  "In this tutorial, we demonstrate how to extend a TorchGeo [\"trainer class\"](https://torchgeo.readthedocs.io/en/latest/api/trainers.html). In TorchGeo there exist several trainer classes that are pre-made PyTorch Lightning Modules designed to allow for the easy training of models on semantic segmentation, classification, change detection, etc. tasks using TorchGeo's [prebuild DataModules](https://torchgeo.readthedocs.io/en/latest/api/datamodules.html). While the trainers aim to provide sensible defaults and customization options for common tasks, they will not be able to cover all situations (e.g. researchers will likely want to implement and use their own architectures, loss functions, optimizers, etc. in the training routine). If you run into such a situation, then you can simply extend the trainer class you are interested in, and write custom logic to override the default functionality.\n",
