We talked about the tracking of each loss' components to figure out that x^2 can't be approximate by a Linear but 2*x can.
loss = loss1 + loss2
loss.backward()
return {"loss": loss.item(), "loss1": loss1.item(), "loss2": loss2.item()}

Add this to track losses
RunningAverage(output_transform=lambda x: x["loss"]).attach(trainer, "loss")
RunningAverage(output_transform=lambda x: x["loss1"]).attach(trainer, "loss1")
RunningAverage(output_transform=lambda x: x["loss2"]).attach(trainer, "loss2")
@trainer.on(Events.EPOCH_COMPLETED)
def iteration_results(trainer):
metrics = trainer.state.metrics
print(f"Iteration Results - Epoch[{trainer.state.iteration}] Metrics: {metrics}")

@Priyansi I left a few comments to track the losses. What do you think ? |
