Questions about the training time

[JCBreath]

Hi, I appreciate that you shared your great work.
I am wondering how you computed the training + inference time in Table 2 in the paper.
When I run the code on hotdog dataset for example, it takes around 25hrs to complete the training.
However, in your paper, you stated it should be around 2hrs.
For what I have experienced with Vanilla NeRF, the training is taking about 20+ hrs.
Thanks for any insights.

It is really memory and time intensive, runs out of memory for me. I have a 4GB GPU available to me. Even reducing N_rand is not helping.
