Training Details about invertible-image-rescaling

Yes it will cost these time to train 500k iterations. The default config is the correct one.

Can you reproduce the DIV2k_val psnr? I train for 3 days and I think I cannot get the 44 psnr.

Is that the tensorboard show the PSNR and the paper show the PSNR_Y? @pkuxmq

@ManWingloeng Yes, the training code only calculates RGB PSNR, and the testing code will calculate both RGB PSNR and Y PSNR. We report Y PSNR in the paper following the setting of other works. For IRN_x2, the final RGB PSNR should be around 40.8dB.
