I am trying to download the database of reflexive 4d lattice polytopes using the command
!sage -i polytopes_db_4dbut I get the error:
make: *** No rule to make target 'all-toolchain'. Stop.Not sure what this means or how to get around it, so any help or explanation would be welcome. I am relatively new to SAGE so sorry if it is something obvious!
This package is an "old-style spkg" package.
This means it cannot be installed using sage -i like "new-style spkg" packages.
The workaround is to install it with sage -p.
Quit Sage and in a terminal, run
$ sage -p polytopes_db_4dThis involves downloading the package which contains a huge (~8 GB) database, so it might take a while.
Once this is done, restart Sage and you can follow the SageMath documentation on using the palp_database of reflexive Hodge 4-polytopes:
sage: version()
'SageMath version 8.4, Release Date: 2018-10-17'
sage: from sage.geometry.polyhedron.palp_database import Reflexive4dHodge
sage: ref = Reflexive4dHodge(1, 101)
sage: next(iter(ref)).Vrepresentation()
(A vertex at (-1, -1, -1, -1),
A vertex at (0, 0, 0, 1),
A vertex at (0, 0, 1, 0),
A vertex at (0, 1, 0, 0),
A vertex at (1, 0, 0, 0))Asked: 6 years ago
