Multiple mkl packages installed in anaconda

Question

I've just observed that there are tree different version of mkl package installed on my computer.

du -sh */
417M    mkl-2017.0.1-0/
407M    mkl-2017.0.3-0/
557M    mkl-2018.0.1-hfbd8650_4/
526M    mkl-2018.0.2-1/ 

I know that mkl package included in numpy and pandas install but I didn't expect it influence the binary size so dramatically.

Can I delete any of this package or somehow reduce it size?

Answer 1

The command conda clean --all is supposed to only remove the packages and cache you don't use. You can run it to decrease the size conda packages take on your computer, or use conda clean --all --dry-run just to see which packages would end up being uninstalled if you run the clean command.
