Hi,  When I use libtorch to forward audios with GPU and use torch::NoGradGuard, The first audio file is normal, but the second will appear thread suspending, the GPU utilization become 0. After a moment, this will be fine and never appear suspending. When I use multi thread, they are all  suspending when forward the second audio file in every thread, I must wait quite a long time…
When I use libtorch to forward audios with GPU and not use torch::NoGradGuard, Thread suspending will much better, however, still a few thread suspending I can feel.
I change torch::NoGradGuard into torch::autogrid::AutoGradMode guard(false), get same situation.
I have no idea about that, can anybody help?
