Just create a Dataset for that. Something like
class MyDataset(torch.utils.data.Dataset):
    def __init__(self, list_of_images, list_of_labels):
        self.list_of_images = list_of_images
        self.list_of_labels = list_of_labels
        assert len(list_of_images) == len(list_of_labels)

    def __getitem__(self, idx):
        return self.list_of_images[idx], self.list_of_labels[idx]

    def __len__(self):
        return len(self.list_of_labels)
