+**NOTE**: These installation instructions install `ipywidgets` version 7.7. We anticipate that ipywidgets 8 will be released before the tutorial. If it, and all of the packages that we use that are dependent on `ipywidgets` have releases before the tutorial we will also provide ipywidgets 8 installation instructions.
