惠普暗夜精灵4双系统ubuntu18.04+CUDA10.1+cudnn+pytorch+tensorflow+ros
安装ubuntu18.04：
本机器型号安装ubuntu没有什么疑难杂症,跟着网上大佬的教程，下载镜像文件，做启动盘安装即可。
分区方案：
efi 2G
swap 16G
/ 500G
启动引导选择efi的那个分区
有独显的记得进入编辑启动项 在quite splash 后加 =nomodeset
按F10 进入 try ubuntu 然后安装。
换源
sudo gedit /etc/apt/sources.list
把原文档用下列内容替换
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic main restricted universe multiverse
deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse

deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-proposed main restricted universe multiverse
deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-proposed main restricted universe multiverse
禁用nouveau
sudo gedit /etc/modprobe.d/blacklist.conf
在最后一行加入
blacklist nouveau
options nouveau modeset=0
更新，重启
sudo update-initramfs -u
reboot
装N卡驱动
sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt update
ubuntu-drivers devices
查看本机可装显卡驱动，推荐安装最后有recommend的那个。
sudo apt install nvidia-driver-440
如果该命令无法安装，添加源后再次执行
deb http://archive.ubuntu.com/ubuntu/ trusty main universe restricted multiverse
装完检查
df -h
如果几个Loop都是100%
执行
sudo apt autoremove --purge snapd
清除后再次检查。
重启，一般来说能直接进ubuntu就没有问题了
检查驱动
nvidia-smi
装pip
sudo apt update
sudo apt-get install python-pip
sudo apt-get install python3-pip
装完之后检查
pip --version
pip3 --version
pip换源
mkdir ~/.pip
cd ~/.pip && touch pip.conf
sudo gedit pip.conf
复制粘贴下面
[global]
index-url = http://pypi.douban.com/simple
[install]
use-mirrors =true
mirrors =http://pypi.douban.com/simple/
trusted-host =pypi.douban.com
装chrome
百度搜索chrome，官网下载
CUDA+cudnn+装pytorch
一定要先去pytorch官网看，能直接用pip下载的需要CUDA几！！
自己下包实在是太慢了！
gcc g++降级（有的可以不用）
sudo apt-get install gcc-4.8
sudo apt-get install g++-4.8
ls -l gcc*
sudo mv gcc gcc.bak #备份
sudo ln -s gcc-4.8 gcc #重新链接
ls -l g++*
sudo mv g++ g++.bak
sudo ln -s g++-4.8 g++
gcc -v g++ -v #查看版本号
- 装CUDA
官网下载
sudo sh cuda_10.1.130_410.48_linux.run（文件名自己换） --no-opengl-libs
双显卡一定要加–no-opengl-libs 不然会在登陆界面无限循环
10.0以前的版本是加–no-opengl-files
安装完成后 在bashrc文件内加上
export CUDA_HOME=/usr/local/cuda（或者cuda10.1 看自己版本）
export PATH=$PATH:$CUDA_HOME/bin
export LD_LIBRARY_PATH=/usr/local/cuda-10.0/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
测试
测试：
cd /usr/local/cuda/samples/1_Utilities/deviceQuery
sudo make
./deviceQuery
最后result=pass 成功。
安装CUDNN
官网注册下载
tar -zxvf cudnn-10.1-linux-x64-v7.6.5.32（文件名自己改）.tgz
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*
sudo dpkg -i libcudnn7_7.6.5.32-1+cuda10.1_amd64.deb
sudo dpkg -i libcudnn7-dev_7.6.5.32-1+cuda10.1_amd64.deb
sudo dpkg -i libcudnn7-doc_7.6.5.32-1+cuda10.1_amd64.deb
测试：
cp -r /usr/src/cudnn_samples_v7 $HOME
cd $HOME/cudnn_samples_v7/mnistCUDNN
make clean && make
./mnistCUDNN
test passed 成功。
安装tensorflow
装tensorflow
pip3 install tensorflow-gpu==1.13.1
测试：
python3
import tensorflow as tf
hello=tf.constant("Hello,Tensorflow!")
sess=tf.Session()
print(sess.run(hello))
安装ros
设置源
sudo sh -c '. /etc/lsb-release && echo "deb http://mirrors.tuna.tsinghua.edu.cn/ros/ubuntu/ $DISTRIB_CODENAME main" > /etc/apt/sources.list.d/ros-latest.list'
加key
sudo apt-key adv --keyserver 'hkp://keyserver.ubuntu.com:80' --recv-key C1CF6E31E6BADE8868B172B4F42ED6FBAB17C654
更新
sudo apt-get update
安装ros和一些工具包
sudo apt install ros-melodic-desktop-full
sudo apt-get install ros-melodic-rqt
sudo apt-get install ros-melodic-rqt-common-plugins
装完后在bashrc文件添加
source /opt/ros/melodic/setup.bash
