解决问题：AssertionError: Torch not compiled with CUDA enabled

error：

AssertionError: Torch not compiled with CUDA enabled

此错误是由于下载的torch没有cuda,在运行时就会出错，经过查阅，在程序最开始的地方加上：
device = torch.device(“cuda” if torch.cuda.is_available() else “cpu”)
代码其余地方出现.cuda()的地方改成.to(device)就可以在无gpu的环境中运行了。

# model.cuda()
model.to(device)

# prediction = model([image.cuda()])
prediction = model([image.to(device)])
