DataLoader worker (pid 1 4698) is killed by signal: Killed Error

[cauliflower0077]

I tried to train DINO on an original combined dataset consisting of about 2000 training images and about 500 validation images.
However, I got the following error. Please tell me how to resolve it.

Firstly, I had success using 500 training images and 100 validation images, but now I would like to train with a larger number of images.
Additionally, I attempted to fix PyTorch DataLoader. Could you please let me know where I can find the 'pin_memory=true' option in DINO repository?
I want to create a robust AI model, so ‘number of class‘ is set to 1.
