请问怎么输出第八章运行后的图片呢？

在177-178页，开始训练时，进程会卡住，使用github上的代码也同样会卡住，GPU使用率为0%。python 3.7.8；torch 1.10.1+cu113.希望老师能解答一下，谢谢。

书中的代码没有电子版吗？？？

书P177代码执行出现问题，报错如下
File “H:\pytorch学习记录\6.4.02.py”, line 98, in <module>
loss.backward()

File “C:\Users\Stein\anaconda3\envs\pytorch\lib\site-packages\torch\tensor.py”, line 221, in backward
torch.autograd.backward(self, gradient, retain_graph, create_graph)

File “C:\Users\Stein\anaconda3\envs\pytorch\lib\site-packages\torch\autograd_init_.py”, line 130, in backward
Variable._execution_engine.run_backward(

请问有解决办法吗

P173代码运行报错，内容如下

请问如何解决？
