Conda Usage
Common Conda Commands
This section introduces some commonly used Conda commands.
View Help
Open the terminal and use the conda --help command to view the usage of all Conda commands.
radxa@device$
conda --help
The terminal will output information similar to the following:
usage: conda [-h] [-v] [--no-plugins] [-V] COMMAND ...
conda is a tool for managing and deploying applications, environments and packages.
options:
-h, --help Show this help message and exit.
-v, --verbose Can be used multiple times. Once for detailed output, twice for INFO logging, thrice for DEBUG logging, four times for TRACE
logging.
--no-plugins Disable all plugins that are not built into conda.
-V, --version Show the conda version number and exit.
commands:
The following built-in and plugins subcommands are available.
COMMAND
activate Activate a conda environment.
build Build conda packages from a conda recipe.
clean Remove unused packages and caches.
commands List all available conda subcommands (including those from plugins). Generally only used by tab-completion.
compare Compare packages between conda environments.
config Modify configuration values in .condarc.
content-trust Signing and verification tools for Conda
convert Convert pure Python packages to other platforms (a.k.a., subdirs).
create Create a new conda environment from a list of specified packages.
deactivate Deactivate the current active conda environment.
debug Debug the build or test phases of conda recipes.
develop Install a Python package in 'development mode'. Similar to `pip install --editable`.
doctor Display a health report for your environment.
env Create and manage conda environments.
export Export a given environment
index Update package index metadata files.
info Display information about current conda install.
init Initialize conda for shell interaction.
inspect Tools for inspecting conda packages.
install Install a list of packages into a specified conda environment.
list List installed packages in a conda environment.
metapackage Specialty tool for generating conda metapackage.
notices Retrieve latest channel notifications.
pack See `conda pack --help`.
package Create low-level conda packages. (EXPERIMENTAL)
remove (uninstall) Remove a list of packages from a specified conda environment.
rename Rename an existing environment.
render Expand a conda recipe into a platform-specific recipe.
repo See `conda repo --help`.
repoquery Advanced search for repodata.
run Run an executable in a conda environment.
search Search for packages and display associated information using the MatchSpec format.
server See `conda server --help`.
skeleton Generate boilerplate conda recipes.
token See `conda token --help`.
tos A subcommand for viewing, accepting, rejecting, and otherwise interacting with a channel's Terms of Service (ToS). This plugin
periodically checks for updated Terms of Service for the active/selected channels. Channels with a Terms of Service will need to
be accepted or rejected prior to use. Conda will only allow package installation from channels without a Terms of Service or with
an accepted Terms of Service. Attempting to use a channel with a rejected Terms of Service will result in an error.
update (upgrade) Update conda packages to the latest compatible version.
View Version Information
Open the terminal and use the conda --version command to check the Conda version.
radxa@device$
conda --version
The terminal will output information similar to the following:
conda 24.9.2
View Current Environment
Open the terminal and use the conda info command to view the current environment information.
radxa@device$
