Creating a validation set with ImageDataBunch

Hi everyone, a deep learning newbie here. I watched the first video and wanted to train a Devanagari script dataset. I have 45 different classes(36 letters and 9 digits) from the Devnagari script in the training set and the same number of classes in the test set. Now, I want to create a validation set from the training set. When I use ImageDataBunch.from_folder(path, train = trainpath and valid_pct = 0.2) does it create a validation set by itself with images from all the data classes in it? Or do I have to do it manually? Also, is there anyway I can see the created train/validation set to verify the classes and images in them?

Thank you in advance. :slight_smile:
