using --plot-dir argument leads to distutils.errors.DistutilsInternalError: about topology HOT 5 CLOSED

Our assumption was that nobody was using that functionality, do you still want topology to support --plot-dir?

It's hilarious :) no, just drop it, i'll generate custom .dot file regarding my L1 network model.

Good luck!

nevermind, looks like it already fixed in master branch, i will close this issue

Hi @metacoma, Did you notice that the master version does nothing (I mean, no longer makes the actual plot)?

Are you actually using the topology plots it generates? We thought that most people had the --plot-dir in the command but did not actually use the generated plot, so that is why we left it with no implementation as backwards compatibility temporary measure.

@sergiosmcr hello

Did you notice that the master version does nothing

Yep, i read it in changelog. So, I using version from pip

topology==1.17.0

I fixed the bug (it was just a typo in variable name) and then it worked
my topology looks like

topology --plot-dir ... generated the following image

Are you actually using the topology plots it generates?

Well, i need to visualize L1 network layer of my home cluster and was looking for the tool that can do this.

BTW, is there a way to somehow visualize .nml file ? I googled a bit, but didn't find anything :(

Thank you for your time!

We used to rely on ExtendedNMLManager.save_graphviz() to generate the plot depending on the format.You probably are using the default svg format. That function generates a graphviz file, then uses graphviz dot executable to convert the file to svg, png or any other format.

The way we used that API can be found here:

Maybe you can try to implement it in a PR? 🙂 The problem is that now we don't use NML, so implementing it is not that easy.
