What should be there in VAL_JSON_FILE?

[sayakpaul]

Hi folks. It's been a while that I am using the TensorFlow Object Detection API and I absolutely love using it. But I have been using it with a TensorFlow 1.13.1 backend and I was really happy to see the development direction going forward with supporting TensorFlow 2.x backend as well.

Because of the fact that TFOD API works based on declarative configurations, I think mentioning what should be there in VAL_JSON_FILE would be helpful. As far as I know, the TFRecords that we are supplying already contains the annotations of the bounding boxes, so in that case what exactly should be there in VAL_JSON_FILE and in what format?

Thanks in advance for your time.
