Linux(Ubuntu 18.04)上安装Anaconda步骤详解

Anaconda是最受欢迎的python数据科学和机器学习平台，用于大规模数据处理，预测分析和科学计算。Anaconda发行版附带了1,000多个数据包，conda命令行工具和Anaconda Navigator的桌面图形用户界面。

本教程将指导您完成在Ubuntu 18.04上下载和安装Anaconda Python Distribution。

下载Anaconda

在撰写本文时，Anaconda的最新稳定版本是5.3版本。

请选择 64-Bit (x86) Installer 进行下载链接: https://pan.baidu.com/s/1rNA9D8gaGHuIE0Ao_l5AQA 提取码: uecd 。尽量不要用python2.7，很多库已经不提供python2.7支持。

点击链接就会进行下载，同时会弹出信息收集框，直接关闭就好。

Microsoft VSCode is a streamlinedcode editor with support for development operations like debugging, taskrunning and version control.To install Visual Studio Code, you will need: - Administrator Privileges - Internet connectivityVisual Studio Code License: https://code.visualstudio.com/licenseDo you wish to proceed with the installation of Microsoft VSCode? [yes|no]>>> no添加"export PATH=/usr/local/anconda3/bin:$PATH" 到/etc/profile，这样所有用户都可以使用Anaconda python3.7了。上面的.bashrc在刚才安装时添加了如下内容：# added by Anaconda3 5.3.0 installer# >>> conda init >>># !! Contents within this block are managed by 'conda init' !!__conda_setup="$(CONDA_REPORT_ERRORS=false '/usr/local/anaconda3/bin/conda' shell.bash hook 2> /dev/null)"if [ $? -eq 0 ]; then \eval "$__conda_setup"else if [ -f "/usr/local/anaconda3/etc/profile.d/conda.sh" ]; then . "/usr/local/anaconda3/etc/profile.d/conda.sh" CONDA_CHANGEPS1=false conda activate base else \export PATH="/usr/local/anaconda3/bin:$PATH" fifiunset __conda_setup~/.bashrc# <<< conda init <<<

验证安装

通过重新登陆或者执行'source ~/.bashrc"加载环境变量。

$ conda info active environment : base active env location : /usr/local/anaconda3  shell level : 1 user config file : /home/andrew/.condarc populated config files :   conda version : 4.5.11 conda-build version : 3.15.1  python version : 3.7.0.final.0 base environment : /usr/local/anaconda3 (read only)  channel URLs : https://repo.anaconda.com/pkgs/main/linux-64    https://repo.anaconda.com/pkgs/main/noarch    https://repo.anaconda.com/pkgs/free/linux-64    https://repo.anaconda.com/pkgs/free/noarch    https://repo.anaconda.com/pkgs/r/linux-64    https://repo.anaconda.com/pkgs/r/noarch    https://repo.anaconda.com/pkgs/pro/linux-64    https://repo.anaconda.com/pkgs/pro/noarch  package cache : /usr/local/anaconda3/pkgs    /home/andrew/.conda/pkgs envs directories : /home/andrew/.conda/envs    /usr/local/anaconda3/envs  platform : linux-64  user-agent : conda/4.5.11 requests/2.19.1 CPython/3.7.0 Linux/4.15.0-36-generic ubuntu/18.04 glibc/2.27  UID:GID : 1000:1000  netrc file : None  offline mode : False$ pythonPython 3.7.0 (default, Jun 28 2018, 13:15:42) [GCC 7.2.0] :: Anaconda, Inc. on linuxType "help", "copyright", "credits" or "license" for more information.>>>
