标签:python3.6 url article www 安装 切换 gcc man .gz 如何在Anaconda的python和系统自带的python之间切换 一般ubuntu下有三种python环境,1. 系统自带python2,3;在/usr/bin路径下;2. anaconda下安装的python;3. anaconda下创建的env环境 -当我们将:/home/dsp/anaconda3/bin添加到环境变量中时,用python命令得到时anaconda下的python环境; 然后如果时env环境,直接进入创建的虚拟环境即可; dsp@dsp-System-Product-Name:~/caffe-ssd$ echo $PATH - 如果时系统自带的环境,python2,3切换: linux下切换python2和python3 - 或者,待验证 ubuntu 下python环境的切换使用 标签:python3.6 url article www 安装 切换 gcc man .gz 原文地址:https://www.cnblogs.com/ranjiewen/p/9745593.html
