MPR_Net deraining单卡训练loss下降不明显,且psnr一直是inf,而ssim几乎恒定不变。但是原作的MPR可以正常训练,几乎同样的配置,不确定是PaddleGAN/ppgan/metrics/psnr_ssim.py/calculate_psnr.py:96的calculate_psnr有问题还是paddle的问题。

inf大概是因为验证集里恰好截图到了近乎纯色的,导致去雨后和原来完全一样,loss不下降我也遇到了,还有loss突然上升到很大,然后就不下来了
Sorry, something went wrong.
您好,请问问题还是否需要解决,目前相关图像生成能力集成在PaddleMIX中,https://github.com/PaddlePaddle/PaddleMIX/tree/develop 可以在这个repo下提出您的需求
