In this repository I replicated the pipeline for use the Object Detection API. You can find here: Training Custom Object Detector
I've used a custom dataset which was made the annotation using the labelImg. More explanation in the jupyter notebook
After running: python object_detection/builders/model_builder_tf2_test.py I got this:
ImportError: cannot import name 'builder' from 'google.protobuf.internal' (/home/brenoav/anaconda3/envs/od-api/lib/python3.8/site-packages/google/protobuf/internal/__init__.py)
