目前Anaconda默认安装的python版本为3.6或者2.7
如果要安装Python3.5，可以根据需要配置，配置方法见页面：我用方法2尝试成功
There are three ways to get Anaconda with Python 3.5:
- We recommend that you download the latest version of Anaconda and then make a Python 3.5 environment.
- Or download the latest version of Anaconda and run this command to install Python 3.5 in the root environment:
conda install python=3.5 - Or download the most recent Anaconda that included Python 3.5 by default, Anaconda 4.2.0. You can download it from our archive. Scroll down the page until you find version 4.2.0 for your platform.
Ubuntu下安装Anaconda时，按照方法3下载对应的Python3.5版本，sh文件
在文件目录下运行指令即可安装：如果安装不成功，可尝试 bash xxxx.sh
./xxxx.sh
Spyder可直接再terminal运行，可通过conda list查看是否有安装。
安装完后，可以通过terminal下运行python2和python3分别运行自带的2.7和新安装的3.5
