Yolov4 custom : split modification

[pidoux7]

Hello,
I am working on customizing YOLOv4, but I have encountered an issue.
Some of my images are not independent and must be grouped together in either the training or testing set. In order to address this, I would like to modify the 'split_data' function in data.c.
However, I am unable to determine which images should be grouped together without accessing their file paths, but I am unsure where to locate this information in the code. Additionally, I am curious as to how the images are associated with their respective filenames.
Thank you very much for your answer.
