i test some low light images with the pretrained model, and the result seems not good. did I make an error? #5

same here. I try to test on LOL dataset with images 690-789 as described in the paper. However, I was only able to get PSNR of 9.687. The number stated in the paper is 20.13 (Table 1). Is there anyone else have a similar problem?

@flyywh Is it possible that the weight you uploaded for model_R_s2.pt is corrupted? it is only 78kb

Hi, I also meet the same problem. I got PSNR of 11.824. Have you solved the problem? Thanks a lot.

  1. First, 20.13 (Table 1) is achieved by the first stage. More details can be seen in the first point of Detailed Guidance.
  2. Such low PSNRs are obtained as stage 2's PSNR calculation in stage2-other-datasets (stage2 in the original version) are meaningless as the testing input is unpaired and PSNR calculation is performed based on the enhanced image and original input.

同学你好，我想问一下你关于环境配置的问题，我现在部署的环境是python3.6,pytorch0.4.1,torchvision0.2.2.但是还是无法进行测试。出现了“cannot import name '_utils'”的情况。想问一下你的环境是什么版本的，怎么解决一些库不适配的问题？谢谢

Pytorch需要0.4.0或0.4.1，“cannot import name '_utils'”看起来是MSDataLoader的问题，但我不清楚你使用pytorch0.4.1为什么会遇到这个问题。可以参考其他类似code使用更高版本pytorch的dataloader: https://github.com/sanghyun-son/EDSR-PyTorch
