The IntSlider widget works in NbClassic, but not in JupyerLab & Notebook. Same goes for other widgets. Reproducible: Always Steps to Reproduce: 1. Start jupyter, e.g.: ```sh jupyter notebook --notebook-dir=/tmp/N --NotebookNotary.db_file=':memory:' --PasswordIdentityProvider.hashed_password='sha1:320c57170183:31d7aff2b7f1990b1869b82e83934e5185cebf97' --ServerApp.allow_remote_access=True --ip='127.0.0.1' --no-browser ``` 2. Open http://127.0.0.1:8888/ in Firefox and login with password `123456` 3. Create and run a notebook with this code: ```python import ipywidgets as widgets from IPython.display import display w = widgets.IntSlider() display(w) ``` Actual Results: Just this plain text: > IntSlider(value=0) Expected Results: An integer slider widget like described in the [documentation][1]. [1]: https://ipywidgets.readthedocs.io/en/stable/examples/Widget%20Basics.html#display I think that the jupyterlab_widgets dependency is missing. The latest Anaconda Python distribution works fine.

You are right. Thank you for the report. I've prepared a new package that should bring the missing functionalities to Jupyter lab.
The new package will now undergo a review but if you don't want to wait or if you want to help with testing, you can install it from https://copr.fedorainfracloud.org/coprs/lbalhar/python-jupyterlab-widgets/
I've installed it to do a quick test and it seems to be working.

Shouldn't python3-ipywidgets updated as well to depend on python-jupyterlab-widgets ?
Yes, I plan to do that, see: https://src.fedoraproject.org/rpms/python-ipywidgets/pull-request/22 https://src.fedoraproject.org/rpms/python-ipywidgets/pull-request/23 https://src.fedoraproject.org/rpms/python-ipywidgets/pull-request/24
