@nicolaskruchten or anyone
FYI, I experienced the same issue with branchtotals in the context of dash (not a jupyter notebook). From another post (📣 Plotly.js 2.0 is coming soon!) it looks like plotly.js comes with dash-core-components
I conda upgraded both, but both seem to not work for me. I also upgraded the jupyter stuff on the getting-started page for the heck of it.
To others, i ended up using remainded and parents=0 workaround
