requires_grad require_grad means whether the gradient needs to be calculatedWhen using the backward() function to calculate the gradient, the gradient of all tensors is not calculated. Only the gradient of tensors that meet the following conditions can be calculated: 1 Current tensor requires_ Grad = true (code example 1); 2. Require of all te ...
