Hi I have a project in medical field. I want extract a region of interest in image taken by camera by instance segmentation and CNN technique. I use spyder and open cv and python 3.12 for a long time and I am ease with these. I have about 100 images collected as datasets for training model(Image as dataset is shown below). But there is a fews problem. One of them is that I am not expert in CNN and am amateur in image processing. I use first mask rcnn then find that is not compatible with python 3.12 and got in wrong. Second use yolo5 and got the error of cach may be out of date.so i try change my route in this project and from starting learn a simple model of learning by a simple task of instance segmentation just extract a circle in many objects. So love one that help me to do that with spyder 3.12 and open cv and tensorflow and keras. Also regard me that i am not very expert in CNN.

I try to use u net and yolo 5 but is over knowledge of me. They are not compatible with my libraries.
