itkwidgets installation missing compare

[tenres]

I get the below error when trying to import compare. I would like to use it with ITKElastix.

from itkwidgets import compare, checkerboard, view Traceback (most recent call last): File "", line 1, in ImportError: cannot import name 'compare' from 'itkwidgets' (anaconda3/envs/itk_elastix/lib/python3.8/site-packages/itkwidgets/init.py)

I used the following command for installation: pip install 'itkwidgets[all]>=1.0a23'

Thanks!
