[sage-devel] Re: py3: issue with round

[Frédéric Chapoton]

You could add (at the price of some speed)

from sage.misc.functional import round

[sage-devel] py3: issue with round

[David Coudert]

Does anyone know a suitable way to fix the following issue with round in 
Python3 ?

sage: G = Graph([(0, 1)])
sage: f = g._build_flow_graph({(0, 1): 1}, True)
---
TypeError Traceback (most recent call last)
 in ()
> 1 f = g._build_flow_graph({(Integer(0), Integer(1)): Integer(1)}, 
True)

/Users/dcoudert/sage3/sage/local/lib/python3.6/site-packages/sage/graphs/generic_graph.py
 
in _build_flow_graph(self, flow, integer)
   9094 g.delete_edge(u, v)
   9095 else:
-> 9096 g.set_edge_label(u, v, int(round(l)))
   9097 
   9098 # returning a graph with the same embedding, the 
corresponding name, etc ...

[sage-devel] Re: python3 status report

[Volker Braun]

Also, I have now set up a Python3 buildbot to catch regressions!

[sage-devel] Re: Help wanted to diagnose a system-dependent bug : R lost its graphics abilities

[Emmanuel Charpentier]

Never mind... The problem turned out  to be that out freetype library was a 
bit too outdated for R. This is now fixed in a positive-review ticket 
.

[sage-devel] Re: spkgs dependencies graph

[Volker Braun]

If you want to use it for external dependencies you'll probably need to 
know about acceptable versions of these. Then you'll soon need a sat 
solver; E.g. conda does in that way.
