@Cristian_Lorenzin, yes we haven’t made a official tutorial to retain a semantic segmentation model.Just because the procedure has been changing with new models. But we will consider your feedback to make one.
I mean time you can try steps below to retrain a model for edgetpu
follow steps here to train and export 6 a model.
refer here for checkpoints ( I have tried mobilenetv2, mobilenet-edgetpu) feel free to try other backbones as shown on coral.ai/models
The trick is to get quantization right.
Though you have trained and exported model in TF1.x you should use PTQ in TF2.x > 2.3 to quantise the model. Finally use edgetpu compiler to compile the model.
Let us know you have any questions.
Thanks
