Version incompatibility

[akhmerov]

Describe the issue

I seem to observe the incompatibiltiy similar to one previously reported in #161: widget model not found and JS console with an error. This is using the latest versions of everything as far as I can tell.

Uncaught (in promise) Error: Module jupyter-matplotlib, semver range ^0.11 is not registered as a widget module

Thanks for opening an issue. Do you see another error in the JS console prior to the semver range ^0.11 is not registered one?

[akhmerov]

Ah, you're right! I see

[martinRenou]

Do you see core widgets working?

from ipywidgets import IntSlider
IntSlider()

[akhmerov]

Indeed, I did confirm that.

[martinRenou]

Mmmh I cannot reproduce your issue with ipywidgets=7.7.2 and ipympl=0.9.2, I also confirmed that I have the same labextension versions for jupyter-matplotlib and @jupyter-widgets/jupyterlab-manager, which is the minimum for ipympl to work.

I suspect one other installed labextension is breaking things up. Could you recreating your environment with less extensions to try to spot the culprit?

[Irratzo]

I can reproduce the "Error displaying widget: model not found" issue with ipywidgets=7.7.2 and ipympl=0.9.2. I also confirmed that I have the same labextension versions for jupyter-matplotlib and @jupyter-widgets/jupyterlab-manager.

Core widgets are working.

Might downgrading ipywidgets be a solution?
