pytorch_msssim库的不同版本可能与不同版本的PyTorch兼容。你需要查阅pytorch_msssim的官方文档或GitHub仓库的README文件,了解与你当前安装的PyTorch版本兼容的pytorch_msssim版本。如果版本不兼容,你可能需要升级或降级其中一个库。 查阅pytorch_msssim.ssim()的文档,确认其使用方法和参数: 你需要查阅pytorch_msssim.ssim...

For ms-ssim, there is no nonnegative_ssim option and the ssim reponses is forced to be non-negative to avoid NaN results. Tests and Examples cd tests 1. Comparions between pytorch-msssim, skimage and tensorflow on CPU. # requires tf2 python tests_comparisons_tf_skimage.py # or skimage on...

After looking briefly atpytorch-msssim, I understand the difference now. The issue is that these are not the same algorithm and should not be expected to match! pytorch-msssimimplements a variant of SSIM known as "multi-scale" SSIM (MS-SSIM) while the one here is the original SSIM method...

MS-SSIM is a particularly unstable metric when used for some architectures and may result in NaN values early on during the training. The msssim method provides a normalize attribute to help in these cases. There are three possible values. We recommend using the value normalized="relu" when tr...
