Training time

[sstzal]

Hi, Alex
Can you show me how much time is needed for training on the ShapeNetv2 and other datasets?

I find that about 400000 iterations is sufficient for shapenet datasets, and 250000 for LLFF and Blender.

Hi, Alex
Sorry to ask one more question (lazy). I want to know how much GPU memory (how much G?) is used when training this model?

Feel free to ask as many as you need. With memory, I also load all of the shapenet dataset into memory, so you need a good amount of RAM as well, 32gb should be sufficient.

With regard to VRAM, Shapenet usually uses around 12-13gb during training, and I maxed out a 32gb v100 for the other datasets. You can adjust the batch size (N_rand) in the configs to make it work with less RAM, as long as its not too low.
