[Sovled] When the laptop automatically suspend and wake up cuda go bad

I met a strange phenomenon:

After I leave my laptop for a long time, I come back, wake up my laptop from suspended status, cuda will not work.

```python
import torch
torch.cuda.is_available()
/home/wzy/.pyenv/versions/3.9.13/lib/python3.9/site-packages/torch/cuda/__init__.py:52: UserWarning: CUDA initialization: CUDA unknown error - this may be due to an incorrectly set up environment, e.g. changing env variable CUDA_VISIBLE_DEVICES after program start. Setting the available devices to be zero. (Triggered internally at  /pytorch/c10/cuda/CUDAFunctions.cpp:115.)
  return torch._C._cuda_getDeviceCount() > 0
Out[2]: False
```

When I reboot my laptop, the strange phenomenon will disappear.

Anyone know the possible reason? Thanks!

After update, this phenomenon disappears.
