Setting up a new environment#

Mamba discourages the installation of anything in the base environment. Instead, it is recommended to make new environments to install packages to. In my installation, I have four additional ones:

Matt's Python Environments

  • daily : a scratch environment for Python work which doesn’t have many package requirements.

  • playground : an experimental scratch environment for playing with new packages, which won’t impact my daily use.

  • arim-env : an environment for a major project, containing (amongst other things) a working arim installation.

  • ssgb : an environment for a major project, containing packages for working with Gaussian Processes.

To set up a new environment, use the following command template:

mamba create -n <environment_name> <list of packages...>

After creation, activate this environment to use it with

mamba activate <environment_name>

and deactivate an active environment with

mamba deactivate

Install a new package to an active environment from a specific channel (e.g. conda-forge) with

mamba install <package1> -c <channel> ...

Finally, to delete an environment, use

mamba env remove -n <environment_name>
