 Here we trained a NGP Nerf model on the NeRF-Synthetic dataset. We follow the same
 settings with the paper, which uses trainval split for training and test split for
-evaluation. Our experiments are conducted on a single NVIDIA TITAN RTX GPU.
+evaluation. Our experiments are conducted on a single NVIDIA TITAN RTX GPU. The training
+memory footprint is about 3GB.
 
 .. note::
     
     The paper makes use of the alpha channel in the images to apply random background
     augmentation during training. Yet we only uses a constant white background.
