对于更高版本的 PyTorch，您的意思是所有的 backward function，都需要设置 "retain_graph=True, create_graph=True" ？

“If you use our code based on a high-level version of PyTorch for other tasks, please ensure the "retain_graph=True, create_graph=True" in the backward function. ”

对于更高版本的 PyTorch，您的意思是所有的 backward function，都需要这么设置吗？

你好，请问你这个是如何设置的？我是pytorch0.4

[wangxiao5791509]

@Tomingz I am not sure, the author did not give any response yet. I think all the backward functions should be modified. It is more intuitive to directly use PyTorch 0.2 to train and test this code.

[Tomingz]

ok.thank you,I will test by pytorch0.2

where is the backward function?
I cannot find the retain_graph=True, create_graph=True.
