确设置设置： Web代理（HTTP）：127.0.0.1:8118，HTTPS也是如此 在privoxy配置文件中，我有以下行：

forward-socks5   /               127.0.0.1:9050 .

虽然当我运行代码时，它仍然停留在案例1中，我无法获得ip。这是我的vidalia的日志：

2. settings > Advanced > 127.0.0.1 : 9051
