I’m using a pretty much vanilla ArchLinux jupyterlab install. I’ve tried all kinds of messing about with configuration of packages but I can never get any widgets to show. The JupyterLab version is 3.4.4.

![20220817_17h25m13s_grim](https://canada1.discourse-cdn.com/flex031/uploads/jupyter/original/2X/1/1843687914e351d5d95e5c4bf75d1c0a506f2cad.png)

Would be grateful for any suggestions.

aplund,  
Assuming everything is installed correctly, I have seen this happen if you installed ipywidgets while having the notebook kernel running.

Have you tried closing jupyterlab completely (not just the browser but the actual kernel), File → Shutdown. Then start it again and see if the issue persists?

Thanks for the reply. Yeah, even a complete system reboot.

I’m not sure if this error is related, but I get it from the browser console each time I evaluate the IntSlider cell:

I am also seeing these kinds of messages in the server logs:

I would suggest that if you don’t hear from anyone with similar experience and a solution here, you might want to open a new issue in [Issues · jupyterlab/jupyterlab · GitHub](https://github.com/jupyterlab/jupyterlab/issues).

It might be unrelated, but there was a very recent release of ipywidgets 8 which might have caused some breakages. In particular, there might be a requirement to have a specific version of `jupyterlab_widgets` with a specific version of `ipywidgets` installed - we saw some problems on JuypterLab CI.

In any case when opening the issue the full information about the installed versions of all jupyter and widget-related packages will be crucial.

Thanks.

Just wanted to say, though, that I managed to get it all working by doing a fresh pip install into a virtualenv. I’ll see if I can figure out the difference between the archlinux packages and what’s in the pip installation.
