Hi, @Zafar  Thank you for the reply. I use this dataset as my training data:

It seems that the original download link is dead, so I upload a torrent here:

BTW, for the result of SNR shown in your code, does it mean that, a small number shows the result between original model and quantized model are close to each other?
