Why do we need to call zero_grad() in PyTorch? - Stack Overflow In PyTorch, for every mini-batch during the training phase, we typically want to explicitly set the gradients to zero before starting to do backpropagation (i e , updating the Weights and biases) because PyTorch accumulates the gradients on subsequent backward passes This accumulating behavior is convenient while training RNNs or when we want to compute the gradient of the loss summed over
