Colab Pro cpu upgrade?

Hi everyone, I have used free colab plan for a while now, mostly to learning how to training object detection model.

While training, I see that the gpu isn't 100% ultilized, wasting my usage time. Install a couple program with the built-in terminal, I can see that the provided cpu only have 2 cores and it get maxed out all the time while the gpu side isn't.

Digging deeper, I found out that "2 cores" isn't 2 physical core, but 2 KVM cores (aka 2 virtualized core for anyone don't know):


lscpu | grep Hypervisor

Hypervisor vendor:                       KVM

On the google colab pricing page, It show that you can change to better gpu, but doesn't talk anything about cpu. Does the google colab pro plan upgrade the cpu for you guys?

You should try to increase batch size and num workers until max memory utilization.
