Web14 de nov. de 2024 · The graph is accessible through loss.grad_fn and the chain of autograd Function objects. The graph is used by loss.backward () to compute gradients. optimizer.zero_grad () and optimizer.step () do not affect the graph of autograd objects. They only touch the model’s parameters and the parameter’s grad attributes. WebCalling minimize () takes care of both computing the gradients and applying them to the variables. If you want to process the gradients before applying them you can instead use the optimizer in three steps: Compute the gradients with tf.GradientTape. Process the gradients as you wish. Apply the processed gradients with apply_gradients ().
