Anaconda exposes two important command-line tools, conda and source.
How To Create And Use A Virtual Environment
This assumes you have installed anaconda and conda is available on your path.
First, create a new environment:
$ conda create -n <your environment name>
Now activate this environment:
$ source activate <your environment name>
Install your required packages:
$ conda install -n <your environment name> <package>
Now you can run your python code!
When finished, you can deactivate your virtual environment with:
$ source deactivate
Listing All Local Environments
Use the following command to list all local environments:
$ conda env list
The currently active environment will have an asterisk after it’s name.
Installing Non-Conda Packages
Non-conda packages can be installed into the current environment with other Python package managers such as pip:
$ pip install <package name>
As long as a Anaconda environment is active, pip will install to the current environment only.
