I'm guessing that most installs will have /usr/bin/python as python2 or python3
At TACC we dearly wish we could remove /usr/bin/python but it’s needed at
system level.
We install our own python2 & python3 which become available under that name if
you load the appropriate module. Our installation links to MKL and has other
optimizations, as well as bumpy, scipy, & various other popular packages
installed.
My installation script does:
module load python3
if [ "${P4P}" -eq 1 ] ; then
export petsc4py="--download-petsc4py=yes --with-python=1
--with-python-exec=python3"
fi
FWIW.
