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。

...
do you wish the installer to initialize anaconda3
in your /home/andrew/.bashrc ? [yes|no]
[no] >>> # 选择yes
initializing anaconda3 in /home/andrew/.bashrc
a backup will be made to: /home/andrew/.bashrc-anaconda3.bak
for this change to become active, you have to open a new terminal.
thank you for installing anaconda3!
===========================================================================
anaconda is partnered with microsoft! microsoft vscode is a streamlined
code editor with support for development operations like debugging, task
running and version control.
to install visual studio code, you will need:
 - administrator privileges
 - internet connectivity
visual studio code license: https://code.visualstudio.com/license
do 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"
 fi
fi
unset __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
