The environment management function of creating a python environment
Conda allows us to install several different versions of Python at the same time and switch freely. For the above installation process, for example, we used the installation package corresponding to Python 2.7 above, then Python 2.7 is the default environment. If we need to install Python 3.6, we need to do the following:
conda create --name python36 python=3.6
source activate python36You can see that there is python36 in the anaconda3/envs/ directory
Switch python environment
If you want to return to the default python 2.7 environment, run
deactivate python34 # for Windows
source deactivate python34 # for Linux & Mac
