How to use datasets.fetch_mldata() in sklearn?

Question

I am trying to run the following code for a brief machine learning algorithm:

import re
import argparse
import csv
from collections import Counter
from sklea         


        

Answer 1

I also had this problem in the past. It is due to the dataset is quite large (about 55.4 mb), I run the "fetch_mldata" but because of the internet connection, it took awhile to download them all. I did not know and interrupt the process.

The dataset is corrupted and that why the error happened.
