No segmentation seen with pyvista

I was following instructions on the website. However, when I get to the " Getting Started with Segmentations", I failed to visualize the segmentation with pyvista as demonstrated by the instructions.

Is there anything I missed? Thanks!

Do the previous steps appear to have worked?

Yes, they seem to work without problems.

Can you upgrading pyvista?

conda activate shapeworks
pip install pyvista==0.43.4

This worked for me.

If you look super close, the the segmentation is there, but it looks like a smudge.
