SpaceNet8 Download broken

Steps to reproduce

from torchgeo.datasets import SpaceNet8

ds = SpaceNet8(root=".", split="train", download=True)

Or potentially, I also need to configure something else? I do have aws-cli installed.

Version

0.7.0.dev0

Nevermind, I just need to learn how to use aws-cli properly.

I'm not able to reproduce the exact error message (the download "succeeds" for me), but the downloaded file is corrupted, and tar crashes instead:

> python3
>>> from torchgeo.datasets import SpaceNet8
>>> ds = SpaceNet8(root="data", split="train", download=True)
download: s3://spacenet-dataset/spacenet/SN8_floods/tarballs/Germany_Training_Public.tar.gz to data/SN8_floods/train/Germany_Training_Public.tar.gz

The checksum is indeed different. However, when I download the file outside of TorchGeo, I don't see this issue:

> aws s3 cp s3://spacenet-dataset/spacenet/SN8_floods/tarballs/Germany_Training_Public.tar.gz .
> md5 Germany_Training_Public.tar.gz 
MD5 (Germany_Training_Public.tar.gz) = 5f1c9ac3ea94f2909da593d894680ea2
> tar xzf Germany_Training_Public.tar.gz 

Unclear if this is a transient issue or something else.

P.S. I think I still have SN8 (and all other versions) downloaded on our AI4EO server if you need it immediately.

Also, the lead on SN8 was Ronny Haensch from DLR. I have an email thread with him asking about the SN8 AOIs if you want me to ping him on this. But I think we need to get to the bottom of why it isn't working inside TorchGeo first.

You are right, the corrupted download also happens for the "test" split. I wanted to download the dataset, so I can add a datamodule for spacenet 6 and 8. Spacenet6 downloads fine with no errors.
