Hi, @Caliphamin 👋🏻! Could you share a link to the dataset you used?
@SkalskiP sure https://app.roboflow.com/wall-9lypi/wall-floor-k0mnz/7
Hi, @Caliphamin 👋🏻! I examined the issue. And I think I know the reason.
Roboflow allows you to use bounding boxes in segmentation projects. However YOLOv8 project does not allow for such flexibility. Because your image segmentation dataset contains boxes, it fails to load correctly. But... I tried to use your dataset for object detection training with this command:
!yolo task=segment mode=train model=yolov8s.pt data={dataset.location}/data.yaml epochs=3 imgsz=640
And it works. :tada: I know it is not e perfect solution, but given the current situation, I think it is best we can do it quickly.
I'm closing that issue. Feel free to reopen it if needed.

Bug
hello i want to instance segmentation with yolov8 but i've got this error and i am stuck here i use this command to run yolov8 !yolo task=segment mode=train model=yolov8m-seg.pt data={dataset.location}/data.yaml epochs=100 imgsz=1024 batch=8 my images width and height are 1024x1024 i get this error
Sizes of tensors must match except in dimension 1. Expected size 57 but got size 0 for tensor number 1 in the list. Sentry is attempting to send 1 pending error messages
also when i change image sizes or batch size the number of expected size changed in error
Environment
