Package: python-networkx
Version: 1.7~rc1-3
Severity: normal
Dear Maintainer,
networkx raises TypeError when reading input from .gml file:
$ python cart_product.py c3.gml c3.gml
graph [
node [
id 0
Traceback (most recent call last):
File "cart_product.py", line 22, in <module>
for line in nx.generate_gml(X):
File "/usr/lib/pymodules/python2.7/networkx/readwrite/gml.py", line 328, in
generate_gml
yield 2*indent+'label %s'%label
TypeError: not all arguments converted during string formatting
Bug is affecting Debian stable and sid. It seems that version 1.7-2 in
Debian experimental contains the same bug, since it contains the same
line in file gml.py.
It seems that bug is fixed by applying the following patch (tested for
debian stable and sid):
--- a/networkx/readwrite/gml.py
+++ b/networkx/readwrite/gml.py
