lors de l'exécution du code ci-dessous:
ModuleNotFoundError: No module named 'sklearn.externals.six'
Y a-t-il un module que je n'ai pas importé ou installé?
7 Réponses :
Le module sklearn.externals.six a été supprimé dans la version 0.23. si vous souhaitez utiliser ce module, vous devez revenir à la version 0.22 ou inférieure.
Ce sera dans le module pandas 0.22 car après la mise à jour de la version, il a été supprimé ie sklearn.external.six. vous pouvez vérifier la documentation si toujours confus.
J'ai pu exécuter votre code en exécutant simplement ces commandes:
C:\Windows\system32>pip list ... mglearn 0.1.9 ... scikit-learn 0.23.1 ...
Veuillez noter que j'ai cette version de Python sur mon système:

Rétrograder votre version de scikit-learn:
Dans jupyter notebook, essayez !pip install --upgrade scikit-learn==0.20.3
ou dans le terminal, essayez pip install --upgrade scikit-learn==0.20.3
Après cela, le code reconnaîtra le module sklearn.external.six.
Vous pouvez utiliser le package officiel de six. Installez d'abord six en utilisant: pip install six
, puis importez le module. Pas besoin de rétrograder scikit-learn.
J'arrive en retard, mais cela est dû au package mglearn (qui essaie d'en importer six en interne).
Vous devez avoir une ancienne version, car leurs versions publiées sur github n'ont pas ce problème. Peut-être à partir d'un CD fourni avec le livre ...
Pour résoudre le problème, procédez comme suit:
pip install --upgrade mglearn
Vous pouvez utiliser quelque chose comme ci-dessous.
from six import StringIO
Je ne suis pas familier avec ces packages, mais il peut être utile de savoir quelle version de sklearn vous avez installée.
Veuillez mettre à jour votre message pour inclure 1) la trace d'erreur complète (où l'erreur apparaît-elle exactement?) Ypur scikit-learn version (
sklearn.__version__
