Hello @mjasner ,
Sorry, this problem maybe occur in convert tool. Our engineer still find the reason.
Actually, the problem have encountered before.
Unable to convert yolov8n to .nb - VIM3 - Khadas Community
The solution way is using the same Ultralytics and PyTorch version with our demo.
But this version do not have YOLOv11.
I will notice you inform you at once when we solve the problem.
