My question is how/where to find guidance for implementing Semantic Segmentation on our own data.  
First, how to label a training set for Semantic Segmentation. How does a “trainer” generate the masks? I realize that labels should be generated for every pixel. Seems daunting; I am sure there are efficient tf/Keras ways to do that…  
Thanks for your help

Hey @EduardoChicago,  
I believe that applying semantic segmentation on existing datasets is out of the picture, but if that is something you want to consider, you can check this [thread](https://community.deeplearning.ai/t/any-recommendations-for-semantic-segmentation-dataset/154194) out.

Now, coming to your exact question, [this](https://community.deeplearning.ai/t/week3-how-to-prepare-the-ground-truth-vector-y/136414) and [this](https://community.deeplearning.ai/t/c4w3-data-annotation-for-semantic-segementation/106020) thread discusses how to prepare the ground truth vectors for images in your own dataset.

Let us know if this helps.

Cheers,  
Elemento
