training speed very slow

The training speed is very slow, did anybody encounter this problem?

And the GPU is in use:

You may try to raise workers_per_gpu.

I tried it but it's much slower...

Have you solved this problem？ I encounter the same issue with the A100 GPU.

The processing of radar point cloud is too time-consuming. You can try the method in Bevstereo. Store the point cloud as an npy file, and then read it.

Thanks for your advice！ Can you give me a demo code?
