Udacity：无法在 Ud120-projects 中下载数据集“enron_mail_20150507.tar.gz”

Question

我无法通过“python startup.py”下载“enron_mail_20150507.tar.gz”。我收到以下错误，不知道如何解决。

    downloading the Enron dataset (this may take a while)
    to check on progress, you can cd up one level, then execute <ls -lthr>
    Enron dataset should be last item on the list, along with its current 
    size
    download will complete at about 423 MB
    Traceback (most recent call last):
    File "startup.py", line 36, in
    urllib.urlretrieve(url, filename="../enron_mail_20150507.tar.gz")
    File "C:\Python27\lib\urllib.py", line 98, in urlretrieve
    return opener.retrieve(url, filename, reporthook, data)
    File "C:\Python27\lib\urllib.py", line 245, in retrieve
    fp = self.open(url, data)
    File "C:\Python27\lib\urllib.py", line 213, in open
    return getattr(self, name)(url)
    File "C:\Python27\lib\urllib.py", line 350, in open_http

    self.connect()

    for res in getaddrinfo(host, port, 0, SOCK_STREAM):
    IOError: [Errno socket error] [Errno 11001] getaddrinfo failed

我尝试将“startup.py”中的 url 更改为“http://www.cs.cmu.edu/~enron/enron_mail_20150507.tar.gz”，但它也不起作用。如果有人在WINDOW上使用python下载它，请告诉我如何。我真的很感激。

无论如何，我尝试手动下载它，但即使下载了 1.1 GB 的文件，该文件仍在继续下载。所以，我很害怕并停止了它......哈哈XD。 “enron_mail_20150507.tar.gz”文件有多大？文件下载后放在哪里？在 ud120-projects 中？

请帮助我。我卡住了。

问题解决了。我通过starup.py中的链接手动下载了它， 文件大小为 1.69 G（压缩）和 2.23 G（解压缩）。
