真的很简单。只是去你的LightningModule 和海王星实验的调用方法 self.logger.experiment。 例如,我们可以记录每个时期之后的损失直方图: class CoolSystem(pl.LightningModule): def validation_end(self, outputs): # OPTIONAL avg_loss = torch.stack([x['val_loss'] for x in outputs]).mean() ...
Describing model performance using a confusion matrix What is covered in this post We know deep down inside that we require visualization tools to supplement our development. One way could be to make our own small snippets for each making graphs using matplotlib or any other graphing library. ...
