Udacity：无法在 Ud120 项目中下载数据集 "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")

    return opener.retrieve(url, filename, reporthook, data)

    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，请告诉我如何下载。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 的文件后，文件仍在继续下载。所以，我害怕并阻止了它......大声笑XD。 "enron_mail_20150507.tar.gz" 文件有多大？下载后文件放在哪里？在 ud120 项目中 ?

请帮助我。我卡住了。

问题已解决。我通过 starup.py 中的 link 手动下载了它，并且，文件大小为 1.69 G（压缩）和 2.23 G（解压缩）。
