WebDec 6, 2024 · PyTorch Server Side Programming Programming Tensor.detach () is used to detach a tensor from the current computational graph. It returns a new tensor that doesn't require a gradient. When we don't need a tensor to be traced for the gradient computation, we detach the tensor from the current computational graph.
