Scikit-learn - Cannot load MNIST Original dataset using fetch_openml in Python

Question

I'm trying to load the MNIST Original dataset in Python. The sklearn.datasets.fetch_openml function doesn't seem to work for this.

Here is the code I'm using-

from sklearn.datasets import fetch_openml
dataset = fetch_openml("MNIST Original") 

I get this error-

File "generateClassifier.py", line 11, in <module>
  dataset = fetch_openml("MNIST Original")
  File "/home/inglorion/.local/lib/python3.5/site- 
packages/sklearn/datasets/openml.py", line 526, in fetch_openml
data_info = _get_data_info_by_name(name, version, data_home)
  File "/home/inglorion/.local/lib/python3.5/site- 
packages/sklearn/datasets/openml.py", line 302, in 
_get_data_info_by_name
    data_home)
  File "/home/inglorion/.local/lib/python3.5/site- 
packages/sklearn/datasets/openml.py", line 169, in

  File "/home/inglorion/.local/lib/python3.5/site-

    return f()

  File "/usr/lib/python3.5/urllib/request.py", line 472, in open
    response = meth(req, response)
  File "/usr/lib/python3.5/urllib/request.py", line 582, in

    'http', request, response, code, msg, hdrs)
  File "/usr/lib/python3.5/urllib/request.py", line 510, in error
    return self._call_chain(*args)
  File "/usr/lib/python3.5/urllib/request.py", line 444, in 
_call_chain
    result = func(*args)
  File "/usr/lib/python3.5/urllib/request.py", line 590, in 
http_error_default
    raise HTTPError(req.full_url, code, msg, hdrs, fp)
        urllib.error.HTTPError: HTTP Error 400: Bad Request

How can I fix this? Alternately, is there any other way to load the MNIST dataset into Python?

I'm using version 0.20.2 of scikit-learn.

I'm relatively new to programming in general, so I would appreciate it if I could get a simple answer. Thanks!

Try

mnist = fetch_openml('mnist_784')

I found it via https://www.openml.org/ under https://www.openml.org/d/554
