Name of validation folder for classification training (Export: Folder Structure)

Hi,

when exporting an image classification dataset from Roboflow as Folder Structure format with train/validation splits, the folder which contains validation images is automatically named valid. However, YOLOv5-cls training expects the validation folder to be named val (see here) and throws an error if there is only a valid folder (and no test split). I checked all Roboflow notebooks for classification training and in none of the training procedures a valid folder is actually used for validation.

If the default name for the validation split when exporting a dataset as Folder Structure format would be changed from valid to val, YOLOv5-cls classification training would work as expected, when no test split was created.

Thanks!

Inizia tracciando l’esportatore Folder Structure e confronta la denominazione della directory di validazione con le aspettative di classify/train.py di YOLOv5. Il lavoro è completato quando un’esportazione con split train e validation, ma senza split test, produce una directory val che l’addestramento di classificazione di YOLOv5 può utilizzare.
