aics-imageio fails to open .tif files

[thawn]

Hi,
thank you so much for providing this great reader plugin for napari. It has helped me a lot!

However, in the recent version, when I try to open .tif files, I get the following error message in napari:

ValueError: Plugin 'aicsimageio-in-memory' was selected to open ['Z:/Till/188_viventis_data/downscaled_mCherry.tif'], but returned no data.

steps to reproduce (on Windows 11 with mambaforge):

mamba create -n minimal-example napari-aicsimageio
mamba activate minimal-example
napari

in napari go to file->open and select a tif file and choose aicsimageio as reader plugin (example.zip contains file that I used for testing)

mamba list output

I think this might be the same as:
napari/napari#5837
Not sure though because of the npe vs npe2 bit.
But maybe you can try downgrading npe2 to npe2==0.6.2

@psobolewskiPhD thanks a lot for the tipp.

Activating "Use npe2 adaptor" in Preferences->Plugins as suggested by @DragaDoncila fixed the issue for me.

However, activating the npe2 adaptor broke the tools menu. Hence I decided to downgrade npe2 to v0.6.2 after all.

Maybe this could find its way into the readme under installation?

I think this will all be fixed with the 0.4.18 release, which is ComingSoonTM (no seriously, we're working on it!)

sounds great, looking forward 😄
