Do the pre-trained DiT chekpoints contain EMA weights?

[jmkim0309]

I have downloaded the official checkpoint named "DiT-XL-2-256x256.pt", and when I loaded it with torch.load, I could not find "ema" key in there. So I wonder whether these are ema weights or just base model weights?

you may be right, because there is only "model" part without "ema", "opt","args".
I have trained another lightening model including above 4 parts.
