Kein Modul mit dem Namen "_pywrap_tensorflow_internal"

Beim Versuch, die Installation von tensorflow-gpu zu überprüfen, erhalte ich beim Ausführen von "import tensorflow as tf" einen ImportError. Ich verwende eine Quadro K620 unter Windows 7. Tensorflow wurde mit pip installiert. 

Folgendes ist die Stapelablaufverfolgung:

Ich habe mir mehrere andere Stapelüberlaufpfosten angesehen, bei denen der Pfad korrigiert wurde, aber ich konnte dieses Problem nicht lösen.
