SCIKIT-HORS - Impossible de charger le jeu de données original mnist à l'aide de FETCH_OPENML IN Python

J'essaie de charger le jeu de données original du mnist en Python. Le sklearn.datasets.fetch_openml La fonction ne semble pas fonctionner pour cela.

Voici le code que j'utilise-

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

Je reçois cette erreur-

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)

http_error_default
    raise HTTPError(req.full_url, code, msg, hdrs, fp)
        urllib.error.HTTPError: HTTP Error 400: Bad Request

Comment puis-je réparer cela? Alternativement, y a-t-il une autre façon de charger le jeu de données Mnist dans Python?

J'utilise la version 0.20.2 de scikit-learn.

Je suis relativement nouveau à la programmation en général, alors j'apprécierais que je puisse avoir une réponse simple. Merci!

Essayer

mnist = fetch_openml('mnist_784')

Je l'ai trouvé via https://www.openml.org/ sous https://www.openml.org/d/554

vous pouvez utiliser:

mist = fetch_openml('mnist_784', version=1)
