Cuda installation

Installing Nvidia Driver

Method 1 :

• Download directly from the Nvidia website [Nvi] according to the GPU processor.http://www.nvidia.de/Download/index.aspx

• Then go to boot menu and disable the secured boot then in terminal

    $ chmod +x Nvidia driver
    $ sudo ./nvidia driver
  

Method 2 : In Terminal window(Recommended)

$ sudo apt-get purge nvidia*
$ sudo add-apt-repository ppa:graphics-drivers/ppa
$ sudo apt-get update
$ sudo apt-get install nvidia-driver-440

After this reboot the pc then open terminal and type nvidia-smi
a display in the terminal with driver version ill be displayed

Manditory step before installing cuda

Create a file at
sudo nano /etc/modprobe.d/blacklist-nouveau.conf   
copy this and paste in it:
blacklist nouveau options nouveau modeset=0
	$ sudo update-initramfs -u
	$ sudo reboot

Download link for cuda

Install nvidia CUDA

	$ sudo dpkg -i cuda-repo-<distro>_<version>_<architecture>.deb
	$ sudo apt-key add /var/cuda-repo-<version>/7fa2af80.pub
	$ sudo apt-get update
	$ sudo apt-get install cuda

Manditory task to add in bashrc file

1.Type nano ~/.bashrc in terminal
2.paste the required path  the below
	#cuda
	 export PATH=/usr/local/cuda-10.2/bin:/usr/local/cuda-10.1/NsightCompute-2019.1${PATH:+:${PATH}}
	 export LD_LIBRARY_PATH=/usr/local/cuda-10.1/lib\${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
3.After pasting type source ~/.bashrc

POST INSTALLATION:

Copy the samples from cuda(usr/local/cuda)
paste in home directory
go to device query 
make clean
make
./devicequery
result:Pass
After this type nvcc --version  in terminal you will get the cuda version if this displayes success

Installing CUDNN

The order of versions has to be installed:

	$ sudo dpkg -i libcudnn7 7.6.2.11-1+cuda9.0 amd64.deb
	$ sudo dpkg -i libcudnn7-dev 7.6.2.11-1+cuda9.0 amd64.deb
	$ sudo dpkg -i libcudnn7-doc 7.6.2.11-1+cuda9.0 amd64.deb

Post Installation

	$ cp -r /usr/src/cudnn_samples_v7/ $HOME
            $ cd  $HOME/cudnn_samples_v7/mnistCUDNN
	$ make clean && make
	$ ./mnistCUDNN

Install TensorFlow

	$sudo pip install tensorflow(CPU support)
	$sudo pip install tensorflow-gpu(GPU support)
