Théano: AttributeError: module 'Théano' n'a pas d'attribut 'GOF'

Question

La solution présentée dans ce fil ne fonctionne pas pour moi:

Import theano gives the AttributeError: module 'theano' has no attribute 'gof'

J'ai essayé conda install theano (pour ordinateur jupyter) et malgré l'installation parfaitement je reçois toujours l'erreur ci-dessus. J'utilise un ordinateur portable Python 3.6, Windows 7, Anaconda/Jupyter avec un GPU Nvidia 1070. Théano est une version .9.0

Le retraçage est la suivante:

AttributeError: module 'theano' has no attribute 'gof' 

MISE À JOUR:

Je désinstallés Théano en utilisant pip3.6 et Conda (j'ai eu deux versions), puis réinstallé avec conda install theano

maintenant que je reçois cette erreur:

--------------------------------------------------------------------------- 
ModuleNotFoundError      Traceback (most recent call last) 
<ipython-input-6-3397704bd624> in <module>() 
----> 1 import theano 

ModuleNotFoundError: No module named 'theano' 

Essayé de redémarrer le portable Jupyter, obtenant ainsi le No module named 'theano'

EDIT: Réinstallé plusieurs fois. J'ai même redémarré mon ordinateur. Vous rencontrez toujours ce problème. Je vois theano dans le dossier site-packages dans le dossier anaconda. Donc ne pas comprendre quel est le problème.

Le problème a été retourné à:

AttributeError: module 'theano' has no attribute 'gof'

Merci.

Answer 1

Pour moi, c'était un problème de version numpy. Une fois que j'ai réinstallé mon numpy à la version 1.13.1, cela a fonctionné.

Note: Assurez-vous de mettre à jour également les autres paquets qui dépendent de numpy tels que Scikit-learn, etc de manière à être compatibles. Le meilleur moyen est de créer un env juste pour un apprentissage en profondeur.

Answer 2

Pour moi, c'était un problème de compilateur qui résultait d'une mauvaise version (inattendue) g++ utilisée pour la compilation.

En plus du paquet m2w64-toolchain (qui comprend un compilateur g++ qui est « fortement recommandé » pour une utilisation avec Théano, voir installation instructions), j'avais une instance Cygwin installé dont g++.exe a été souligné dans PATH de système Windows variable. Au cours de import theano, la version cygwin a été utilisée à la place de la version m2w64-toolchain.
