Unable to open zipped features
Hi, thank you for open-sourcing this exciting dataset. I am trying to open the feature zip files, however, trying to unzip them wtih unzip test_features_splits.zip
yields error: invalid zip file with overlapped components (possible zip bomb)
, and trying 7z x test_features_splits.zip
yields ERROR: Unavailable data
. I have also tried concatenating the individual .z01, etc
files cat test_features_splits.z* >test.zip
and then unzip test.zip
but with no success and haven't found another solution. The same applies for the train features. Thus I was wondering if you could provide a command to properly extract the data? Thanks in advance :)
Hi, I have the same issue, is there a solution?
I think in the original data came with a .txt file explaining how to unzip the files, can you add that?
Following solution worked for me for train_features data (downloaded the 'train_features.z{number}' files and 'train_features.zip' folder manually): All '.z{number}' files + zip folder have to be in the same directory. Then I used 7-Zip to unzip the 'train_features.z01' file and suddenly the entire contents of all '.z{number}' files + zip folder were unzipped at once. The feature data is usable now.
Previously I tried to unzip and use only the data from 'train_features.zip' because I didn't know what the 'train_features.z{number}' files were all about. It turned out that the number of unzipped files of the zip folder was exactly the same as the complete train_features part of the dataset, but most of these files were empty. Apparently, these unpacked, empty files were just placeholders for the actual files. My assumption is therefore that the 'train_features.z{number}' files and the 'train_features.zip' folder all represent splits of the train_features data, which are dependent on each other with regard to unzipping and must therefore be in the same folder for unpacking.
Very thankful for this open source dataset, however the instructions for downloading and using it could really be more precise.
@asaphs We rehosted the dataset on torchgeo HF as tar balls with extraction instructions. We have not supported hugginface dataloader, but instead have one in torchgeo. Maybe that helps, let us know.
