I plan to switch to Python3-base Sagemath (as recenthy requested on this list) at least in order to be able to report my results and corner cases resulting from my (admittedly peculiar) use of Sage.
So far, the instructions given in the
FAQ worked. Perusing the
sage-release list hinted me about make
ptest-python3. So I wonder how to run (the equivalents of) ptestlong and/arr testalllong without bumping on a whole lot of known unsupported cases.
