CUDA kernel errors might be asynchronously reported at some other API call,so the stacktrace below might be incorrect.
For debugging consider passing CUDA_LAUNCH_BLOCKING=1.

torch版本不匹配

1.卸载torch

2.安装相应版本

3.测试：

torch.cuda.is_available() 只是检测CUDA是否安装正确并能被Pytorch检测到
a=torch.Tensor([1,2])
a=a.cuda()
