They still don’t have a semantic segmentation retraining official tutorial/doc like for the object detection and classification but there is a feature request that you can upvote and subscribe:

    Hi, I'm trying to handle semantic segmentation on Edge TPU (w. coral dev board)
…

I found the example model for Pet/Object/Body segmentation [here](https://coral.ai/models/semantic-segmentation/), but I want to retrain the model for my purpose through same approach. (of course I have my datasets that consists on several polygon) 

Is there any place to get retraining code for these purpose?

Thanks in advance.
