Kann nicht MNIST-Datenbank über Anaconda/jupyter

Hu Jungs,

Ich bin neu in python/anaconda/jupyter/numPy, Pandas, usw.... also bitte entschuldigen Sie mich, wenn es eine wirklich dumme Frage.
Ich versuche zu erhalten MNIST-Datenbank mithilfe von anaconda/jupyter. Doch jedesmal bekomme ich einen HTTP 500-Fehler am Ende. Ist es wirklich ein server-problem (wie 500 würde vorschlagen) oder mache ich etwas falsch?

Eingang in jupyter:

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

Ergebnis:

    ---------------------------------------------------------------------------
    HTTPError                                 Traceback (most recent call last)

    HTTPError: HTTP Error 500: INTERNAL SERVER ERROR
  • Die Fehlermeldung gibt einen HTTP-Fehler 500 bedeutet interner Serverfehler. So, die meisten wahrscheinlich, es ist ein Fehler auf dem server. Ich würde versuchen Sie es später erneut. Wenn Sie Auschecken der ulr mldata.org Sie werden sehen, es ist derzeit nicht verfügbar.
