All of the major scientific libraries and core packages are dropping python 2 support. Are there legacy versions of these packages being maintained or at least preserved?
Is this even a valuable use case?
Install Python 2.7, which is by does with pip. Upgrade pip if you want, which will get you the last version of pip that supports Python 2 (the old versions haven't gone away, new versions just don't support py2 and won't show up when upgrading on py2). Install the needed scientific libraries. Run code.

AFAIK, there is no plan to remove py2 packages from pyPI.
If not, it’s a good argument for vendoring dependencies when publishing scientific code.
