Dataset Preparation Guide

If you want to use prepared configs to run the Accuracy Checker tool and the Model Quantizer, you need to organize <DATASET_DIR> folder with validation datasets in a certain way. Instructions for preparing validation data are described in this document.

Each dataset description consists of the following sections:

• instruction for downloading the dataset

• structure of <DATASET_DIR> that matches the dataset definition in the existing global configuration file (<omz_dir>/data/dataset_definitions.yml)

• examples of using and presenting the dataset in the global configuration file

More detailed information about using predefined configuration files you can find here.
