What is the YOLO Keras TXT Annotation Format?

Overview

This annotation format consists of two files: a text file containing all the annotations and a labelmap file mapping the integer class IDs to their human-readable names.

But you don't really need to worry about the details because Roboflow can both import and export this format!
