Anaconda是最受歡迎的python資料科學和機器學習平臺，用於大規模資料處理，預測分析和科學計算。Anaconda發行版附帶了1,000多個數據包，conda命令列工具和Anaconda Navigator的桌面圖形使用者介面。

本教程將指導您完成在Ubuntu 18.04上下載和安裝Anaconda Python Distribution。

請選擇 Linux-x86_64.sh" target="_blank" rel="nofollow,noindex">64-Bit (x86) Installer 進行下載，儘量不要用python2.7，很多庫已經不提供python2.7支援。

點選連結就會進行下載，同時會彈出資訊收集框，直接關閉就好。

===========================================================================

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

新增“export PATH=/usr/local/anconda3/bin:$PATH“ 到/etc/profile，這樣所有使用者都可以使用Anaconda python3.7了。

上面的.bashrc在剛才安裝時添加了如下內容：

# 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 <<<

驗證安裝

通過重新登陸或者執行'source ~/.bashrc"載入環境變數。
