There’s a couple of options to help you.
The easiest one is using Model Maker. This is not for on-device only! You can train regular TF models with it too.
On Model garden, you can follow these tutorials here: models/research/object_detection/colab_tutorials at master · tensorflow/models · GitHub 1
more specifically the Eager few shot training
Some more info here:
