"thread '<unnamed>' panicked at /herro/herro/src/mm2.rs:37:10" running demo sequence

[runujhkj]

Hi, I don't have the best understanding of what this software is doing, I'm just an admin. I got it compiled via Rust, I think, and followed the environment setup (LIBTORCH and LD_LIBRARY_PATH), but running the demo sequence given in the github repo at demo/README causes a panic and fails:

I'm still looking into what's going on, as I'm assuming the issue is with my own lack of knowledge on herro, Rust, every part of this really. Figured I'd post it here as well.
