Yolov12 attribute Error

[DolapoSalim]

I tried to run inference on my custom YOLOV12 model but keep running into this error

I have the same problem, have you solved it? 😢

No, I haven’t

[mortvivant]

Could anyone solve it ? I have same problem

[panchaldhruv27223]

!! ALERT ---- URGENT

I ALSO HAVE THE SAME ISSUE.
I HAVE TRIED ALL THE POSSIBLE STEPS TO REOSLVE THIS.
MY MODEL IS LOADING FINE BUT AT THE FINETUNING TIME OR PREDICTION TIME MODEL IS GIVING THIS ERROR.
LAST TIME WHEN I USED IN MARCH MONTH IT IS WORKING FINE BUT NOW MY SCRIPT IS GIVING THIS ERRROR.
CAN ANYONE PLEASED GUIDE ME.

@DolapoSalim, @miftahurrrizki, @mortvivant, @panchaldhruv27223 could any of you update installation command to pip install -q git+https://github.com/sunsmarterjie/yolov12.git@3a336a4adf3683d280e1a50d03fa24bbe7f24a5b and check if that solves the issue?
