How to add the yang model to the xml file for Cisco switch version 1741?

Hey guys so I found a python script to add ports to an existing vlan. However, I could not understand how to add the yang models to the xml attribute xmlns? I provided a link to the model on github and tried with and without the '.yang' file type. It just doesn't seem to work.

Any idea on how to include the correct yang model or if the url is wrong?

The code is provided below and so too is the error.

Thank you so much.
