调用torch.cuda.is_available()报错如下
/opt/conda/lib/python3.8/site-packages/torch/cuda/init.py:138: UserWarning: CUDA initialization: Unexpected error from cudaGetDeviceCount(). Did you run some cuda functions before calling NumCudaDevices() that might have already set an error? Error 803: system has unsupported display driver / cuda driver combination (Triggered internally at ../c10/cuda/CUDAFunctions.cpp:108.)
