How to generate prediction of instance segmentation without bounding box, class, edge and probability?

[aihcyllop]

When I finish training for instance segmentation and use demo.py to generate masks, I get the result of the first image.

First image includes box and class(0 in this case) and probability.

Also, the segment object has edge with different colors.

I want to ask how to generate the mask like the second image.

I want to generate image without edge, box, probability and class.

Hope someone can help and thank you so much.
