Hi, my PC is configured with an RTX 4070 and an Intel i7-13700. During installation, I selected the NVIDIA GPU option. However, when I started training, I noticed the following issues: the CPU usage is at 100%, while GPU usage remains between 0–3%. I also checked the backend monitor to confirm this.
I’ve tried reinstalling, but the problem still persists. Could you please advise me on how to fix this?
Thank you very much for your help!

thank you for your understanding.)
