Error importing tensorflow. Unless you are using bazel, 
you should not try to import tensorflow from its source directory; 
please exit the tensorflow source tree, and relaunch your python interpreter 
from there. 

Answer 1

Je ne pense pas que ce soit un problème avec les images. Je pense que la ligne pertinente est:

Library not loaded: @rpath/libcudart.8.0.dylib 

Vous ne chargez pas les bibliothèques CUDA nécessaires. Avez-vous l'intention d'installer avec le support CUDA/GPU? Si oui, vous devriez jeter un oeil à la section pertinente sur le tensorflow installation page.

Answer 2

Vous ne trouvez pas CUDA sur votre système.

S'il vous plaît jeter un oeil à ma réponse ici.
