ipaddlepaddle2.2.2代码 paddle.fluid.*已经被 paddle.*取代

是的，您说得对，非常感谢您的提醒。下面是更新后的代码：

import paddle
import inverse_isp_paddle as inverse_isp
import os
import glob
from PIL import Image
import numpy as np

os.environ["CUDA_VISIBLE_DEVICES"] = '0'

def read_jpg(filename):
    """Read an 8-bit JPG file from disk and normalize to [0, 1]."""
    image_file = paddle.static.io.file_reader(filename)
    image = paddle.vision.transforms.image_decode(image_file, 'jpeg')
    return paddle.cast(image, 'float32') / 255.0

def read_img(filename):
    """Read an image in most formats."""
    image_file = paddle.static.io.file_reader(filename)
    image = paddle.vision.transforms.image_decode(image_file, 'auto')
    return paddle.cast(image, 'float32') / 255.0

def convert_to_raw(image):
    """Unprocess sRGB to packed raw."""
    assert image.shape.is_compatible_with([None, None, 3])
    image, metadata = inverse_isp.unprocess(image)
    return image, metadata
