[sage-devel] Re: [sage-cloud] Sympy needs to be updated in SMC and Sage
Yes, that error is due to sympy-0.7.6 bundling mpmath.
That's why patches were needed with 0.7.5 in Sage. So,
either William should install git master using pip,
or apply the existing patches in build/ to 0.7.6.

I had forgotten about those when I posted this. 17 (scons) only exists because of 18 (polybori) and csage, although there has been some work to move off of scons for csage. I'm not really familiar with the polybori situation, other than from the outside, the project appears to be dead, so we would have to handle that somehow. Certainly, most of sage *should* be usable without polybori, so we *should* be able to get something up and running without it (considering how messed up the imports are in sage though, it wouldn't surprise me if it would take a ton of work to make sage usable without polybori). -- > You received this message because you are subscribed to the Google Groups > "sage-devel" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to sage-devel+unsubscr...@googlegroups.com. > To post to this group, send email to sage-devel@googlegroups.com. > Visit this group at http://groups.google.com/group/sage-devel. > For more options, visit https://groups.google.com/d/optout. > -- Andrew -- You received this message because you are subscribed to the Google Groups "sage-devel" group.

[sage-devel] Python 3 focused Sage Days
As an alternative to the Bug Days William mentioned, we could hold a workshop focused on porting Sage to Python 3 (this has apparently been a frequent request for SMC). All our dependencies have proper support for Python 3, so the main effort at this point in time is porting the Sage library. A lot of effort has already gone into fixing non-Python 3 compatible syntax and functionality (see #15980 and #16052), although a decent amount of more effort is required. In particular, Sage currently relies a great deal on simple comparison (see the recent discussion https://groups.google.com/forum/#!topic/sage-devel/4Ho98yUmzco), which is no longer supported in Python 3. Some decision will have to be made on how we want to adapt the coercion framework to only rely on rich comparison, and how we want to handle classes that (currently) only support simple comparison. -- Andrew -- You received this message because you are subscribed to the Google Groups "sage-devel" group.

Re: [sage-devel] Build error for sage-6.4.1 in pynac-0.3.2
Not completely sure since the error is about the folder’s group permission but that’s worth a try. I am not sure how the “security” stuff has been implemented, it may be that the group is outside a deemed safe range. Hum, this was implemented here: https://github.com/sagemath/sage/blob/master/build/pkgs/python/patches/sys_path_security.patch#L251 I am guessing in your case the group is writable which of course you want (Fellow HPC admin here). A strategy would be to build in personal directory and then install. François > On 9/01/2015, at 09:26, crooksc...@gmail.com wrote: > > > > O > I am part of the root group.

Is that a bug in sympy?
Note that in the latest git master, we removed mpmath from sympy and
now simply depend on it. So since Sage ships mpmath, sympy would just
use it. Once a new sympy release is made, then one will have to
account for this change (the latest release as of today is 0.7.6 and
that still includes its own mpmath, which maybe clashes with the
mpmath in sage in the above stacktrace?).

That’s interesting, would you belong to an admin group or even the root group?

I tried pip installing the latest version and it breaks everything
(see below). This request should go to sage-devel, by the way.

Note that Clemens Heuberger has started working on proper Sage bindings for Arb (http://trac.sagemath.org/ticket/17194 and sequel tickets). I think this is the right way to go. python-flint is a less serious project, with a more ad-hoc design, mostly intended for my own experiments.

This was a very nice article; sorry I didn't recognize you among your many pseudonyms :) > Today I've got new comment: "I didn't use Sage because I don't see big advantages of Sage in contrast to IPython". I think that is actually just not understanding that Sage and IPython have different (complementary) goals. For many users IPython nb (or its successors) is probably the way to go, but they should still be educated into how Sage will be useful for them (such as that it's easy to use IPython when you already have Sage, but not so much vice-versa). -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
