It looks like you have an older version of ipywidgets that doesn’t need the widgetsnbextension package. The widgetsnbextension package is needed in ipywidgets 5.0 or later. It also looks like conda does not yet have ipywidgets 5.x available.

What is your end goal here? If you just want to use widgets, the older version that you have installed and is available through conda should just work.
