About pytorch 0.4 in Windows

I installed pytorch 0.4 on the official website using the following code:
pip install http://download.pytorch.org/whl/cu80/torch-0.4.0-cp35-cp35m-win_amd64.whl
pip install torchvision

It seems everything is normal,but I found the usage of GPU is low and CPU is high!
I want to use GPU,is this normal?

The GPU usage depends on your workload.
Try to increase the calculations and check the usage again, e.g. by creating a large CNN.
