ValueError in Run segmentation （attempt to get argmax of an empty sequence）

[h-m-088]

Nice to meet you. Thanks for such a great model.

I am trying to run Segment_every_grain.ipynb on VScode.

I rewrote part of the contents of the distributed Segment_every_grain.ipynb (see attached photo), and when I ran it, I got a "ValueError: attempt to get argmax of an empty sequence sequence" in "Run segmentation".

I would like to know the solution.

*I am using Google Translate.

Environment
・Mac book pro14 (M1pro)
・VScode(anaconda)
・Python(3.12.2)
・library list (see attached photo)
