PALP database for 4D reflexive polytopes?

[Ursula Whitcher]

I tried to install the PALP database for four-dimensional reflexive polytopes on the SageMath cloud, following the documentation at

http://doc.sagemath.org/html/en/reference/geometry/sage/geometry/polyhedron/palp_database.html ,

which suggests the shell command

sage -i polytopes_db_4d

.

This didn't work.  I'm not sure whether the failure implies a problem with the database, or with the place I'm trying to put it on the cloud (this is a standard Sage installation, not a development version, on a members-only server without extra internet access enabled).  Here's the full terminal output: 

***

Any ideas?

It looks (below) like two problems:
1. You don't have permission to write (create/change files) in the directory tree SAGE_ROOT.
2. This: "Error: package 'polytopes_db_4d' not found"

I'm not sure how to overcome the first. If sage is installed on a multiuser system, in an admin/root-owned tree, you are stuck, I think. Check with the system admins.

As for the second, you don't seem to have enough information below to figure out why the package is not found. Are you sure the name is complete and correct? The link you include (above) only seems to give use examples, not install instructions.

Justin is right, the question is precisely: how Sage was installed on
this computer?

It's a bog-standard SageMathCloud installation.  Sounds like creating a development version of Sage in this project is the next trouble-shooting step?

I would be curious to know whether the command 

sage -i polytopes_db_4d

works for anyone who has a personal installation of Sage handy.

trying it now - the download is over 8Gb in size!

yes, it does install for me, and work, too:

all the tests in geometry/polyhedron/palp_database.py pass.

Great, thanks for checking!  I'll take any further questions to the SageMathCloud list, as it sounds like my difficulties stem from that framework.
