您好！
请问为何测试结果不在[0,1]区间？
相同的输入，使用DBCNN, 结果是0.49859，LIQE是3.3864

######Test LIQE#####

import torch
import cv2
import torch.nn.functional as F
import pyiqa

iqa_metric = pyiqa.create_metric("liqe_mix", device="cuda")
img = cv2.imread('/data1/home/Testcodec/bench/jpeg-ai/invcompress/q8/00003_TE_1944x1296.png')
img = torch.tensor(img).permute(2, 0, 1).float()
img = img.unsqueeze(0) / 255.0
print(img.shape)
print(iqa_metric(img))
del img

######Out#####
torch.Size([1, 3, 1296, 1944])
tensor([3.3864], device='cuda:0')
