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.
