How to unzip the kaggle datasets?

[qAp]

Hi
Are the zip files downloaded from Kaggle meant to be extracted with a simple unzip command?

Following the instructions in the README, three zip files are downloaded with:

kaggle d download kbrodt/oc-t1-1024-z19-p1
kaggle d download kbrodt/oc-t1-1024-z19-p2
kaggle d download kbrodt/oc-t1-1024-z19-p3

I then ran unzip '*.zip' but this only produced three files, with which I don't know what to do with:

train_tier_1_tiles_1024_z19.zip.partaa
train_tier_1_tiles_1024_z19.zip.partab
train_tier_1_tiles_1024_z19.zip.partac

file train_tier_1_tiles_1024_z19.zip.partaa gives:

train_tier_1_tiles_1024_z19.zip.partaa: Zip archive data, at least v1.0 to extract

I've also tried zip -FF in case the data is corrupted, as well as extracting with jar, but have not been able to go beyond these *.parta* files.

Any ideas? Thanks

Hi,

I've splitted zip file into multiple via split to fit kaggle limit of 20Gb. You can use cat to merge all of them, e.g. cat train_tier_1_tiles_1024_z19.zip.parta* > train_tier_1_tiles_1024_z19.zip. Try both, merge downloaded files into one and then unzip or unzip and then merge.
