CUDA安装和cuDNN安装
第一步,安装cuda,
到
安装完成后再~/.bashrc文件中添加如下环境变量:
export PATH=/usr/local/cuda-11.7/bin${PATH:+:${PATH}}
export LD_LIBRARY_PATH=/usr/local/cuda-11.7/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
验证是否安装成功,输入nvcc -V指令,得到以下输出表示安装成功
nvcc: NVIDIA (R) Cuda compiler driver

第二步,安装cuDNN
到
输入安装指令:sudo dpkg -i cudnn-local-repo-ubuntu2004-8.4.0.27_1.0-1_amd64.deb
显卡驱动安装(或更新)
查看信息(
-
查看显卡型号:
ubuntu-drivers devices
-
验证是否禁用nouveau:
lsmod | grep nouveau
-
若有输出,证明没有禁用,进行:
sudo gedit /etc/modprobe.d/blacklist.conf
在文件末尾添加:
blacklist nouveau
options nouveau modeset=0
-
应用更改:
sudo update-initramfs -u
-
重启系统,然后执行(没有输出则禁用成功):
lsmod | grep nouveau
-
在实际操作过程中作者在输入第五条命令的时候有输出,但将其忽略也能成功安装。重新启动系统后关闭图形界面:
sudo service lightdm stop
-
如果提示unit lightdm.service not loaded,则先安装(界面选择)LightDm:
sudo apt install lightdm
-
跳出下一个界面后选择lightdm,再:
sudo service lightdm stop
-
更改安装包权限:
sudo chmod a+x NVIDIA****.run(根据具体文件名填写)
-
开始安装:
sudo ./NVIDIA****.run -no-opengl-files
-
启动图像界面:
sudo service lightdm start
-
重启:
sudo reboot -
测试是否成功:
nvidia-smi
驱动安装过程的界面中
The distribution-provided pre-install script failed! Are you sure you want to continue?选择 yes 继续。
Would you like to register the kernel module souces with DKMS? This will allow DKMS to automatically build a new module, if you install a different kernel later?选择 No 继续。
Nvidia’s 32-bit compatibility libraries?选择 No 继续。
Would you like to run the nvidia-xconfigutility to automatically update your x configuration so that the NVIDIA x driver will be used when you restart x? Any pre-existing x confile will be backed up.
