I am using a tool called SegmentEveryGrain (). I am a beginner to coding and python and receiving the error "UnboundLocalError: local variable 'all_coords' referenced before assignment when I run the block "Run segmentation on large image (new!)".

I understand that this is telling me that 'all_coords' is being called before it has been defined (I believe?), however I am unsure exactly how to fix this. It seems unlikely to me that this is a problem with the code, and more likely that I have set something up incorrectly.

I am working in a python environment that I set up in the directory that I saved the repo to locally. I have also tried switching interpreters with no luck.

Does anyone have experience with SegmentEveryGrain or a similar situation?

Thanks!

The full code is too long to include here but I have included a link to the github above.
