我正在尝试从以下网站运行一个放大图像的示例：https : //towardsdatascience.com/deep-learning-based-super-resolution-with-opencv-4fd736678066

这是我正在使用的代码：

import cv2
from cv2 import dnn_superres

# Create an SR object
sr = dnn_superres.DnnSuperResImpl_create()

# Read image
image = cv2.imread('butterfly.png')

# Read the desired model
path = "EDSR_x3.pb"
sr.readModel(path)

# Set the desired model and scale to get correct pre- and post-processing
sr.setModel("edsr", 3)

# Upscale the image
result = sr.upsample(image)

# Save the image
cv2.imwrite("./upscaled.png", result)

我已经从网站上下载了已经训练好的模型，名为“EDSR_x3.pb”，当我运行代码时，出现以下错误：

Traceback (most recent call last):
  File "upscale.py", line 2, in <module>
    from cv2 import dnn_superres
