Asking for those of us who have been using python and conda for a long time, and installed a bunch of packages in the base environment when we were first learning, and now want to clean things up to to have an empty base environment with maybe nothing more than numpy and matplotlib.

The ideal solution would in effect completely wipe the base environment but preserve other environments.

A few solutions mention conda install --revision 0, however when I look at my past revisions using conda list --revisions, I see a ton of packages listed. And I can confirm using conda list that at least a few of these packages were installed using default conda channels and have not been updated since revision 0.

I also wrote a bash script (which I have since lost) that went through and uninstalled each package. But this was rather unwieldy.

Any other recommendations to achieve a blank base environment?
