AttributeError: 'Curve' object has no attribute 'smooth'

Hi!
I am getting this error while running the codes for Sonic & Density Smoothing.
Please resolve this asap. I have updated all the dependent packages but it's still not working.
Thank You!

did you ever get this working?
Lot's of people post code that doesn't work, as a lead for 'consulting gigs', this is quite common on github;

the smooth problem isn't important, and the work around for 'welly' is to import locally, but the pandas problem in w.df() is a major show stopper, because without a data-fetch method you have nothing
