How to check pytorch installation error?

import torch

torch.backends.cuda.matmul.allow_tf32 = True

torch.backends.cudnn.benchmark = True

torch.backends.cudnn.deterministic = False

torch.backends.cudnn.allow_tf32 = True

data = torch.randn([1, 512, 120, 67], dtype=torch.float, device='cuda', requires_grad=True)

net = torch.nn.Conv2d(512, 512, kernel_size=[3, 3], padding=[1, 1], stride=[1, 1], dilation=[1, 1], groups=1)

net = net.cuda().float()

out = net(data)

out.backward(torch.randn_like(out))

torch.cuda.synchronize()
