有没有办法用python检查一张图片占用了多少内存？

import sys
from PIL import Image

def get_image_memory_usage(image_path):
    image = Image.open(image_path)
    image_size = image.size[0] * image.size[1] * image.info['bits']
    image_memory_usage = image_size / 8 / 1024 / 1024  # 转换为MB
    return image_memory_usage

image_path = 'path/to/your/image.jpg'
memory_usage = get_image_memory_usage(image_path)
print(f"The image occupies {memory_usage} MB of memory.")
