The CPU usage is too high.

Thank you for your great work. I am currently using the nuscenes dataset to reproduce your code. However, I have noticed that the CPU usage during training is extremely high. My CPU has 32 cores, and each training session utilizes all cores, with each core's usage reaching close to 100%. Therefore, I am unsure if such high CPU usage is normal. Perhaps you know how to adjust and lower the CPU core usage? Looking forward to your response.
