You must seperately install `ipywidgets` for things to work fully in a IPython 3 backward compatible way.\r\n\r\nMy suggestion to Continuum was to include `ipywidgets` as a hard dependency of `ipython-notebook` 4. They said this was an upstream issue. It may also affect `pip install ipython[notebook]` but I haven't checked."}}
