Cant import Viewer

[gattia]

Seems to be the same problem as https://github.com/InsightSoftwareConsortium/itkwidgets/issues/615 However, updating to the latest alpha just produces other errors:

I tried reverting back to an old itkwidgets (0.32.5) and that failed too. I had github actions running tests 2 weeks ago that are now failing.

2 weeks ago: https://github.com/gattia/pyfocusr/actions/runs/4152699476/jobs/7183836252 Today: https://github.com/gattia/pyfocusr/actions/runs/4267422214/jobs/7429010153

Looks like ipydatawidgets released a new version last week and it has broken something in the itkwidgets pipeline... https://pypi.org/project/ipydatawidgets/#history

if install ipywidgets<4.3.3 things work. I will report to ipywidgets too.

@gattia thanks for the information! If ipydatawidgets is downgraded to 4.3.2, does the issue still occur?

[gattia]

Yep, 4.3.2 works as expected.

Happy to close if this is considered a problem with ipydatawidgets. But might be good to change requirements to <4.3.3 at least for now.

@gattia :+1: adding constraint in #624.

Pin released in 0.32.6
