Comment:
Hello,
The patchbot reports compilation errors associated with ticket #18746. I
don't know why...
Actually I have the same issue when I try to compile my develop branch,
and so I'm currently unable to test this patch.
Concerning this ticket. Don't feel guilty to steal networkx. It is very
useful and we will certainly also have to do the same for reading graphs
from file.
I suggest to change the way you guess the file format with something like:
{{{
for ext in formats:
if filename.endswith('.'+ext):
break
finally:
raise ...
}}}
With networkx it is possible to give extension like `.edgelist.gz` in
which case the file should be compressed (at least with version 1.9.1, but
we only have 1.8.1). See
https://networkx.github.io/documentation/latest/reference/generated/networkx.readwrite.edgelist.write_edgelist.html
David.
