DeepFaceLab_Linux Uses 100% CPU simultaneously with GPU

Has anyone else found this? I don't recall this happening in the windows version.

Thanks.

I got nothing for this one.....my CPU is 91% idle while my GPU is chugging away training at the moment.

Yeah crazy right? I know there is that question in the startup script, that says how many CPU cores to use - which I usually max out - I always figured it was only for tasks that GPU doesn't do, but maybe it doesn't work like that? Maybe it was windows that was broken.

OK, I've confirmed that this directly changes when selecting how many CPU cores you want to use in the startup script. While that might sound obvious, note that I have not selected to use CPU for training, only GPU. So it would seem to me that something in the script is enabling the CPU for training without user input - unless there is some other CPU usage that is bugged. I can see clearly in top that the cpu is in use by python3.9, but that's about it so far.

I have the same problem on Ubuntu22.04, my graphics card RTX4090 only uses 396MB of video memory
