Environments

   Environments has a base pre-installed environment and one can create new environments.

   This is similar to Python's virtual environment which keeps separate versions of python and its libraries.

   When create a new environment, select Python/R and the language version. From command line:

      $conda create --name py35 python=3.5 

Then you can activate the environment. This will switch the command line to the py35 environment.

    $conda activate py35

To install libraries, e.g.

    $python -m pip install matplotlib

Channels

   Channel points to a conda repository. There is usually a default repository point to https://repo.anaconda.com/

   One can add new repository, e.g. conda cloud https://conda.anaconda.org

Install packages

   from Anaconda navigator, one can search for packages and then install them. those packages will be applied to your selected environment only.

   from command line:

      $conda install -n env_name -c conda-forge xyz_package.

   -n is for environment name, -c is the channel

Run editor

   from Anaconda navigator under Home section, there is a list of applications for launch / install

   Select to run VS Code, Spyder, Jupyter Notebook, etc.

   The editor will use the selected environment
