i am having the same issue

[Norticaranda]

I am too Any track? Thanks

as per my comment in the other open issue (https://github.com/Azure/Azure-TDSP-Utilities/issues/38):

so it looks like all you need to do is downgrade ipywidgets to 4: i did the following:

pip uninstall ipywidgets
pip install ipywidgets==4

and it worked I would highly recommend the team developing this tooling to provide a conda dependencies yml file to ensure environment is created with all the right dependencies

[jreynolds01]

I've just created a pull request to add a conda environment yml file to address this.
