Colab runtime crash due to out of system RAM

Hi. Thanks for this amazing work!! I'm trying to follow the "Walkthrough With an Example Sequence" on Google Colab. After something like ~14 hours of training I finally reach the final rendering step. But Colab runtime crashed due to out of system RAM, even when I'm running on a high-RAM instance:

Instructions To Reproduce the Issue:

Please visit this Colab notebook, I basically copy all the codes from "Walkthrough With an Example Sequence", the only modification is to connect to my Google Drive to save training result.

Hi,that might well be the case. I think I only optimized the code to be a bit flexible with respect to VRAM and assumed sufficient RAM. I trained on machines with at least 100-200GB RAM. The issue might be that it probably stores all the intermediate information like the color per point sample on the ray of every ray/pixel in the image.

Hi, I also have the same problem. Besides adding the RAM memory modules, do you have other solutions to the problem?
