Hi there!
Due to certain limitations, we are trying to install the graphtool version 2.7 on a redhat distribution.
After a lot of fidling around, we have been able to make the functions we need work, except for the find_edge_range function.
The following simple example demonstrates the problem:
from graph_tool.all import *
g = Graph()
v1, v2 = g.add_vertex(), g.add_vertex()
e1,e2 = g.add_edge(v1,v2), g.add_edge(v2,v1)
res = g.new_edge_property("double")
res[e1] = 0.1
res[e2] = 12.
eList = find_edge_range(g,res, [0.0, 1.])
This causes the following issue:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/graph_tool/util/__init__.py", line 84, in find_edge_range
convert = converter(prop.value_type())
NameError: global name 'converter' is not defined
Unfortunately, I have not found a way to see the actual code, where this error arises.
Was this a problem in that particular version?
What do I need to do to find the code where this issue arises?
The following python loop is able to reproduce the desired behavior, but it is way too slow:
eList = []
for e in g.edges():
if res[e] <= eps and res[e] >= 0.0:
eList.append(e)
Is there a more efficient way to do this, if I cannot make "find_edge_range" work?
Looking forward to hearing from you.
All the best,
Alex
