Hi,
To resolve the issue you are facing, it is usually a case in the training step..
Try and change the LR (learning rate) and adjust your training process and check if it fixes the issue.
Thank you

Well, Thanks. Maybe this issue was caused by so large of my picture. The learning rate was followed with the default in the mask2former source paper.

Hi,
Glad you found it useful! :)
Try adjusting parameters related to image resolution, batch size, augmentation techniques, or even model architecture to fine-tune your instance segmentation setup.
If you need further guidance or have specific questions, feel free to ask!
