Intro

This repo records some steps to initialize my faviorate work environment (including oh-my-zsh, conda, pytorch) on a new Ubuntu machine.

Commonly used commands

df -h          # see the memory usage of each disk
du -d 1 -h     # see the memory usage of a folder

Clash

quick links: Tutorial, clash

# download
unzip Clash.zip    # online link is not supported anymore. Use our zip file.
wget -O config.yaml [代理商提供的订阅链接]    # your vpn config

# run
cd Clash
./clash -d .

# Open another terminal and set proxy for the system. Add into ~/.bashrc or ~/.zshrc to make it permanent.
export https_proxy=http://127.0.0.1:7890 http_proxy=http://127.0.0.1:7890 all_proxy=socks5://127.0.0.1:7891

# cancel proxy
unset https_proxy
unset http_proxy
unset all_proxy

Zsh

quick-links: oh-my-zsh, zsh-autosuggestions, zsh-syntax-highlighting

Install

# install oh-my-zsh. Need Clash!
sh -c "$(wget https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh -O -)"

# install zsh-autosuggestions
git clone https://github.com/zsh-users/zsh-autosuggestions ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-autosuggestions

To use zsh as the default one, add the following two lines to ~/.bash_profile (or ~/.bashrc) and reconnect the server.

export SHELL=`which zsh`
[ -z "$ZSH_VERSION" ] && exec "$SHELL" -l

Install useful plugins:

git clone https://github.com/zsh-users/zsh-autosuggestions ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-autosuggestions
git clone https://github.com/zsh-users/zsh-syntax-highlighting ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-syntax-highlighting

And set the following lines in ~/.zshrc:

plugins=(
    git
    zsh-autosuggestions
    zsh-syntax-highlighting
)

Change theme

Recommend powerlevel10k.

Use source ~/.zshrc to make the changes effective.

Conda

quick-links: miniconda, Anaconda

# Download Miniconda (Linux, python 3.8)
wget https://repo.anaconda.com/miniconda/Miniconda3-py38_4.12.0-Linux-x86_64.sh

# Install 
sh Miniconda3-py38_4.12.0-Linux-x86_64.sh

# Refresh .zshrc
source ~/.zshrc

To create and remove environments,

# create new envs
conda create -n ${ENV_NAME}

# remove envs
conda remove -n ${ENV_NAME}

Tsinghua Mirror

Quick-links: pip

# pip 
pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple

# conda 
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/

CUDA Toolkit 11.8

Recommend this blog.

pytorch

quick-links: pytorch

Personal preference: 2.0.1+cu118

NOTE: If you are using Tsinghua Mirror through pip to install pytorch, the default version of torch is CUDA10.2. It may have problem to run on machine with CUDA 11.0+ !

NOTE: If you are using Tsinghua Mirror through conda to install pytorch, remove '-c pytorch'. (But it may fail to find the suitable version)

Recommended way:

Use Clash and move to pytorch_all_versions and choose the suitable link to run.

Another possible way:

Choose suitable version and download .whl file from here
Directly install from .whl file

# stable version 1.9.1+cu111 (Linux, python 3.8)
wget https://download.pytorch.org/whl/cu111/torch-1.9.1%2Bcu111-cp38-cp38-linux_x86_64.whl

# install from .whl file
pip install torch-1.9.1+cu111-cp38-cp38-linux_x86_64.whl

Git

To connect to github, first run

ssh-keygen

to generate keys. Then put the public key (.ssh/id_rsa.pub) to -> Settings -> SSH and GPG keys

Then, write the following lines to ~/.ssh/config

Host github.com
    Hostname ssh.github.com
    Port 443
    User git

Now you can pull codes. To push codes, you also need

git config --global user.email {$YOUR_EMAIL}
git config --global user.name {$YOUR_NAME}
