How to make sure all classes are in test and validation sets

Hello, is there any way to ensure that all classes are within the test and validation sets? I am working on a dataset here and I discovered that only one class is present within the test and validation sets. Thank you

Hi @roguewindrunner, you can filter down to images by class, and then change the sets that way: Health Check: Filter by Class - Roboflow

Or, you can choose “Split Images Between Train/Valid/Test” after selecting “Finish Uploading,” and be sure you are uploading an image set that contains multiple representations of all classes, as the split assignment is randomized by the train/valid/test split you enter.
