"Le synonyme de type est obsolète ; dans une future version de numpy, il sera compris comme (type, (1,)) / '(1,)type'." problème dans TensorFlow

Question

J'ai installé TensorFlow 1.10.1, mais lorsque j'ai essayé d'importer TensorFlow, il m'a dit que j'avais besoin de TensorFlow version 1.10.0. Ainsi, je l'ai installé et maintenant je reçois les avertissements suivants :

Answer 1

Si vous utilisez TF 2.0, une solution rapide serait de rétrograder votre numpy à 1.16.4. (J'ai utilisé 1.17 et j'ai reçu les mêmes messages d'avertissement).

 1. pip uninstall numpy 
2. pip install numpy==1.16.4

Voir ici (merci à ymodak)

Answer 2

C'est juste un avertissement, pas une erreur. Cela se produit parce que votre version actuelle de la bibliothèque numpy n'est pas compatible avec la version tensorflow. Vous devez rétrograder la version numpy.

tensorflow 1.10.0 a l'exigence numpy<=1.14.5,>=1.13.3 , mais vous devez avoir une version supérieure installée (ce message d'avertissement apparaît avec la dernière version numpy 1.17.0).

Answer 3

Ou, on pourrait simplement faire taire l'avertissement :

 import warnings
warnings.simplefilter(action='ignore', category=FutureWarning)
import tensorflow as tf

Cette approche a été suggérée ici : Comment supprimer l'avertissement Pandas Future ?

Answer 4

pip install "numpy<1.17"

Pour revenir à Numpy version 1.16.4
