Jupyter Notebook：[WinError 10060] 连接尝试失败，因为连接方在一段时间后没有正确响应

Question

I'm trying to run the following code in jupyter Notebooks

from sklearn.datasets import fetch_mldata
mnist = fetch_mldata('MNIST original')

and getting the following error

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

I'm on a windows 10 machine with Anaconda {version: '4.7.12'}, python {version: '3.7.4'}

Is this related to HTTP Proxy? I'm not sure how to configure it with jupyter notebooks. Please help.

Answer 1

Looks like you're not alone. I'm getting a time out error too. I'm not using a proxy or jupyter so it probably is just that the source is down.

>>> from sklearn.datasets import fetch_mldata
>>> mnist = fetch_mldata('MNIST original')
...
TimeoutError: [Errno 60] Operation timed out

Based on the discussion at https://github.com/scikit-learn/scikit-learn/issues/8588 , it looks like this is a wider spread problem.

The following source works for me though.

>>> from sklearn.datasets import fetch_openml
>>> mnist = fetch_openml('mnist_784')
