Kubeflow

Kubeflow 的 Notebook 功能是一种方便的方式，让用户可以在 Kubernete s集群上创建和管理交互式的 Jupyter Notebook。用户可以通过 Kubeflow Dashboard 或者 kubectl 命令来创建和管理 Notebook 服务器。Notebook 服务器是一个 Kubernetes Deployment，运行了一个单独的 Notebook 实例，并且可以配置不同的资源和环境。用户可以在 Notebook中运行各种数据科学和机器学习的代码，以及使用 Kubeflow 提供的其他组件和服务。

1. 配置系统环境

配置 .bashrc，命令如下：

cp files/.bashrc ~/.bashrc
source ~/.bashrc

具体的推荐 .bashrc，请参考最后部分。

配置 conda 环境，安装 Miniconda，其它版本 Miniconda 或者 Anaconda 均可，命令如下：

wget https://repo.anaconda.com/miniconda/Miniconda3-py38_23.3.1-0-Linux-x86_64.sh
bash files/Miniconda3-py38_23.3.1-0-Linux-x86_64.sh
source ~/.bashrc

实际下载地址：https://repo.anaconda.com/miniconda/，约98.8M

推荐使用 Python3.8 版本

配置 Conda 源，即 .condarc：

cp files/.condarc ~/.condarc

具体的推荐 .condarc，请参考最后部分。

配置 pip 源，即 .pip/：

mkdir ~/.pip
vim ~/.pip/pip.conf

# 文件内容如下：

# This file has been autogenerated or modified by NVIDIA PyIndex.
# In case you need to modify your PIP configuration, please be aware that
# some configuration files may have a priority order. Here are the following 
# files that may exists in your machine by order of priority:
#
# [Priority 1] Site level configuration files
#       1. `/opt/conda/pip.conf`
#
# [Priority 2] User level configuration files
#       1. `/root/.config/pip/pip.conf`
#       2. `/root/.pip/pip.conf`
#
# [Priority 3] Global level configuration files
#       1. `/etc/pip.conf`
#       2. `/etc/xdg/pip/pip.conf`

[global]
no-cache-dir = true
index-url = https://pypi.tuna.tsinghua.edu.cn/simple/
extra-index-url = https://pypi.ngc.nvidia.com
trusted-host = pypi.tuna.tsinghua.edu.cn pypi.ngc.nvidia.com

创建 conda 环境：

conda create -n torch-def  # 创建空环境

# 或者，复制已有环境，时间较长，建议慢慢等待
conda create -n torch-def --clone conda_envs/torch-def/

测试 PyTorch 环境：

import torch

# 测试环境
ngpu= 1
# Decide which device we want to run on
device = torch.device("cuda:0" if (torch.cuda.is_available() and ngpu > 0) else "cpu")
print("驱动为：",device)
print("GPU型号： ",torch.cuda.get_device_name(0))


# 测试张量
import torch
import time
print(torch.__version__)
print(torch.cuda.is_available())

a = torch.randn(100, 10)
b = torch.randn(10, 200)
device = torch.device('cuda')
a = a.to(device)
b = b.to(device)
c = torch.matmul(a, b)
print(a.device, c.device)

2. 创建 Notebook

Kubeflow 创建 Notebook：

Notebooks

在 New notebook 页面，依次修改 Name、Image、CPU&Memory、GPU型号：

GPU

其余，选择默认，点击 LAUNCH 即可。

Launch

3. 参考

推荐的.bashrc，如下：

# ~/.bashrc: executed by bash(1) for non-login shells.
# see /usr/share/doc/bash/examples/startup-files (in the package bash-doc)
# for examples

# If not running interactively, don't do anything
case $- in
    *i*) ;;
      *) return;;
esac

# don't put duplicate lines or lines starting with space in the history.
# See bash(1) for more options
HISTCONTROL=ignoreboth

# append to the history file, don't overwrite it
shopt -s histappend

# for setting history length see HISTSIZE and HISTFILESIZE in bash(1)
HISTSIZE=1000
HISTFILESIZE=2000

# check the window size after each command and, if necessary,
# update the values of LINES and COLUMNS.
shopt -s checkwinsize

# If set, the pattern "**" used in a pathname expansion context will
# match all files and zero or more directories and subdirectories.
#shopt -s globstar

# make less more friendly for non-text input files, see lesspipe(1)
[ -x /usr/bin/lesspipe ] && eval "$(SHELL=/bin/sh lesspipe)"

# set variable identifying the chroot you work in (used in the prompt below)
if [ -z "${debian_chroot:-}" ] && [ -r /etc/debian_chroot ]; then
    debian_chroot=$(cat /etc/debian_chroot)
fi

# set a fancy prompt (non-color, unless we know we "want" color)
case "$TERM" in
    xterm-color|*-256color) color_prompt=yes;;
esac

# uncomment for a colored prompt, if the terminal has the capability; turned
# off by default to not distract the user: the focus in a terminal window
# should be on the output of commands, not on the prompt
#force_color_prompt=yes

if [ -n "$force_color_prompt" ]; then
    if [ -x /usr/bin/tput ] && tput setaf 1 >&/dev/null; then
        # We have color support; assume it's compliant with Ecma-48
        # (ISO/IEC-6429). (Lack of such support is extremely rare, and such
        # a case would tend to support setf rather than setaf.)
        color_prompt=yes
    else
        color_prompt=
    fi
fi

if [ "$color_prompt" = yes ]; then
    PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '
else
    PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w\$ '
fi
unset color_prompt force_color_prompt

case "$TERM" in
xterm*|rxvt*)
    PS1="\[\e]0;${debian_chroot:+($debian_chroot)}\u@\h: \w\a\]$PS1"
    ;;
*)
    ;;
esac

# enable color support of ls and also add handy aliases
if [ -x /usr/bin/dircolors ]; then
    test -r ~/.dircolors && eval "$(dircolors -b ~/.dircolors)" || eval "$(dircolors -b)"
    alias ls='ls --color=auto'

alias alert='notify-send --urgency=low -i "$([ $? = 0 ] && echo terminal || echo error)" "$(history|tail -n1|sed -e '\''s/^\s*[0-9]\+\s*//;s/[;&|]\s*alert$//'\'')"'

# Alias definitions.
# You may want to put all your additions into a separate file like
# ~/.bash_aliases, instead of adding them here directly.
# See /usr/share/doc/bash-doc/examples in the bash-doc package.

if [ -f ~/.bash_aliases ]; then
    . ~/.bash_aliases
fi

# enable programmable completion features (you don't need to enable
# this, if it's already enabled in /etc/bash.bashrc and /etc/profile
# sources /etc/bash.bashrc).
if ! shopt -oq posix; then
  if [ -f /usr/share/bash-completion/bash_completion ]; then
    . /usr/share/bash-completion/bash_completion
  elif [ -f /etc/bash_completion ]; then
