SSIM & LPIPS calculation

[moff-bro]

Hey
Thankyou for the wonderful code. I am curious to know how were SSIM and LPIPS metrics were calculated in the code. I was able to find PSNR but nothing for the other two and all three are mentioned in the paper?
Can anyone point me to the line in the repo where SSIM and LPIPS are calculated?
Thankyou very much.
