Question

在提取数据或连接到主机时，我无法连接到互联网。我当前的项目涉及在Python 3.6中使用plot.ly（plotly）创建一个Choropleth和网络图。我已成功按照他们的文档离线创建了网络图。

由于没有Choropleth离线方法，因此我使用以下内容读取数据：

    import urllib 
    urllib.request.urlopen('https://raw.githubusercontent.com/plotly/datasets/master/2011_us_ag_exports.csv')

然后我遇到以下错误消息：

    urllib.error.URLError: <urlopen error [WinError 10060] A connection 
    attempt failed because the connected party did not properly respond after 
    a period of time, or established connection failed because connected host 
    has failed to respond>

我正在通过代理在远程服务器上运行。我已经为HTTP_PROXY和HTTPS_PROXY创建了环境变量。此外，如果输入以下命令，我将获得正确的代理服务器

：

   urllib.request.getproxies()

关于连接到主机以获取在线网络图，如果我键入：

   import urllib3
   import certifi
   from urllib3 import ProxyManager, make_headers
   default_headers = urllib3.make_headers(proxy_basic_auth = 
   'username:password')
   http = urllib3.ProxyManager('http://proxy:port/',
                        headers = default_headers)
   r = http.request('GET', 'http://plot.ly')
   import plotly.plotly as py
   import plotly.graph_objs as go
   import plotly
   plotly.tools.set_credentials_file(username='plotlyuser', 
   api_key='plotlyapikey')
   plotly.tools.set_config_file(world_readable = False, sharing = 'private')

   trace0 = go.Scatter(
   x=[1, 2, 3, 4],
   y=[10, 15, 13, 17]
   )
   trace1 = go.Scatter(
   x=[1, 2, 3, 4],
   y=[16, 5, 11, 9]
   )
   data = [trace0, trace1]
   py.plot(data, filename = 'basic-line', auto_open=True)

我得到以下错误代码（除以上最后一行外，所有代码都运行正常）：

  TimeoutError: [WinError 10060] A connection attempt failed because the 
  connected party 
  did not properly respond after a period of time, or established connection 
  failed because connected host has failed to respond

  plotly.exceptions.PlotlyRequestError: No message

很抱歉，这个问题很长，但是一段时间以来，我一直在努力解决这个问题！
