Add plot functions to datasets

[calebrob6]

Working on adding/fixing plot functions for the datasets that don't have them.

Currently on my list

• EuroSAT
• LandCoverAI
• RESISC45
• SeCo
• So2Sat
• UCMerced

RESISC45

@adamjstewart sphinx is failing in the EuroSAT plot function docstring because it can't find the __getitem__ method in the parent class. Have you run into this / do you have ideas?

(also, this will be a rare case where I want to do some preliminary refactoring before having all the initial code out there -- don't worry that the RESISC45 and EuroSAT plot methods are identical!)

I'm actually fine with having similar/same plot methods across datasets. I initially made a single plot method for GeoDataset but I think I want to undo this. Things like normalization are so different across datasets that it makes sense to have dataset-specific methods.

I think you just need to tell it where __getitem__ is defined, so use VisionClassificationDataset.__getitem__ instead.

Awesome, thanks!

I'm seeing the following warning when running the tests:

tests/datasets/test_so2sat.py::TestSo2Sat::test_plot[train]
tests/datasets/test_so2sat.py::TestSo2Sat::test_plot[validation]
tests/datasets/test_so2sat.py::TestSo2Sat::test_plot[test]
  D:\a\torchgeo\torchgeo\torchgeo\datasets\utils.py:569: RuntimeWarning: invalid value encountered in true_divide
    (img - lower_percentile) / (upper_percentile - lower_percentile), 0, 1

I think the So2Sat fake data needs to be updated so that it isn't all zeros and instead contains a range or random numbers.
