Today in learning PCA using mnist datasets encountered a problem, the code is this:
1 import numpy as np 2 from sklearn.datasets import fetch_mldata 3 4 mnist = fetch_mldata("MNIST original")
We encountered an error: [WinError 10060] Since the connected party did not properly respond after a period of time or host connections did not respond, the connection attempt fails.
the reason:
That is the source address is the wall, and then take the ladder to try, the result was not
Search, I reason, because the source address is not used
Solution:
Use local data sets can be downloaded from: https://github.com/amplab/datascience-sp14/raw/master/lab7/mldata/mnist-original.mat
The fast enough, I can use the Baidu cloud link:
Link: https: //pan.baidu.com/s/1NH1VSnX_Bkvr3k-Dku4gAw
extraction code: herq
After downloading using fetch_mldata good data_home parameter specifies the file directory
E.g:
My Jupyter files in F:, in which a new datasets, and specified in the code \ PyCharmWorkSpace under \ ML
mnist = fetch_mldata("MNIST original",data_home='./datasets')
Until then run, or will complain, do not worry
Open the folder datasets found
Such a subdirectory, the downloaded files into it to go inside, running, OK
