安装cuda和cudnn

 

原来机器上有安装一个cuda 10.0,想要再安装一个cuda 10.1

安装CUDA

1.首先下载.run文件

https://developer.nvidia.com/cuda-10.1-download-archive-base?target_os=Linux&target_arch=x86_64&target_distro=CentOS&target_version=7&target_type=runfilelocal

 

安装cuda和cudnn

 

 

2.首先给.run文件执行权限

chmod a+x cuda_10.1.105_418.39_linux.run

3.运行

sh cuda_10.1.105_418.39_linux.run

1)敲accept

安装cuda和cudnn

 2)去掉驱动下载,因为这里我的驱动已经下好

安装cuda和cudnn

 3)yes

安装cuda和cudnn

 4) 

 

 安装cuda和cudnn

 需要进行下设置

1》

(base) [root@10_1_5_103 var]# bash -c "echo /usr/local/cuda-10.1/lib64/ > /etc/ld.so.conf.d/cuda.conf"
(base) [root@10_1_5_103 var]# ldconfig

 2》添加到~/.bashrc:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda-10.1/lib64 
export PATH=$PATH:/usr/local/cuda-10.1/bin
export CUDA_HOME=/usr/local/cuda-10.1 

 然后运行source ~/.bashrc

3》同时更改:

# vim /etc/profile
# source /etc/profile

加入:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda-10.1/lib64
export PATH=$PATH:/usr/local/cuda-10.1/bin
export CUDA_HOME=/usr/local/cuda-10.1 

4》查看cuda版本:

(base) [root@... var]# nvcc -V
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2019 NVIDIA Corporation
Built on Fri_Feb__8_19:08:17_PST_2019
Cuda compilation tools, release 10.1, V10.1.105

 

4.测试例子效果:

cd .../NVIDIA_CUDA-10.1_Samples/1_Utilities/bandwidthTest
make
./bandwidthTest

返回:

安装cuda和cudnn

 

5.查看torch调用的cuda:

>>> import torch
>>> print(torch.version.cuda)
10.0

但是这不说明其使用的真的是这个,查看:

>>> import torch.utils.cpp_extension
>>> torch.utils.cpp_extension.CUDA_HOME
'/usr/local/cuda-10.1'

可见改了

 

安装cuDNN

打开链接https://developer.nvidia.com/cudnn,需要先注册和填写信息,之后选择对应版本的安装包

安装cuda和cudnn

 

1.版本8

1)解压:

tar -zxvf cudnn-10.1-linux-x64-v8.0.5.39.tgz

会在当前文件下生成一个cuda文件夹

2)操作:

sudo cp cuda/include/cudnn.h /usr/local/cuda-10.1/include/ 
sudo cp cuda/include/cudnn_version.h /usr/local/cuda-10.1/include/ 
sudo cp cuda/lib64/libcudnn* /usr/local/cuda-10.1/lib64/ 
sudo chmod a+r /usr/local/cuda-10.1/include/cudnn.h 
sudo chmod a+r /usr/local/cuda-10.1/lib64/libcudnn*

3)查看版本:

cat /usr/local/cuda-10.1/include/cudnn_version.h | grep CUDNN_MAJOR -A 2

返回:

#define CUDNN_MAJOR 8
#define CUDNN_MINOR 0
#define CUDNN_PATCHLEVEL 5
--
#define CUDNN_VERSION (CUDNN_MAJOR * 1000 + CUDNN_MINOR * 100 + CUDNN_PATCHLEVEL)

#endif /* CUDNN_VERSION_H */

 

2.版本7

如果是cudnn7版本的:

1)解压:

tar -zxvf cudnn-10.1-linux-x64-v7.6.5.32.tgz

会在当前文件下生成一个cuda文件夹

2)操作:

sudo cp cuda/include/cudnn.h /usr/local/cuda-10.1/include/ 
sudo cp cuda/lib64/libcudnn* /usr/local/cuda-10.1/lib64/ 
sudo chmod a+r /usr/local/cuda-10.1/include/cudnn.h 
sudo chmod a+r /usr/local/cuda-10.1/lib64/libcudnn*

3)查看版本:

cat /usr/local/cuda-10.1/include/cudnn.h | grep CUDNN_MAJOR -A 2

返回:

#define CUDNN_MAJOR 7
#define CUDNN_MINOR 6
#define CUDNN_PATCHLEVEL 5
--
#define CUDNN_VERSION (CUDNN_MAJOR * 1000 + CUDNN_MINOR * 100 + CUDNN_PATCHLEVEL)

#include "driver_types.h"
