1 安装Ubuntu18.04.03 lts
spt@spt-ts:~$ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 18.04.3 LTS Release: 18.04 Codename: bionic spt@spt-ts:~$ df -ah Filesystem Size Used Avail Use% Mounted on udev 3.9G 0 3.9G 0% /dev tmpfs 794M 1.9M 792M 1% /run /dev/sda6 111G 5.5G 100G 6% / /dev/sda1 454M 112M 315M 27% /boot /dev/sdb1 916G 142M 870G 1% /home # swap设置了6GB
找了一个台式机，全盘格式化后，全新安装的Ubuntu18.04.3 LTS
2 安装NVIDIA显卡驱动
spt@spt-ts:~$ lspci | grep -i vga
01:00.0 VGA compatible controller: NVIDIA Corporation GM206 [GeForce GTX 950] (rev a1)
显卡：gtx 950 驱动和CUDA对应版本好要求：

sudo add-apt-repository ppa:graphics-drivers/ppa sudo apt update ubuntu-drivers devices sudo apt install xserver-xorg-core sudo ubuntu-drivers autoinstall
安装了最新的显卡驱动

3 安装vim ssh服务
对项目没什么用，我主要是想用ssh连接这台机器。
sudo apt install vim openssh-server
4 安装CUDA v10.0
首先根据TensorFlow官方指导，先查好版本兼容性
https://tensorflow.google.cn/install/source 最新版本TensorFlow1.14.0，对应CUDA10.0和cuDNN7.4
.png)
1. Download and Run `sudo sh cuda_10.0.130_410.48_linux.run`
2. Download and Run Patch 1 (Released May 10, 2019)
顺便看清楚卸载方式。因为后面测试不同项目，需要不同版本。很有可能需要卸载，然后安装不同版本。
.............................................. To uninstall the CUDA Toolkit, run the uninstall script in /usr/local/cuda-10.0/bin uninstall_cuda_10.0.pl
安装后
spt@spt-ts:~$ df -ah Filesystem Size Used Avail Use% Mounted on sysfs 0 0 0 - /sys proc 0 0 0 - /proc udev 3.9G 0 3.9G 0% /dev devpts 0 0 0 - /dev/pts tmpfs 794M 2.0M 792M 1% /run /dev/sda6 111G 12G 94G 11% /
设置环境变量，在/etc/profile或~/.bashrc的文件后面添加
export PATH=/usr/local/cuda/bin${PATH:+:${PATH}}
export LD_LIBRARY_PATH=/usr/local/cuda/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
5 安装 cuDNN v7.4.2
Download cuDNN v7.4.2 (Dec 14, 2018), for CUDA 10.0
版本号必须匹配上面的CUDA版本
# 下载下面几个文件 Download cuDNN v7.4.2 (Dec 14, 2018), for CUDA 10.0
#cuDNN Library for Linux ---> cudnn-10.0-linux-x64-v7.4.2.24.tgz
#cuDNN Runtime Library for Ubuntu18.04 (Deb)
#cuDNN Developer Library for Ubuntu18.04 (Deb)
#cuDNN Code Samples and User Guide for Ubuntu18.04 (Deb)
cuDNN解压安装
spt@spt-ts:~/work/tensorflow$ pwd /home/spt/work/tensorflow spt@spt-ts:~/work/tensorflow$ tar xvf cudnn-10.0-linux-x64-v7.4.2.24.tgz spt@spt-ts:~/work/tensorflow$ sudo cp cuda/include/cudnn.h /usr/local/cuda/include spt@spt-ts:~/work/tensorflow$ sudo cp cuda/lib64/libcudnn* /usr/local/cuda/lib64 spt@spt-ts:~/work/tensorflow$ sudo chmod a+r /usr/local/cuda/include/cudnn.h /usr/local/cuda/lib64/libcudnn*
6 安装pip3 virtualenv
