Import: undefined Symbol: cudnnConvolutionBiasActivationForward

Question

begegnete ich den folgenden Fehler beim Versuch, ein TensorFlow Programm auszuführen:

$ python3

Systeminfo: Ubuntu 16.04 Cuda 8.0 cudnn 5.1 tensorflow-gpu Version

Answer 1

As mentioned here eine Kraft wieder installieren sollte den Trick oder die Herabstufung auf eine niedrigere tensorflow Version tun wird auch funktionieren:

pip3 install tensorflow-gpu --upgrade --force-reinstall 

Eine mögliche Ursache für dieses Problem ist, wenn Sie sowohl Tensorflow-CPU als auch Tensorflow-GPU installiert haben.
