As a user of Anaconda python I have been receiving (Ubuntu) system warnings of low free space in my home directory. Investigating what was causing this I found out that Anaconda python had several versions of each package. The overall size of the

conda clean --all conda update conda # just to make sure nothing is broken and # your environment is updated source activate <your-environment> conda update --all conda clean --all
