Tfrecords Guide

A post showing how to convert your dataset to .tfrecords In this post we will cover how to convert a dataset into .tfrecord Binary files are sometimes easier to use, because you don't have to specify different directories for images and groundtruth annotations. While storing your data in binary file, you have your data in one block of memory, compared to storing each image and annotation separately. Openning a file is a considerably time-consuming operation especially if you use hdd and not ssd, because it involves moving the disk reader head and that takes quite some time. Overall, by using binary files you make it easier to distribute and make the data better aligned for efficient reading.
