Hi, There are currently only half a dozen standard orders, and a product order for the construction some non-standard orders. However, I believe that it should not be hard to define a new subclass of MonomialOrder (say, WeightOrder) that would accept weights for different symbols (as a dict,

Right, the test time is likely to be affected further on the account of lesser concurrent builds on Azure. -- You received this message because you are subscribed to the Google Groups "sympy" group. To unsubscribe from this group and stop receiving emails from it, send an email to

This is a very odd bug. I bisected it to this SymPy commit, which doesn't seem to have anything to do with the issue commit dad0f6890e752faf2f622891458de83401a91a12 Author: Raoul Date: Thu Jan 11 04:18:39 2018 +0100 Add the tribonacci sequence Aaron Meurer On Thu, Nov 8, 2018 at 1:36 PM

You should be able to define your own order class (see sympy/polys/orderings.py), and pass it as the order argument to those functions. Aaron Meurer On Thu, Nov 8, 2018 at 1:15 PM wrote: > > I would like to define a polynomial term order using a weight vector (other > than the lex, grlex, etc).

To be fair, the runtimes aren't exactly comparable because they currently run different things. Azure runs 3.7 whereas Travis doesn't, and Azure still needs to run the slow tests, docs build, and PyPy tests. Regarding the optional dependency build, it is currently failing because of some broken

Hello, My name is Sara and I'm a post-doc in the Applied Mathematics department at IIT (in Chicago). One of my thesis projects, I tinkered quite a bit with Sympy before developing a package for Macaulay2. I'm interested in making an analogous package in Sympy; however, to do so, I need to be

I would like to define a polynomial term order using a weight vector (other than the lex, grlex, etc). I have looked through the documentation, but do not see any way to do this. Is this possible with sympy? The functions I am using are things like LM and LT. -- You received this message

To start with I cannot give a simple example using only sympy. I have only been able to generate this failure using my modules. Below is code and output showing as simple an example as I can generate with some diagnostics. If you could suggest any other diagnostics I would appreciate it.

Nice, the tests seem to run faster on Azure on individual jobs compared to Travis. Although, the overall testing time seems to be comparable for both. https://dev.azure.com/SymPy/SymPy/_build/results?buildId=266=logs

I think the repos which include sympy as a requirement in setup.py (or have done it in the past, visible in git history) are listed as packages. Packages on PyPI are not necessarily listed as dependent packages. (The first listed repo https://github.com/abinit/abipy being an example) On
