This repository explains how to install NVIDIA graphic driver (GTX 1080 Ti) on Ubuntu 16.04.

• Ubuntu 16.04
• CUDA 8.0
• Driver version 381.22

1. Install CUDA without the driver

After installed Ubuntu, main graphic driver would be default one. To capture NVIDIA graphic driver, CUDA toolkit should be installed.

• Go to here and download CUDA. Make sure to check correct architecture and distribution types. I choosed runfile(local).

• Add following path location into system file (64-bit machine).

export PATH="/usr/local/cuda/bin:$PATH"

export LD_LIBRARY_PATH="/usr/local/cuda/lib64:$LD_LIBRARY_PATH"

• After installed, reboot system.

2. Install driver with apt-get

Compatible driver version for GTX 1080 Ti is 381 series. Previous trial was directly installing driver using sudo apt-get. However with this method, OS cannot properly capture driver for unknown reason. Therefore I downloaded the latest version of driver runfile from NVIDIA homepage.

• Go to here and selected the appropriate graphic driver version. Make sure the version is same or upper than 381 series.

• Stop the X server and install driver.

• After reboot, the NVIDIA graphic driver would be correctly captured.

3. Verify installation

• nvidia-smi and nvcc -V would be verify installed driver version.

• Go to NVIDIA_CUDA-8.0_Samples/1_Utilities/deviceQuery and make files. After running file, when the driver information is shown property, graphic driver is properly installed!

1. Install OpenCV dependencies

sudo apt-get update sudo apt-get upgrade

sudo apt-get install build-essential cmake pkg-config

sudo apt-get install libjpeg8-dev libtiff5-dev libjasper-dev libpng12-dev

sudo apt-get install libavcodec-dev libavformat-dev libswscale-dev libv4l-dev sudo apt-get install libxvidcore-dev libx264-dev

sudo apt-get install libgtk-3-dev

sudo apt-get install libatlas-base-dev gfortran

2. Download the OpenCV source

cd ~ wget -O opencv.zip https://github.com/Itseez/opencv/archive/3.3.0.zip unzip opencv.zip

wget -O opencv_contrib.zip https://github.com/Itseez/opencv_contrib/archive/3.3.0.zip unzip opencv_contrib.zip

3. Configuring and compiling OpenCV

source activate cv cd ~/opencv/ mkdir build cd build

cmake -D CMAKE_BUILD_TYPE=RELEASE \ -D CMAKE_INSTALL_PREFIX=/usr/local \ -D WITH_CUDA=ON \ -D ENABLE_FAST_MATH=1 \ -D CUDA_FAST_MATH=1 \ -D WITH_CUBLAS=1 \ -D INSTALL_PYTHON_EXAMPLES=ON \ -D INSTALL_C_EXAMPLES=OFF \ -D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib-3.3.0/modules \ -D PYTHON_EXECUTABLE=~/anaconda3/envs/cv/bin/python \ -D WITH_GTK=ON \ -D BUILD_EXAMPLES=ON ..

make -j4

make install

sudo ldconfig

4. Finish OpenCV install

The file cv2.cpython-35m-x86-_64-linux-gnu.so needs to be renamed and sym-linked.

cd ~/usr/local/lib/python3.5/site-packages/ sudo mv cv2.cpython-35m-x86-_64-linux-gnu.so cv2.so

cd ~/anaconda3/envs/cv/lib/python3.5/site-packages/ ln -s /usr/local/lib/python3.5/site-packages/cv2.so cv2.so

At this stage, try import cv2 via python. If error message does not shown, then you have completely installed opencv. In my case, libstdc++.so.6: version GLIBCXX_3.4.21 not found message was shown. conda install libgcc can resolve this error.
