Miniconda

The fastest way to obtain conda is to install Miniconda, a mini version of Anaconda that includes only conda and its dependencies. If you prefer to have conda plus over 7,500 open-source packages, install Anaconda.

Installation

On macOS it's easiest to use Homebrew for the task:

brew install miniconda

See project documentaiton for the installer script.

Managing Environments

Create an environment

The following two tabs illustrate how to create an environment and install packages manually with several commands while the other shows how to build an environment based on specifications found in a YAML file.

# Create conda environment and activate it
conda create --name myenv
conda activate myenv
# Install latest Python 3.9.x
conda install python=3.9
# Install some package and its depepdencies
pip install mkdocs-material
# Create a yaml file specifiying the details of the env to create
cat <<EOD >~/environment.yml
name: myenv
dependencies:
  - python=3.9
  - pip:
      - mkdocs-material
EOD
# the -f option can even be ommitted if the environment file is named
# environment.yaml and is found within current workig directory
conda create [-f environment.yml]

Add environment.yml to git repo

When having a python environemnt for project, it's good practice to have the specification in a file environment.yml toplevel in the git repo of the project. Like this, you document what needs to be install and you (and your contributors) can fire up the evironment by just cloning the repo and running conda create within the toplevel directory. Done.

Managing environments

Further commands regarding the management of environments outlined in the [documentation] in good details. Have a look there!
