The linked video shows some information on that https://youtu.be/obrmH1T5mfI?t=288 And in the paper: https://arxiv.org/pdf/2103.14024.pdf > As training time poses another hurdle for adopting NeRFs in practice (taking 1-2 days to fully converge), we also showed that our PlenOctrees can accelerate effective training time for our NeRF-SH.

if they were to use deepspeed/zero 3 can we expect training time to be significantly reduced ?
