Preparing data for fine-tuning (segmentation)

[MariaKalt]

Hello,
I want to use your implementation to fine-tune for segmentation on my own data.

Can you tell me how to prepare my dataset? How can the needed labels best be produced?
If I understand correctly, your implementation fine-tunes for segmentation not instance-segmentation, right?

I would be very glad about any help you can give me to get started on the training.
