LSUN Church FID measurement with DDPM

[hjinnkim]

Hello, I'm currently training using experimental code in your repo.

Based on your code, I successfully measure FID of pretrained DDPM with your sampling code.

However, when I measure FID of pretrained DDPM for LSUN Church, the measured FID is only 28.

I guess, it may be due to different pre-processing of dataset.

Could you let me know how you sampled for LSUN Church and measure FID for it?

Thank you for advance.
