How to train with multi GPU and fix low volatile gpu util

Hello everyone, I want to train my model with multi GPU, my server has two RTX 2080Ti GPU image but I just ran only one card and low volatile gpu util is very low. How can I fix this ?

Hi @anhquan075. You should be able to specify the amount of GPUs you have and make sure that your server allocates enough memory for it. You can find more info on that here.
