The test code appears to be fine, but the PSNR and SSIM values are indeed strange.
The SeeSR results (PSNR/SSIM, 28.09/0.7664) reported in AddSR are close to those in our paper (PSNR/SSIM, 28.17/0.7691). Can you share your test results?
I found the PSNR/SSIM calculated by the scripts in BasicSR (28.17/0.7674) is correct. But the same images can't get the same results by pyiqa. So, I refer that the PSNR/SSIM in the paper is calculated by BasicSR, and other metrics are calculated by pyiqa.
I use the pre-trained model to predict the SR image of the DReal dataset. Some metrics are different but very close to the data in the paper (error about 0.01-0.1), but the PSNR and SSIM metrics are quite different (26.8475/28.17, 0.7413/0.7691). Here is my metrics calculation method by the pyiqa, can you provide some suggestions?
