Here’s the simplest most minimal example with just a training loop (no validation, no testing). Keep in Mind - A LightningModule is a PyTorch nn.Module - it just has a few more helpful features. By using the Trainer you automatically get: 1. Tensorboard logging 2. Model checkpointing 3.

Assuming (for simplicity) that the batch size is 1, this will log the accuracy for 1 sample and it will be displayed as a chart in the w&b ...

You can use TorchMetrics in any PyTorch model, or with in PyTorch Lightning to enjoy additional features: This means that your data will always be placed on the same device as your metrics. …

TorchMetrics is a collection of machine learning metrics for distributed, scalable PyTorch models and an easy-to-use API to create custom metrics. It has a collection of 60+ PyTorch metrics implementations and is rigorously tested for all edge cases. pip install torchmetrics. Copy to clipboard. In TorchMetrics, we offer the following benefits:

As already mentioned, these metrics (even the already implemented ones!) can also be used without anything else from PyTorch Lightning! Let’s have a look at this short example: import torch from pytorch_lightning. metrics. functional import accuracy # our mocked predictions - for real usage drop in your fancy method here!
