 ### TL;DR
 * The purpose of this folder is to facilitate our CVPR 2024 challenge. Initially, we will use a small subset of training data (**demo train** in the following text) as an illustrative example, demonstrating how to obtain the **test data format** and the submission format, how to train the baseline and infer the baseline, and go through the evaluation pipeline. 
 
-* For the purpose of the new **test data format**, it is essential that our primary intention is to creat a specific test data format preventing possible cheating.
