08 Feb 2017Here is a short collection of commands and solutions for Anaconda with Python that I frequently tend to use.
Quick and Useful Commands
conda -v
See current version of Anacondaconda install [package]
Install package to current environmentconda install -c [channel] [package]
Install package with a specific channelconda search python
See available versions of Pythonconda list
List all packages installed in current environmentconda update conda
Update Anacondaconda info -e
orconda env list
List all installed enviromentsconda env export > environment.yml
Export active environmentconda env create -f environment.yml
Create environment from specificationconda install --rev 1
Restore root environment to its state after installationconda remove --name myenv --all
Remove an environment
How to use Virtual Environments in Anaconda?
In Anaconda it is possible to run different environments and versions of Python which helps when working with conflicting packages or packages that are for example not updated and available for newer Python versions. In order to install a new environment with the name py35
in Anaconda simply use
conda create -n py35 python=3.5 anaconda
This creates a new environment installed in the /envs/py35
directory inside the Anaconda directory. If you need to install further packages to the created virtual environment you can install it by
conda install -n py35 [package]
This virtual enviroment can be now activated with
source activate py35
or on windows with activate py35
. You can then deactivate the environment with
source deactivate py35
or on windows with deactivate py35
. And finally if you do not need the environment anymore, it can be deleted with
conda remove -n py35 -all
Here is more information on how to manage python and on how to manage packages in Anaconda.
Anaconda Base Environment
Check if Anaconda base environment is enabled:
conda config --show | grep auto_activate_base
To disable the Anaconda base environment:
conda config --set auto_activate_base False
Reset Anaconda Root Environment
Remove root environment and conda
command:
conda install --revision 0
Restore root environment to state after first installation:
conda install --revision 1
To list revisions, type:
conda list --revision

Export Anaconda Environment
Export the current Anaconda environment:
conda env export \
--from-history \
--no-builds > myenv.yml
The --no-builds
flag prevents the inclusion of platform-specific build IDs. When using --from-history
(introduced in Conda 4.7.12), Conda will only export packages and versions which you have explicitly installed using conda install.
This environment can be then installed with:
conda env create \
--name myenv \
--file myenv.yml
Here is a script to bulk export all conda environments in your system:
#!/bin/bash
set -e
conda activate
for conda_env in $$(conda env list | cut -d" " -f1 | tail -n+4); do
echo $$conda_env
conda activate $$conda_env
conda env export \
--from-history \
--no-builds > "$${conda_env}.yml"
done
conda activate
This needs to be run with source script.sh
.
