Keras getting an error when using TensorFlow-gpu

Question

I'm trying to run Keras with TensorFlow as a backend, but I want to run it on my GPU. I installed TensorFlow-gpu, CUDA 8.0, and cuDNN, but Keras gets the following error:

I only have the gpu version of tensorflow installed, and I've double-checked my gpu driver is up-to-date. I searched around for a few hours, but couldn't find any solutions to an issue like this.

Answer 1

Just to answer this, tensorflow currently on version 1.3 doesn't support cuDNN 7, but they will in 1.4.

If you ever have this problem again, make sure to check the official documentation on which exact version of Cuda and CuDNN to use with your version of tensorflow.
