Dear authors,

thanks for your great work!

I would like to know do you use mixed precise for training? e.g. torch.amp = True or torch.cuda.amp.autocast(enabled=use_amp)?

I found that mip-splatting rasterization only support fp32 so I guess you didn't enable amp? But flash attention only support fp16. So I'm confused.

Best,
