How to Keep Track of Experiments in PyTorch - neptune.ai

Jul 21, 2022Let's start with tracking usual metrics like train/test loss, epoch loss, and gradients. To do this you just have to put run ['metrics/train_loss'].log (loss) with "metrics" being a directory in which you can store the required parameters and "loss" being the metric tracked. This will go something like this in your PyTorch training loop:
