by the `image_std` parameter in the `preprocess`
                method. Can be overridden by the `image_std` parameter in the `preprocess` method.
            transform (`Callable`, *optional*, defaults to `None`):
                A custom transform function that accepts a single image can be passed for training. For example,
                `torchvision.Compose` can be used to compose multiple transforms. If `None` - an inference mode is
                assumed - and then a preset of inference-specific transforms will be applied to the images

        Returns:
            a PyTorch tensor of the processed images
