This looks like an error in ns-3 - do you get any errors when you call ./waf from your ns-3 installation?
Ok! Just to make sure: if you get the error in SEM, and then immediately go to the ns-3 installation and run python3 waf, it gives no error, right? I'm asking because it might be the case that SEM applies some configurations that you wouldn't normally - this ensures that we are running ns-3 in the exact same way.
If this is still the case, I would like to reproduce this error: can you send a series of commands / code that would allow me to replicate this on my machine?
As for the WNS3 presentation: I don't have the video yet, but it should be published shortly here! You can access the notebook we created during the tutorial by going here: https://magr.in/wns3binder
Attached also series of print screen error for your reference.
It looks like when sending attachments via email they are not included on the github issue - can you post them here from your browser?
Hope this ok?
It looks like your specific error in the attached screenshots has to do with code that is not included in ns-3.31, so it's impossible for me to replicate the issue...
Also, I realized I didn't ask: how did you install SEM? If you haven't done so, a potential solution could be to install the develop branch with the following command:
pip3 install --user https://github.com/signetlabdei/sem/archive/develop.zipClosing for now - let me know if this issue is still bothering you!
