TorchGeo 0.3.0 Release Notes

This release contains a number of new features, and brings increased stability to installations and testing.

In previous releases, not all dependencies had a minimum supported version listed, causing issues if users had old versions lying around. Old releases would also install the latest version of all dependencies even if they had never been tested before. TorchGeo now lists a minimum and maximum supported version for all dependencies. Moreover, we now test the minimum supported versions of all dependencies. Dependencies are automatically updated using dependabot to prevent unrelated CI failures from sneaking into PRs. We hope this makes it even easier to contribute to TorchGeo, and ensures that old releases will continue to work even if our dependencies make backwards-incompatible changes.

Backwards-incompatible changes

  • VisionDataset and VisionClassificationDataset have been renamed to NonGeoDataset and NonGeoClassificationDataset (#627)
  • Sample size now defaults to pixel units, use units=Units.CRS for old behavior (#294)
  • RasterDataset no longer has a plot method, subclasses have their own plot methods (#476)
  • Plot method of RasterDataset subclasses now take sample dicts, not image tensors (#476)
  • Removed FCEF model, use segmentation_models_pytorch.Unet instead (#345)
  • SemanticSegmentationTrainer: ignore_zeros renamed to ignore_index (#444, #644)

Dependencies

  • Python 3.7+ is now required (#413, #482, #486)
  • Add lower version bounds to all dependencies based on testing (#574)
  • Add upper version bounds to all dependencies based on semver (#544, #557)
