我正在 Ubuntu 上使用 PyTorch 實作一個簡單的演算法。我的 NVIDIA 驅動程式已經兩次以某種方式損壞，因此運行演算法會產生以下回溯：
Traceback (most recent call last):
File "module.py", line 212, in <module>
inputs_tensor = torch.tensor(inputs_train).to(device)
File "/home/user/.venv/lib/python3.8/site-packages/torch/cuda/__init__.py", line 172, in _lazy_init
torch._C._cuda_init()
RuntimeError: No CUDA GPUs are available
我重新安裝了驅動程式兩次，但在幾次重新啟動後，它們再次損壞。
