Detach function pytorch
WebDec 29, 2024 · Summary: actually detach () and detach_ () very similar. The difference between the two is detach_ () is a change to itself, and detach () generates a new tensor. For example, in X - > m - > y, if you detach m (), you can still operate the original calculation diagram if you want to go back later. But if detach is performed_ (), then the ... WebApr 8, 2024 · In the two plot() function above, we extract the values from PyTorch tensors so we can visualize them. The .detach method doesn’t allow the graph to further track the operations. This makes it easy for us …
