Hello!  
I have been getting this message when I load the 3d slicer and I wanted to know if this is something I should be worried about.  
I thought this was a default message, but as I go through the forum I have been realizing this is should not happen…  
As a python beginner, I don’t fully understand the message.  
Can someone please help me to understand what this means and what kind of action I should take?  
From what I could understand, the only parts with problems are print command?  
If so, is this something I should not be worried about?  
Thank you always for your help.  
Greatly appreciated.

That extension hasn’t been updated to work with current Slicer. You may be able to use it with an older release.

Watershed segmentation is now available in [Segment Editor in `Watershed` effect](https://github.com/lassoan/SlicerSegmentEditorExtraEffects/#watershed). It is provided by SegmentEditorExtraEffects extension. For many cases `Grow from seeds` effect work better, so I would recommend to try that, too.
