Hi,
I have an Ubuntu 16.04 box with the latest version of Anacoda installed. I’ve created and activated a Python 2.7 environment. I’ve installed Keras v1.1.1. ($ conda install keras==1.1.1
). My GPU is a Nvidia GTX 1080 ti.
I installed CUDA 8.0 because I was previously doing deep learning work with Python 3.6 & Keras 2.0.
This is what I get when I try to import Theano (this also happens when running the Lesson1 notebook):
$ KERAS_BACKEND=theano python -c "from keras import backend"
Using Theano backend.
WARNING (theano.sandbox.cuda): The cuda backend is deprecated and will be removed in the next release (v0.10). Please switch to the gpuarray backend. You can get more information about how to switch at this URL:

warnings.warn(warn)
So no GPU for me. Do I need to downgrade to a previous version of CUDA?
Thanks
My CUDA setup:
