Javascript error box appears instead of an image

[slavistan]

Hi! I'm trying to produce a few simple bounding boxes for a set of images. Unfortunately, I run into the following error using the basic example from the project readme:

Clicking the box expands the following message:

I'm trying to run jupyter-innotater inside Jupyter Lab, having installed it via conda install -c conda-forge jupyter_innotater.

Here's the output of jupyter --version, just in case. If more input is helpful to debug this issue, please let me know.

Thank you for this. I think the problem is with ipywidgets 8.0. Innotater needs to undergo a migration to support that, as described here: https://ipywidgets.readthedocs.io/en/stable/migration_guides.html

I don't have any time or funding to do this myself right now. I would be very happy to accept a Pull Request if anyone wants to take a look.

I would support a PR that simply works with ipywidgets 8.0+ without backwards compatibility.

I hope this helps explain the problem at least... In the meantime, it should be possible to get Innotater (and many other widgets!) to work with slightly older versions of your setup, in particular ipywidgets 7.
