Expected Behavior

Plugin widget should appear in the napari GUI

Reproduction

Please list the exact steps we can take to reproduce this bug.

  1. Click on Plugin > napari-allencell-segmenter > workflow editor (or batch processing)
  2. Error message notification popped up in UI
  3. No plugin windows opened

Environment

Operating system (ex. MacOS Big Sur): MacOs Catalina Python version (ex. 3.8): 2.7.16 How did you install the napari viewer (as a bundled app or through command line with pip)?: Bundled App

schoinh commented 2 years ago

I wonder if this is because we don't support Python 2?

schoinh commented 2 years ago

@lynwilhelm Which version of napari did you install? (Sorry, I need to add this to the bug report template.) This page is confusing because it tags v0.4.12 as the latest but also says that a version released in Nov 2020 (nightly build) is also "latest."

You should be able to check the version by going to Help -> napari info in napari.

I was able to reproduce this bug after installing napari (v0.4.12) through the bundled app download. I was not able to reproduce this bug after installing napari (v0.4.12) via pip.

Found a similar error in this old (closed) issue on the napari repo, maybe related to magicgui: https://github.com/napari/napari/issues/2733
