Thanks, I’ll post my results relative to that part by tomorrow. I imagine that with pytorch using the gpu I should attain something in between your laptop and your monster rig (given that you are using just one 1080ti). I’ll keep you posted.
For the moment, let me say that I obtained the result I posted on a nb I written down from scratch (as I usually do). The same code executed on the standard nb provided by fastai repo is carried out almost instantaneously, the first time you execute it. I’m clearly making some stupid mistake, having slept 6 hours in 3 days. My best guess is that the gpu is initialized by pytorch, but it is not released once it finishes its job. Either that, or I’m suffering memory leakages
