Install CUDA 8.0

sudo dpkg -i cuda-repo-ubuntu1604-8-0-local-ga2_8.0.61-1_amd64.deb

sudo apt-get update
sudo apt-get install cuda

Update

sudo dpkg -i cuda-repo-ubuntu1604-8-0-local-cublas-performance-update_8.0.61-1_amd64.deb

sudo apt-get update
sudo apt-get upgrade

Add libraries to .bashrc file,

echo 'export PATH=/usr/local/cuda/bin:$PATH' >> ~/.bashrc
echo 'export LD_LIBRARY_PATH=/usr/local/cuda/lib64:$LD_LIBRARY_PATH' >> ~/.bashrc
source ~/.bashrc

After sourcing the bashrc file, the CUDA version can be verified using

nvcc -V

Next step is to install cuDNN. cuDNN can be downloaded from NVIDIA’s webpage https://developer.nvidia.com/cudnn.

Extract cuDNN and install.

cd ~/Downloads/
tar xvf cudnn*.tgz
cd cuda
sudo cp */*.h /usr/local/cuda/include/
sudo cp */libcudnn* /usr/local/cuda/lib64/
sudo chmod a+r /usr/local/cuda/lib64/libcudnn*

Once finished those above, install tensorflow in virtulenv and activate it.
