I just encountered the same issue. It turns out that Ultralytics couldn't find “WorldModel”. After checking my local version 8.0.3, I promptly upgraded to the latest version, and the issue was resolved.

pip install ultralytics==8.2.70

Don't forget to download efficient_sam_s_cpu.jit or efficient_sam_s_gpu.jit to your local machine.
