Just compiled sage from source code on Linux.
When I launched ./sage, I can do simple math like 2+2 which give correct

Hi Kwankyu,
The _test_category issue is something that shows up with every map (and
I think homset). This is because the parent (i.e., the homset) does not
(usually) have a single Element class, but the _test_category is checking
that the map is a subclass of the element_class that is
I've opened

to deal with this issue.

Unfortunately, this is not a good idea.
We are working hard on making Sagemath compatible with Python 3.
With Python 3 you cannot sort objects of different types. For instance
sorted([1, 'a']) will raise an error.
Currently, in the graph module, vertices can be any hashable objects, so we
try
Thanks for the fix! I have a suggestion, though:
You changed "nodes" to go over the vertices in the order determined by the
hashmap.
I'd suggest to change "v_to_id" to go over the sorted vertices instead,
i.e. something on the line of:
V = G.vertices(sort=True)
v_to_id = {v: i for i, v in
My bash version:
GNU bash, version 4.3.0(1)-release (x86_64-unknown-linux-gnu)
The reason I want to install from source as to use on my linux box
I am not sure what you meant by "a clean docker container".
Anyway, I have managed to overcome some problems after last mail. Still
working on it...

Hi,
I thought the idiom to define a map is:
from sage.categories.map import Map
from sage.categories.homset import Hom
from sage.categories.fields import Fields
class Derivation(Map):
def __init__(self, field):
Map.__init__(self, Hom(field, field, Fields()))
But then the last two

Given a (di)graph, you can easily assign random edge weights using for
instance `G.set_edge_lable(u, v, randint(1, 100))`.

This means that there was an error building openblas Sage package.
Have a look in logs/pkgs/openblas.log
Do you see an error there?
