Question

J'essaie d'utiliser Keras (Sequential) mais j'obtiens l'erreur suivante lorsque j'essaie de l'importer :

AttributeError: 'module' object has no attribute 'computation'

J'utilise Python 2.7, TensorFlow 1.1, Keras 2.0.3 et j'ai effectué une mise à niveau vers Pandas 0.20.1 hier, ce qui, je le soupçonne, est à l'origine du problème, mais le message d'erreur ne dit rien à ce sujet.

Answer 1

La mise à jour de dask vers 0.15.0 résoudra le problème.

mettre à jour cmd : conda update dask

entrée pip show dask affichera le message suivant

Name: dask
Version: 0.15.0

Answer 2

Dask-0.14.3 fonctionne et élimine l'erreur d'importation

Answer 3

Je suis revenu à la version 0.19.2 de Pandas et le problème a été résolu.

Answer 4

La commande complète que j'utilise est

conda install pandas=0.19.2

et la réponse y pour rétrograder les pandas et ça a marché maintenant.

Answer 5

J'avais installé les versions suivantes :

• python 3.5
• tensorflow 1.2.1
• pandas 0.21
• dask 0.15.3

et j'ai obtenu l'erreur suivante :

pd.core.computation.expressions.set_use_numexpr(False)
AttributeError: 'module' object has no attribute 'expressions'

J'ai rétrogradé en pandas 0.19.2 et dask 0.15.0 et le script python a bien fonctionné !
