cuda

Perform the pre-installation actions.

sudo apt-get install linux-headers-$(uname -r)
Install repository meta-data

sudo dpkg -i cuda-repo-<distro>_<version>_<architecture>.deb
Update the Apt repository cache

sudo apt-get update
Install CUDA

sudo apt-get install cuda

Perform the post-installation actions

export CUDA_HOME=/usr/local/cuda-8.0

export PATH=$CUDA_HOME/bin:$PATH

# export LD_LIBRARY_PATH=$CUDA_HOME/lib64:${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}

source ~/.bashrc

check:

nvcc --version

nvidia-smi

cuDNN

下载cuDNN后解压

tar -xzvf cudnn-9.0-linux-x64-v7.tgz

sudo cp lib* /usr/local/cuda/lib64/

sudo cp cudnn.h /usr/local/cuda/include/

sudo chmod a+r /usr/local/cuda/include/cudnn.h /usr/local/cuda/lib64/libcudnn*

更新软链接

cd /usr/local/cuda/lib64/

sudo rm -rf libcudnn.so libcudnn.so.5

sudo ln -s libcudnn.so.5.1.5 libcudnn.so.5

sudo ln -s libcudnn.so.5 libcudnn.so

若需要更换cudnn版本，则替换原来的libcudnn*，并重新软链接。

更新链接库

sudo ldconfig
