Fix file-specific test coverage

[adamjstewart]

@calebrob6 does this fix the issue you reported? It works for me, but I'm not 100% sure it will always work for everyone. If you can figure out a way to break this I'll reach out to the pytest-cov developers because I really want this to work, especially as we increase the number of datasets.

[calebrob6]

Nope, same error. Were you able to reproduce?

Similarly, there are a bunch of errors if I simply do pytest --cov=torchgeo.datasets.landcoverai.

Tracking issue here #2541

[adamjstewart]

I'm not able to reproduce, it sometimes works for me and sometimes doesn't. I think we should reach out to the pytest-cov folks to get more explanation of what is and isn't supposed to work.

[calebrob6]

You are saying that sometimes pytest --cov=torchgeo.datasets.landcoverai tests/datasets/test_landcoverai.py gives the same error that I got but sometimes it works as expected?

By the way, if I replace the contents of test_landcoverai.py with simply import torchvision I get the same answer.

[adamjstewart]

It's probably dataset specific. For example, advance works, but landcoverai fails.

[calebrob6]

Advance doesn't work for me....
