HOW TO : Install Cuda and Cudnn with GTX 1080.

1.INSTALL DRIVER FOR GTX 1080

The first time that you install the card in the computer and connect the HDMI to it the resolution will be the worst, so u need to install the drivers

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
sudo apt install nvidia-367
sudo reboot

Go settigns and now , you can configure your resolution.

2.INSTALL CUDA.

Go to his link CUDA LINK . in my case i download the version for UBUNTU 16.04 – runfile(local).

Go to the console and run :

sudo sh cuda_8.0.61_375.26_linux.run

Follow the instructions.

Remember that you already install the driver for nvidia so , u should write no.

3.INSTALL CUDNN

CUDNN is the library for neural network of nvidia, with this library you can train your own neural network with framework like caffe , tensor flow or darknet.

$ cd folder/extracted/contents
$ sudo cp -P include/cudnn.h /usr/include
$ sudo cp -P lib64/libcudnn* /usr/lib/x86_64-linux-gnu/
$ sudo chmod a+r /usr/lib/x86_64-linux-gnu/libcudnn*

Path environment variables

cd
sudo nano ./bashrc

paste the following lines in the end of .bashrc

export PATH=$PATH:/usr/local/cuda/bin
export LD_LIBRAY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda/lib64
export CUDA_HOME=/usr/local/cuda
export LD_LIBRARY_PATH=/usr/local/cuda/lib
if [ -z $LD_LIBRARY_PATH ]; then
  LD_LIBRARY_PATH=/usr/local/cuda/lib64:/usr/local/cuda/lib
else
  LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda/lib64:/usr/local/cuda/lib
fi
export LD_LIBRARY_PATH
export LD_LIBRARY_PATH=/usr/local/cuda8.0/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}

save and close the terminal.

Now check the nvcc

nvcc --version
