今天是初五，民間有破五的習俗，簡單來說就是說該工作啦。
回顧研究生畢業的一年半，期間從事過桌面應用開發、CAN\串口開發、無人機目標檢測開發、爬蟲、數據工程、大數據系統運維等。研究生期間學的深度學習也好久沒再接觸，自己配的深度學習機器（菜鳥攢機之深度學習(上)）（菜鳥攢機之深度學習(下)）在家吃灰了好久，當時還是卡皇的GTX 1080也已經被1080 Ti、2080、2080 Ti取代，TensorFlow也從1.8迭代到了2.1，Caffe、MXNet、Torch逐漸退出人們視野，形成TensorFlow、PyTorch雙雄爭霸的局面，Python2也退出歷史舞臺，Python3迭代到3.8。隨着工作中的不斷學習積累，我也從Linux、Python小白中的小白，成長爲能夠獨立處理一些技術問題的中級用戶，對Linux、Python也有了一些更深刻的認識。
雖然當前的工作主要集中在數據工程、後端、爬蟲，但我還是更喜歡深度學習，那種從Top1 accuracy、Top5 accuracy曲線逐漸上升，Loss曲線逐漸下降帶來的心理滿足感是別的技術所無法取代的。趁着這兩天不忙，打算把家裏的機器重新部署一次深度學習環境，並把過程記錄下來，希望能幫到更多人。
願疫情早日結束！！！！！！！！！！！！！
系統環境：
- Ubuntu 18.04.3 最小安裝版
- i7-7700K
- NVIDIA GTX 1080
- 16G RAM
- 256 SSD
目錄
1 Ubuntu系統安裝
1.1 製作安裝U盤
2020-01-29
從Ubuntu官網下載ISO鏡像
使用Startup Disk Creator圖形化工具製作
如果找不到，則通過
>>> sudo apt install usb-creator-gtk
使用Refus圖形化工具
使用Etcher圖形化工具
1.2 安裝系統
按步驟安裝即可
我建議是最小化安裝，好多沒用的軟件如：libreoffice就不會裝上去，節省空間
切記在BIOS將secure boot關閉，否則即便安裝成功，啓動也會出問題。
2 配置基礎環境

2.3 安裝搜狗輸入法
官網下載安裝包，雙擊安裝，再通過settings→Region&Language→Manage Installed Language將輸入法框架從iBus換成fcitx
重新啓動
到這裏就能切換出搜狗拼音了
如果使用過程中出現候選框亂碼現象：
則通過
>>> cd ~/.config
>>> sudo rm -rf SogouPY* sogou*
再註銷重啓就恢復正常了
開啓ssh遠程連接
ssh分爲客戶端與服務端
默認安裝有客戶端openssh-client
想要遠程連接到本機，需要安裝openssh-server
通過以下命令查看本機ssh相關進程
>>> dpkg -l | grep ssh
ii libssh-gcrypt-4:amd64 0.8.0~20170825.94fa1e38-1ubuntu0.5 amd64 tiny C SSH library (gcrypt flavor)
ii openssh-client 1:7.6p1-4ubuntu0.3 amd64 secure shell (SSH) client, for secure access to remote machines
>>> sudo apt install openssh-server
>>> dpkg -l | grep ssh

ii ssh-import-id 5.7-0ubuntu1.1 all securely retrieve an SSH public key and install it locally
開啓、關閉、查看狀態
>>> systemctl start sshd.service

2.5 安裝pip3
關於python3-pip和get-pip.py兩種安裝方法早有討論：https://github.com/pypa/pip/issues/5599
目前的結論是，通過apt install python3-pip方式安裝的是針對debin系統的pip，版本比較低，目前僅爲9.0.1，而通過get-pip.py方式安裝的爲pypa提供的最新版pip，目前爲20.0.2。但大部分人推薦使用python3-pip，而非最新的pip。如果不慎兩種方法都安裝了，可通過以下命令進行重置：
>>> python3 -m pip uninstall pip setuptools wheel
>>> sudo apt-get --reinstall install python3-setuptools python3-wheel python3-pip
但考慮到加速pip包下載，需要使用高版本pip纔有的config功能，因而：
# 升級至最新版
>>> pip3 install -i https://pypi.tuna.tsinghua.edu.cn/simple -U pip
>>> pip3 --version
WARNING: pip is being invoked by an old script wrapper. This will fail in a future version of pip.
Please see https://github.com/pypa/pip/issues/5599 for advice on fixing the underlying issue.
To avoid this problem you can invoke Python with '-m pip' instead of running pip directly.
pip 20.0.2 from /home/microfat/.local/lib/python3.6/site-packages/pip (python 3.6)
# 通過設置config改變pip源爲清華源
>>> pip3 config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple
默認源：
https://pypi.python.org/simple
配置文件位置：~/.config/pip/pip.conf
參考：https://github.com/pypa/pip/issues/5599#issuecomment-416318017
2.6 安裝git、zsh、oh-my-zsh
略
如果在安裝oh-my-zsh中存在下載過慢的問題，可通過socks5加速，前提是SS已經部署好了
>>> sh -c "$(curl --socks5 127.0.0.1:1080 -fsSL https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"
