TypeError when attempting to view a buffered subimage with itkwidgets==1.0a35

[tbirdso]

Overview

Observed an error when attempting to view an itk.Image with itkwidgets==1.0a35.

I am not 100% certain that the error lies in itkwidgets. The stack trace includes ngff_zarr, dask_image, and scipy.

@tbirdso thanks for the report!

Looks likely to be a dask-image / scipy issue. For reference, could you please add:

• Python version
• dask-image version
• scipy version

?

Looks likely to be a dask-image / scipy issue. For reference, could you please add:

Sure thing, I've added this information to the issue summary. My dask-image version looks old, will attempt to reproduce with the most recent version.

EDIT: I am able to reproduce with the latest version of dask-image. I have updated the issue summary accordingly.
