Some Easy Steps For GPU Installation

Webtunix Blog

GPU stands for Graphic Processing Unit, it is a special kind of computer processor designed for handling graphics.

GPU Installation Steps:

For Ubuntu 16.04 users, we have to download some drivers.

Step 1: Downloading NVIDIA Driver
To remove unnecessary files and load fresh drivers write following commands.
sudo apt-get purge nvidia-*
sudo apt-get autoremove #[for removing temporary data]
sudo reboot #[It restarts the PC]

Step 2: Installing gcc 4.9 compiler
It will help us to avoid compile errors with Theano.
sudo apt-get install gcc-4.9 g++-4.9
sudo ln -s /usr/bin/gcc-4.9 /usr/bin/gcc -f
sudo ln -s /usr/bin/g++-4.9 /usr/bin/g++ -f

Step 3: Downloading CUDA 8.0 RC
Download runfile(local), when installing cuda 8.0 decline on installing NVIDIA drivers and then reboot.
sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
sudo apt-get install nvidia-367
sudo reboot

After then type command nvidia-smi to check whether NVIDIA drivers are installed or not. If it is properly installed you will get
following text.

Step 4: Export path
1. For exporting path of NVIDIA, check the file of CUDA named bsah.bash rc where you have to copy following lines.
export PATH=/usr/local/cuda-8.0/bin${PATH:+:${PATH}}
export LD_LIBRARY_PATH=/usr/local/cuda-8.0/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
2. Then run $soure ~/.bashrc command and type nvcc -V which which you will be able to check GPU is configured or not.
