So is Sage following those instructions during its build process? The docs do not say what those jupyter commands actually do. They have separate instructions for enabling the widgets when using a virtualenv. Of course Sage's venv is not a true virtualenv as created by venv, so it is hard to know whether the virtualenv instruction apply for Sage or not. But given that the widgets worked before Sage switched to its virtualenv-like venv I would guess that they do apply.
It is unclear to me whether this is an issue with the packaging of the SageMath app for macOS or whether it is an issue with Sage's build process, which I follow when building Sage for the app. It would be helpful to know the meaning of the sentence "Most of the time, installing ipywidgets automatically configures Jupyter Notebook to use widgets." Specifically, what does it mean to "configure Jupyter Notebook to use widgets". - Marc On Tuesday, February 1, 2022 at 1:26:33 PM UTC-6 slelievre wrote: > 2022-02-01 15:13:27 UTC, Marc Culler: > > > > Thanks.
