GTX1080主机准备好之后，就是配置深度学习环境了，这里选择了比较熟悉Ubuntu系统，不过是最新的Ubuntu 16.04版本，另外在Nvidia GTX1080的基础上安装相关GPU驱动，外加CUDA8.0，因为都比较新，所以踩了很多坑。
1. 安装Ubuntu16.04
不考虑双系统，直接安装 Ubuntu16.04，从 Ubuntu官方 下载64位版本: ubuntu-16.04-desktop-amd64.iso 。
在MAC下制作了 Ubuntu USB 安装盘，具体方法可参考: 在MAC下使用ISO制作Linux的安装USB盘 ，之后通过Bios引导U盘启动安装Ubuntu系统：
1）一开始安装就踩了一个坑，选择”Install Ubuntu”回车后过一会儿屏幕显示“输入不支持”，google了好多方案，最终和ubuntu对显卡的支持有关，需要手动添加显卡选项: nomodeset，使其支持Nvidia系列显卡，参考： Ubuntu安装时出现黑屏问题的解决 or How do I set ‘nomodeset’ after I’ve already installed Ubuntu?
2) 磁盘分区，全部干掉之前主机自带的Window 10系统，分区为 /boot, /, /home 等几个目录，同时把第二块4T硬盘也挂载了上去，作为数据盘。
3）安装完毕后Ubuntu 16.04的分辨率很低，在显卡驱动未安装之前，可以手动修改一下grub文件：
sudo vim /etc/default/grub
# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo’
#GRUB_GFXMODE=640×480
# 这里分辨率自行设置
GRUB_GFXMODE=1024×768
sudo update-grub
4）安装SSH Server，这样可以远程ssh访问这台GTX1080主机：
sudo apt-get install openssh-server
5）更新Ubuntu16.04源，用的是 中科大的源 ：
cd /etc/apt/
sudo cp sources.list sources.list.bak
sudo vi sources.list
把下面的这些源添加到source.list文件头部：
deb xenial main restricted universe multiverse
deb xenial-security main restricted universe multiverse
deb xenial-updates main restricted universe multiverse
deb xenial-proposed main restricted universe multiverse
deb xenial-backports main restricted universe multiverse
deb-src xenial main restricted universe multiverse
deb-src xenial-security main restricted universe multiverse
deb-src xenial-updates main restricted universe multiverse
deb-src xenial-proposed main restricted universe multiverse
deb-src xenial-backports main restricted universe multiverse
最后更新源和更新已安装的包：
sudo apt-get update
sudo apt-get upgrade
2. 安装GTX1080驱动
安装 Nvidia 驱动 367.27
sudo add-apt-repository ppa:graphics-drivers/ppa
第一次运行出现如下的警告：
Fresh drivers from upstream, currently shipping Nvidia.
## Current Status
We currently recommend: nvidia−361 nvidia-361 , Nvidia’s current long lived branch.
For GeForce 8 and 9 series GPUs use nvidia−340nvidia-340
For GeForce 6 and 7 series GPUs use nvidia−304nvidia-304
## What we’re working on right now:
– Normal driver updates– Investigating how to bring this goodness to distro on a cadence.
## WARNINGS:
This PPA is currently in testing, you should be experienced with packaging before you dive in here. Give us a few days to sort out the kinks.
Volunteers welcome! See also: https://github.com/mamarley/nvidia-graphics-drivers/

按回车继续或者 Ctrl+c 取消添加
回车后继续:
sudo apt-get update
sudo apt-get install nvidia-367
sudo apt-get install mesa-common-dev
sudo apt-get install freeglut3-dev
之后重启系统让GTX1080显卡驱动生效。
3. 下载和安装CUDA
