I am using the conda package manager – a lot. By now I have quite a few environments and a lot of downloaded packages taking a lot of space on my SSD. An obvious path to free some of that space is to use the command
conda env export > environment.yml
from https://conda.io/docs/user-guide/tasks/manage-environments.html#exporting-the-environment-file to export which packages my old, inactive projects use(d) and then delete these environments. As far as I understand, this should free some of the space in
anaconda2/envs/, but not in
anaconda2/pkgs/. How do I get rid of these packages? Also, I suspect that there might be quite a few packages still sitting around, to which no environment is linking to – could that happen?
- In general: What is the best way to reduce the space taken up by conda?
- How do I get rid of packages that no environment is using anymore? How do I prune my packages? I am searching for something like
sudo apt-get autoremovefrom Ubuntu/Debian.
Now we will see solution for issue: How to free disk space taken up by (ana)conda?
You can free some space with:
conda clean --all
cleanRemove unused packages and caches.
Conda already use symlinks when possible for packages. So, not much to improve here, I guess.
Ok, thanks, but I would like to know “not for a specific environment, but in general” – for all environments.
You can list all packages in all envs with a few lines of Python:
import os import subprocess for env in os.listdir('/Users/me/miniconda3/envs'): subprocess.call(['conda', 'list', '-n', env])
