I deploy a pretrained deep model on NVIDIA V100 GPU. After infering lots of images, I find Volatile GPU-Utils still shows 100%, but no infering is running now. How to fix this problem?
When I type  nvidia-smi , it shows:

| NVIDIA-SMI 384.183 Driver Version: 384.183 CUDA Version: 9.0 |
|-------------------------------±---------------------±---------------------+
| GPU Name Persistence-M| Bus-Id Disp.A | Volatile Uncorr. ECC |

| N/A 43C P0 51W / 250W | 2530MiB / 32502MiB | 100% Default |

I have tried  sudo nvidia-smi -pm 1  to enable Persistence Mode. But the problem still remains.
