我是ML的新手，正在尝试下载MNIST数据。我使用的代码是：
from sklearn.datasets import fetch_mldata
mnist = fetch_mldata('MNIST original')
但是，它给出了一个错误：
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
谁能帮我解决这个问题？
