        size (`Dict[str, int]` *optional*, defaults to `{"shortest_edge": 224}`):
            Size of the image after resizing. The shortest edge of the image is resized to size["shortest_edge"], with

        image_mean (`float` or `List[float]`, *optional*, defaults to `OPENAI_CLIP_MEAN`):
            Mean to use if normalizing the image. This is a float or list of floats the length of the number of
