OOM error using Java Pytorch

1

Hi,

I’m trying to create an image editor app for Android using Pytorch Java and I get this error using module.forward(…) with large images :

It works fine with small images (500x500) but I need to use larger images, at least 2K. Do you have any idea of how I could use it with large images ?

Thank you
