Question

这是我的代码。为什么它不起作用

from sklearn.datasets import fetch_mldata
mnist = fetch_mldata('MNIST original', data_home='./data')

当我在cmd中运行它时，我得到了

Traceback (most recent call last):
  File "mnistTest.py", line 7, in <module>
    mnist = fetch_mldata('MNIST original', data_home='./data')
  File "C:\Python27\lib\site-packages\sklearn\datasets\mldata.py", line 142, in
fetch_mldata
    mldata_url = urlopen(urlname)
  File "C:\Python27\lib\urllib2.py", line 154, in urlopen
    return opener.open(url, data, timeout)
  File "C:\Python27\lib\urllib2.py", line 429, in open
    response = self._open(req, data)
  File "C:\Python27\lib\urllib2.py", line 447, in _open
    '_open', req)
  File "C:\Python27\lib\urllib2.py", line 407, in _call_chain
    result = func(*args)
  File "C:\Python27\lib\urllib2.py", line 1228, in http_open
    return self.do_open(httplib.HTTPConnection, req)
  File "C:\Python27\lib\urllib2.py", line 1198, in do_open
    raise URLError(err)
urllib2.URLError: <urlopen error [Errno 10060] A connection attempt failed becau
se the connected party did not properly respond after a period of time, or estab
lished connection failed because connected host has failed to respond>

为什么它不起作用以及我如何使它工作？

Answer 1

fetch_mldata函数从mldata.org获取数据，这似乎已经失效。

为什么我不能在python中使用scikit学习获取mnist数据集
