DPSR training problem

[wenfan-wenfan]

Thanks for @cszn contribution, DPSR is an amazing job, so I give author a star to say thanks! But in my training，It takes a long time. When I checked, I found that my CPU usage was very high and GPU usage was very low(such as image1 and image2)，So I wanted to ask： 1.How long does a DPSR training normally take？ 2.Have you ever experienced high CPU usage and low GPU usage before?How do you solve the problem of low GPU usage and high CPU usage?

My email address is [email protected]，I look forward to further discussion with you. image 1： https://imgchr.com/i/8shnK0 image 2 : https://imgchr.com/i/8s4wyq
