Conda Cheet Sheet#

Quick Start#

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

verify conda install and check version	conda info
update conda in base environment	conda update -n base conda
install latest anaconda distribution	conda install anaconda=VERSION
create a new environment	conda create –name ENVNAME
activate environment	conda activate ENVNAME

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

list installed packages	conda list
list installed packages with source info	conda list –show-channel-urls
update all packages	conda update –all
install a package from specific channel	conda install -c CHANNELNAME PKG1 PKG2
install specific version of package	conda install PKGNAME=3.1.4
install a package from specific channel	conda install CHANNELNAME::PKGNAME
install package with AND logic	conda install “PKGNAME>2.5,<3.2”
install package with OR logic	conda install “PKGNAME [version=’2.5\|3.2’]”
uninstall package	conda uninstall PKGNAME
view channel sources	conda config –show-sources
add channel	conda config –add channels CHANNELNAME
set default channel for pkg fetching	conda config –set channel_priority strict

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

list all environments and locations	conda env list
list all packages + source channels	conda list -n ENVNAME –show-channel-urls
install packages in environment	conda install -n ENVNAME PKG1 PKG2
remove package from environment	conda uninstall PKGNAME -n ENVNAME
update all packages in environment	conda update –all -n ENVNAME

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

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

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

cross-platform compatible	conda env export –from-history>ENV.yml
platform + package specific	conda env export ENVNAME>ENV.yml
platform + package + channel specific	conda list –explicit>ENV.txt

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

from a .yml file	conda env create -n ENVNAME –file ENV.yml
from a .txt file	conda create -n ENVNAME –file ENV.txt

get help for any command	conda COMMAND –help
get info for any package	conda search PKGNAME –info
run commands w/o user prompt	conda COMMAND ARG –yes conda install PKG1 PKG2 –yes
remove all unused files	conda clean –all
examine conda configuration	conda config –show
