Memory overflow problem

[wangchaofan2018]

When I train using the sdfstudio dataset converted from the nerfstudio dataset, I notice that the memory consumption is very high during data loading, continuously increasing until the memory is fully occupied. Given that my computer has 128GB of RAM, I'm confident that there's a bug present. Currently, I'm training directly with the nerfstudio dataset, and I'm unsure if this will impact the training results.

Same thing. It would be nice to see something hierrarchical, or merging
