Ubuntu 16.04 安装CUDA9.0和cuDNN7.4.1（亲测成功）

目录

一、安装CUDA

二、下载cuDNN

三、设置环境变量

四、查看安装是否成功

一、安装CUDA

1.博主这里选择9.0版本,CUDA历代版本下载的网址为：https://developer.nvidia.com/cuda-toolkit-archive

2.如下选择

                                                                                      

3.执行指令：

sudo dpkg -i cuda-repo-ubuntu1604-9-0-local_9.0.176-1_amd64.deb
sudo apt-key add /var/cuda-repo-9-0-local/7fa2af80.pub
sudo apt-get update
sudo apt-get install cuda

---

二、下载cuDNN

1.网址：https://developer.nvidia.com/rdp/cudnn-archive

2.选择7.4.1的cuDNN Library for Linux下载

                                                                                    

3.解压：

sudo tar -zxvf cudnn-9.0-linux-x64-v7.4.1.5.tgz

                                                 

4.复制cuDNN的文件到已经安装好的目录中

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

---

三、设置环境变量

1.编辑环境变量文件.bashrc

sudo gedit ~/.bashrc

2.最下面添加这几句话

export PATH=/usr/local/cuda/bin${PATH:+:${PATH}}
export LD_LIBRARY_PATH=/usr/local/cuda/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
export CUDA_HOME=/usr/local/cuda

---

四、查看安装是否成功

1.重启电脑/注销用户

2.打开终端，输入

nvcc -V

应该显示如下类似字样

nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2017 NVIDIA Corporation
Built on Fri_Sep__1_21:08:03_CDT_2017
Cuda compilation tools, release 9.0, V9.0.176

3.输入

nvidia-smi

应该显示如下类似字样

说明CUDA和cuDNN安装成功~(没有很可能是环境变量设置出了问题）
