Hello! I am trying to use SegmentWithSAM module. I downloaded it through Extension Wizard, restarted Slicer a few times, and the module has no prompts or buttons on the left hand side of the screen. I looked at the error code and it mentions something about a bad git. I am not quite sure what that means or if that is the problem. Does anyone have any ideas on what to do?

Here is a photo of the interface:

I haven’t seen any SAM variant outperforming classic interactive segmentation tools for medical image segmentation. Therefore, I would not spend time with trying to figure out why this this extension fails.

In contrast, NNInteractive model is an AI-based interactive segmentation tool that actually works, and it works really well. For many segmentation tasks it performs much better than classic tools. You can often get a perfect segmentation of a bone from a single click. I would recommend to use it instead of any SAM-based tools. It is available in the Extensions Manager.

The NNInteractive model needs a Nvidia GPU which we do not have yet. I will try NNInteractive once we have a Nvidia GPU. Thank you for your help.

You can always give it a try on [MorphoCloud]([https://morphocloud.org](https://morphocloud.org)). Brief instructions are here:
