About reconstructed image and MS-SSIM for TF2 version model.

[shahid abbas]

Hi Johannes,

I trained your model by myself, here I have two queries.

1. Reproducibility Problem: Once the training is complete and if I want to encode and decode the image, where sometimes the reconstructed image is not decoded properly. sample image is attached.
2. MS-SSIM: I use the ms-ssim function "train_loss=tf.reduce_mean(tf.image.ssim_multiscale(x,x_tilde,255))" in T2 dependent model but after completing training the reconstructed image doesn't seem like original (reconstructed image is either black or gray). but the same function works properly in the model which is dependent on TF1 version.   

Will be waiting for your kind guidance.

Best Regards

Shahid
