ubuntu16.04环境下

1.cudnn5.1的安装

sudo cp /home/ujx/3rdParty/cuda_5/include/cudnn.h /usr/local/cuda/include/
sudo cp /home/ujx/3rdParty/cuda_5/lib64/lib* /usr/local/cuda/lib64/
cd /usr/local/cuda/lib64/ 


sudo rm -rf libcudnn.so libcudnn.so.5
sudo ln -s libcudnn.so.5.1.10 libcudnn.so.5
sudo ln -s libcudnn.so.5 libcudnn.so

2.cudnn6.0的安装

sudo cp /home/ujx/3rdParty/cuda_6/include/cudnn.h /usr/local/cuda/include/
sudo cp /home/ujx/3rdParty/cuda_6/lib64/lib* /usr/local/cuda/lib64/
cd /usr/local/cuda/lib64/ 


sudo rm -rf libcudnn.so libcudnn.so.6
sudo ln -s libcudnn.so.6.0.21 libcudnn.so.6
sudo ln -s libcudnn.so.6 libcudnn.so

3. 移除cudnn

sudo rm -rf /usr/local/cuda/include/cudnn.h
sudo rm -rf /usr/local/cuda/lib64/libcudnn*

4. nvidia驱动安装-ubuntu
   ppa源安装驱动

sudo add-apt-repository ppa:graphics-drivers/ppa  
sudo apt-get update  

然后在系统的additional drivers 选择版本。

5. cuda下载

6. cuda 和 nvidia驱动卸载

# Use the following command to uninstall a Toolkit runfile installation:
$ sudo /usr/local/cuda-X.Y/bin/uninstall_cuda_X.Y.pl
# Use the following command to uninstall a Driver runfile installation:
$ sudo /usr/bin/nvidia-uninstall
