(do this before installing packages)

conda activate ENVNAME

Quick Start

Tip: It is recommended to create a new environment for any new project or workflow.

Channels and Packages

Tip: Package dependencies and platform specifics are automatically resolved when using conda.

Tip: List environments at the beginning of your session. Environments with an asterisk are active.

Working with Conda Environments

cross-platform compatible

conda export --from-history>ENV.yml

platform + package specific

conda export ENVNAME>ENV.yml

platform + package + channel specific

conda list --explicit>ENV.txt

create environment with Python version

conda create -n ENVNAME python=3.10

clone environment

conda create --clone ENVNAME -n NEWENV

rename environment

conda rename -n ENVNAME NEWENVNAME

delete environment by name

conda remove -n ENVNAME --all

list revisions made to environment

conda list -n ENVNAME --revisions

restore environment to a revision

conda install -n ENVNAME --revision NUMBER

uninstall package from specific channel

conda remove -n ENVNAME -c CHANNELNAME PKGNAME

get help for any command

conda COMMAND --help

get info for any package

conda search PKGNAME --info

run commands w/o user prompt

eg, installing multiple packages

conda COMMAND ARG --yes

conda install PKGNAME1 PKGNAME2 --yes

remove all unused files

conda clean --all

examine conda configuration

conda config --show

from a .yml file

conda env create -n ENVNAME --file ENV.yml

from a .txt file

conda create -n ENVNAME --file ENV.txt

Environment Management

Tip: Specifying the environment name confines conda commands to that environment.

Exporting Environments

Recommendation: Name the export file “environment.” Environment name will be preserved.

Additional Hints

Importing Environments

Tip: When importing an environment, conda resolves platform and package specifics.
