Hello, There is a suspicious order of commands in the training_loop function of the “Training Embeddings with a Simple Model“ segment of the second lab of the module (please, see the attached screenshot below): [image] Usually a loss is accumulated before(!) gradients are calculated and updated,…

It appears to me that “epoch_loss” is a local variable inside that function, and that it is not used by the backward propagation and gradient calculation. So the order of that statement should not matter. Technically, computing the gradient does not actually use the loss value - it only uses the m…
