Managing Environments with Miniconda

The previous article explains how to properly install and configure Miniconda. This article will explain how to manage your environments.

Creating a Virtual Environment

conda create -n <myenv> python=<3.7> pip -y

This command will create a virtual environment with the following properties:

• -n myenv You can choose any name you want here
• python=3.7 you can set the version to be whatever you want such as 2.7 (if you don't specify a version it will choose the latest)
• -y this just preemptively answers yes to creating the environment

Activating a Virtual Environment

conda activate <myenv>

Deactivating a Virtual Environment

conda deactivate <myenv>

Listing Available Environments

conda env list

Removing an Environment

conda remove --name <myenv> --all

Cloning an Environment

conda create --name <myclone> --clone <myenv>

Removing PS1 Prompt

conda config --set changeps1 false

To re-enable:

conda config --set changeps1 true

Searching for packages

conda search <package-name>

Sharing an environment

• First export the environment

conda env export > environment.yml

• Now install in another Anaconda Environment Manager

conda env create -f environment.yml

Installing Packages & Pinning Versions

• With conda (=)

conda install <package>=<version-number>

• With pip (==)

pip install <package>==<version-number>
