Output file when training detectnet 2

After training this file gets saved into the respective directory:


What events does this folder contain and how can I extract the information from it?

This event file records some summary data.
Reference: https://github.com/tensorflow/tensorboard/blob/master/README.md

Can I use that file and use it with tensorboard outside of tlt and do it my own?
